Tomato leaf minor (Tuta absoluta ) is a noxious insect pests of tomato crop globally, cause huge losses of tomato in every season. Therefore, the present research was conducted to evaluate effectiveness of management trapping devices for T. absoluta in tomato field. Management traps show varied significantly in their effectiveness to capture moths, maximum mean (25.25±3.52) moths were caught by delta pheromone trap followed by light traps (14.78±1.89), color sticky traps (10.23±2.67) and water pan trap (5.61±01.56), respectively. Due to maximum capture of adult in delta pheromone trap, light trap devices and cultural practices, the lowest (11.90±2.67 %) tomato leaves infestation was recorded in delta type pheromone trap followed by cultural practices (13±2.80 %), light traps (15.35±3.12 %), color sticky traps (20.00±2.80 %), water pan trap (31.13±05.56 %) and control (35.13±04.50 %). However, lowest (05.59±03.62 %) infestation tomato fruit was recorded in delta type pheromone trap followed by cultural practices (8.50±2.1 %), light traps (09.64±02.88 %), color sticky traps (13.81±03.10 %), water pan trap (19.88±03.15 %) and control (22.10±04.50 %), respectively. Results showed the highest yield (6546.60 kg/acre) was obtained in the plots where delta type pheromone traps were installed, followed by plots in which cultural practices were carried out (6476.80 kg/acre), light traps (5943.70 kg/acre), color sticky trap (5863.20 kg/acre), water pan trap (5684.30 kg/acre) and in control (5426.00 kg/acre). The maximum cost benefit ratio (4:18) from the plots where delta pheromone traps were installed followed by cultural practices (4:16), light traps (4:12), color sticky traps (4:10), water pan trap (4:07) and control (4:02), respectively. The highest adult attraction and lowest crop damage with maximum fruit production was recorded after the application delta pheromone traps with cultural practices, thus it is recommended; that the delta pheromone traps along with cultural practices are the convenient practices to monitor and control adult population of tomato leaf miner in infested tomato field.

Among the various potential vegetables, tomato is one of the high value crops, with growing market demand and higher level of return per hector. South American Tomato leaf miner, Tuta absoluta is one of the main constrains in tomato production in Nepal. Field experiments were conducted from June to October 2017 to determine the attractive action of trap colours against T. absoluta management in Lele VDC, Lalitpur, Nepal. Experiments were setup using different types of traps (Delta trap, Wota-T trap and solar light trap) each with pheromone capsule i.e. TLM lure. Particularly, in this experiment the influence of color (orange, white, yellow and green) in delta trap, height adjustment from ground level - 1 feet, 2 feet, 3 feet and 4 feet) in Wota-T trap and; locally prepared light traps of led bulb, solar light trap with high power of 65 lumens and solar light trap with low power of 25 lumens to capture Tuta moth were tested. For the evaluation of effectiveness of different types of traps, number of Tuta moths captured were recorded. The results demonstrated that T. absoluta moths can distinguish between the colours. White colored delta trap captured maximum mean number of Tuta moth (22) followed by green (16), yellow (13) and orange (10). Similarly, Wota- T trap when placed at different height, trap placed at ground level captured maximum mean number of Tuta moths (15) followed by One ft (12), Two ft(11), Three ft(8) and Four ft(2). Among the different types of light trap solar light trap with high power of 65 lumens captured maximum mean number of Tuta moth’s (5) followed by solar light trap with low power of 25 lumens (3) and locally prepared light trap with led bulb (2). Significant differences between mean moth catches by different colored delta traps, wota-T trap placed at different height and different types of light traps were observed. Based on the study conducted with in a season it were found that trap color, trap height and light trap types are the characteristics that strongly affect the response of T. absoluta moths to pheromone-baited traps. From the study it is clear that, these traps can be used as one of the best sex pheromone based management strategy for the management of T. absoluta moths. Further research is recommended for better understanding of the effect of trap colour on the diversity and abundance of non target insects captured

AbstractRapidly changing environments and an increase in human movement around the globe have contributed to a rise in new and emerging diseases, many of which are arthropod borne. The threat posed to the United Kingdom by such diseases is uncertain, and there is a real need to understand the distribution, seasonality and behaviour of potential vectors in the country. At present, there is no standard method for routine mosquito surveillance in the UK. Here we compared the catching efficiency of two carbon dioxide-baited traps, the CDC light trap and the MosquitoMagnet® Pro trap, for collecting British mosquitoes. Two of each type of trap were operated at four sites in central and southern England from June to September, 2003. To determine whether trap height affected collections, three light traps were operated at 1, 2.5 and 5 m above the ground in one site in 2004. Both types of trap were efficient at catching mosquitoes, collecting 5414 mosquitoes of 16 species. MosquitoMagnet® traps caught 2.7 times more mosquitoes than CDC light traps (P<0.001) and a wider range of species (16 species vs 11) than CDC light traps. Four to six times more female Culex pipiens s.l. were collected in light traps at 5 m (P<0.001) compared with traps at lower heights. MosquitoMagnet® traps ran continuously for up to 8 weeks, whilst the battery of a CDC light trap had to be replaced every 24 hrs. Although MosquitoMagnets® collected more specimens and a greater range of mosquito species, they were considerably more expensive, prone to breakdown and incurred higher running costs than the CDC light traps. MosquitoMagnets® are useful tools for collecting mosquitoes during longitudinal surveys during the summer months, whilst CDC light traps are to be preferred for rapid assessments of the presence or absence of mosquitoes, particularly the important species Culex pipiens.

One solution to solve pest problems in shallot cultivation is to apply the concept of Integrated Pest Management (IPM). An example of IPM that can be used is the use of light traps and sex pheromone traps, where both traps have been proven to be able to control the population of S. exigua Hubner in shallot plants. This study used RAK (Randomized Group Design) with 1 factor, namely the type of trap. The observation variables observed were the number of trapped imago, the number of egg clusters, the intensity of the attack, and production yield. Based on the results showed that S. exigua Hubner imago was more trapped in the lamp trap which amounted to 197.67 heads than the sex pheromone trap which only amounted to 14.01 heads. The number of egg groups in the sex pheromone trap plot was 0.28 and in the light trap plot was 0.18. The larval population in the sex pheromone trap plot was higher at 3.58 individuals than in the lamp trap plot at 3.16 individuals. The intensity of S. exigua infestation in the light trap plots was lower at 126.66 while in the sex pheromone trap plots, it was 155. The use of light traps to control the S. exigua population also provides higher production and profit than using sex pheromone traps.

Culcioides biting midges (Diptera: Ceratopogonidae) are vectors of various veterinary pathogens. Suction light traps are one of the most widely used tools for vector surveillance. The present aim was to compare the efficiency for the collection of Culicoides species between newly developed 3D-printed ultraviolet (Mahidol University (MU) UV LED) and green light-emitting diode (Mahidol University (MU) Green LED) traps baited with CO2 and UV LED Center for Disease Control (CDC) light trap (BioQuip 2770) baited with CO2. The experiment consisted of two replicates of a 3 × 3 Latin square design in each three sampling locations (Location 1, 2, 3 and 4, 5, 6), for 12 nights between 26th July and 7th August 2020 in Thailand. Results showed that efficiency of the MU UV LED light trap was equivalent to that of the BioQuip 2770 trap for the collection of Culicoides. Meanwhile, the efficiency of the MU Green LED light trap was lower than that of both UV LED light traps. In the analysis of Culicoides species composition and sex–age grading, a similar pattern was observed among three light traps except for Culicoides actoni Smith. The newly developed 3D-printed UV LED light trap demonstrated the following advantages over the commercial light trap: cost saving to obtain multiple units, ease of customization and standardization, and increased availability by end-users. Although further assessments in different environmental conditions are needed, this 3D-printed light trap design could minimize the constrains in vector surveillance programs worldwide.

The author studied the impact of the light tube and the distance of the light trap from the Poltarica stream on a caddisfly catch. Four light traps, containing blacklight and bluelight tubes, respectively, were placed at different distances from the stream bank. The most efficient was the light trap placed 10 m away, followed by the light trap at the stream bank and the light trap 50 m away. However, males of the most abundant species Potamophylax cingulatus, which belonged to two subspecies, showed different distributional pattern. Among the used light traps, the one containing bluelight tube was less efficient than those with blacklight tubes.

Light traps have been long used to reduce and manage insect populations. Although there are numerous types and designs of insect light traps. Four distinct light traps were employed for the study and positioned within the BSP Unit Adhartal, JNKVV Jabalpur from mid-November 2022 to mid-April 2023 for the study of the efficiency test of different funnel diameters of light traps based on performance. Comparative studies of light trap catches revealed that 50 cm funnel diameter light traps have given higher response in following species for Helicoverpa armigera (13.91%), Agrotis ipsilon (14.36%), Creatonotus gengis (13.97%), Gryllus bamaculatus (22.26%), Gryllotalpa orientalis (45.30%), Nezara viridula (9.82%), Amata cyssea (13.35%), Asota ficus (7.01%), Perina nuda (21.78%), and Thysanoplusia orichalcea (22.75%). There was a statistically significant increase in trap catches in the 50 cm funnel diameter light traps compared to the 40 cm funnel diameter traps. However, there was a statistically non-significant difference between the 40 cm and 50 cm funnel diameter traps for Spodoptera litura and Theretra oldenlandiae species, although the trap catches were numerically higher in the 50 cm funnel diameter traps because 50 cm funnel diameter provide large catchment area for insects.

 Nocturnal insects are a type of insect that is active at night and plays a role in maintaining the balance of the ecosystem and has an ecologically and economically occurring role. This study was conducted to determine the diversity, evenness, and dominance of nocturnal insects based on the color of the light trap lamp at the Vegetable Crop Research Center of Tongkoh Village, Karo Regency, North Sumatra. This study used the light trap method by making a transect 100 m long and on the transect, 5 observation stations were installed. There are 27 insect families consisting of 35 types of nocturnal insects with a total of 240 individuals. The most common type of insect found is Empoasca fabae. The diversity index (H') is included in the moderate category with a value of 2.10 on the green lamp trap, 1.38 on the blue lamp trap, 2.23 on the yellow lamp trap, 2.76 on the white lamp trap, and 2.26 on the red lamp trap, this shows that the insect diversity at the study site is in a stable condition. The dominance index (C) is categorized as low with a value of 0.184 on green light traps, 0.347 on blue lamp traps, 0.222 on yellow light traps, 0.092 on white light traps, and 0.150 on red light traps. This situation occurs because there is no type of nocturnal insect that is too dominant so that the diversity of insects is classified as being in a stable state.

This study was carried out in the village of Kane kawai chbux, located in the Sulamani governorate of Iraq in 2021. Two options were used to suppress population destiny: a bait trap and a light trap. The effect of color and light density on the attractiveness of adults of the moth Ocnerogyia amanda species of moth leaf worm of fig was studied, and the results showed that light traps yellow color were more effective than white color, Whereas the means monthly captured of adults/trap had (6.278,14.400,12.078), and white light traps means captured adults/trap monthly had ( 6.830,10.488,10.080)The results of the statistical analysis also showed significant differences between white light traps and yellow light intensity with (50, 100, and 150) watts of bulb power, and traps with a 50-watt bulb had less influence on adult capture. Molasses with water at 1:9 and molasses with vinegar at 1:3. The mean monthly captured adults/trap had (7.304, 3.018, and 0.041).Fermented palm sugar and water were superior in attracting a significant number of captures as compared to vinegar and molasses. Molasses and vinegar were the least attractive. The conclusion is that bait traps are an attraction and capture, and that collectors and attraction are aids to light traps that capture most adults active at night as the best method to reduce population density, these are the two selected methods and their relationship as integrated pest management methods.

Several types of light traps are being used in different European countries to help determine the potential vector species of bluetongue virus (BTV). The four traps compared in this study were: i) the Onderstepoort trap – black light trap, with 8 W ultraviolet light tube used in the United Kingdom and Italy; ii) mini-CDC – black light, model 912, with 4 W UV light tube, used in Spain and Portugal; iii) Rieb trap, white light model, with 4 W UV light tube, used from 2000 to 2006 in France; iv) UK trap, with 4 W standard white incandescent bulb, used in the past in the UK and other European countries for African horse sickness surveillance. All traps included a downdraught suction fan. Tests were conducted from 18 Oct. to 19 Nov. 2007, from 18 Feb. to 4 June 2008, and from 1 Oct. to 28 Nov. 2008. During at least nine non-consecutive nights the traps were placed following a randomized block design in four different positions on a cattle farm located on the island of Mallorca (Balearic Islands, Spain). In 2008, only three traps (Onderstepoort, UK and mini-CDC) were tested. Results showed major differences in collecting Culicoides. The Onderstepoort trap showed the best performance in terms of total number of Culicoides captured in autumn both in 2007 and 2008. The UK trap, and especially the Rieb trap showed the lowest efficacy in terms of captures. In autumn 2008, the Onderstepoort trap captured on average 90 Culicoides per night, whereas the mini-CDC captured on average 27. During spring 2008, however, the mini- CDC performed better as it captured on average 180 Culicoides per night, against 84 captured by the Onderstepoort. However, Fisher’s least significant difference test showed no statistically significant differences between the traps (P < 0.05). No remarkable difference was observed between the four traps as they all captured a similar range of species. Captures of Culicoides newsteadi were greater during the autumn, and those of C. obsoletus in the spring. Finally, the Onderstepoort trap showed a higher sensitivity in catching Culicoides midges in low population levels of the vector, especially during the winter season.

ABSTRACT Efficient detection of multiple species of adult mosquitoes in various habitats using effective traps is a crucial 1st step in any disease prevention program. Novel trap types that target tropical vectors of human diseases require field testing in the habitat of the vector–disease system in question. This paper analyzes a series of mosquito trapping studies conducted at Mapacocha, San Juan Bautista District, Loreto, Peru, during August–September 2013 and April–May 2014. Six trap configurations were evaluated in forest and rural locations. Adult mosquito counts were analyzed using full Bayesian inference of multilevel generalized linear models and posterior probability point estimates of the difference of means of the combined trap catch by trap type comparisons of all species. Light traps (Centers for Disease Control and Prevention [CDC] incandescent, white light-emitting diode [LED], and ultraviolet LED) caught greater numbers of mosquitoes compared with traps baited with yeast-generated CO2 and Biogents Sentinel™ traps (battery powered traps without light and passive box traps). However, diversity measures (species richness, evenness, and similarity) were consistently nearly equal among trap types. Arbovirus vectors were more common in forest locations, while malaria vectors were more common near human habitations. Location had a significant effect on trap effectiveness and mosquito diversity, with traps from forest locations having greater numbers and greater species richness, compared with traps set near human habitations. The results of this study will inform mosquito surveillance trap choices in remote regions of central South America, including regions with emerging tropical diseases, such and dengue and Zika virus.

The primary monitoring tools for collecting Culicoides midges (Diptera: Ceratopogonidae) are various models of light traps. To facilitate data comparison, four downdraught light traps were used in summer under South African conditions. These were the Onderstepoort trap [220 V, ultraviolet (UV)], the Rieb trap (12 V, UV) from France, the mini-CDC trap (6 V, UV) from the USA , and the Pirbright trap (220 V, white light) from the United Kingdom. Traps were deployed in three replicates of a 4x4 randomized Latin square design, so that treatment means were independent of any effects caused by the site or the occasion. Trapping was conducted during 12 nights in January 2008 (summer) and comprised 48 collections with 643,374 Culicoides midges collected. Eighteen different Culicoides species, of which only six were found in all four traps, were collected. All four traps indicated Culicoides imicola to be the most abundant species. Its abundance ranged from 91.8% (Rieb) to 95.0% (Onderstepoort). Statistically significant differences were found in the total number of Culicoides collected by each of these traps. The Onderstepoort trap (407,411) collected statistically significantly more midges than the CDC (167,794), Pirbright (39,128) or Rieb trap (32,041). Significant differences were also found between the traps in the parous rate, sex ratio and number of Culicoides midges compared to those of other insects. When comparisons were repeated in winter, when Culicoides numbers were relatively low compared to summer, the Onderstepoort trap still performed significantly better. All four traps, however, still captured Culicoides midges. In addition, the BG-sentinel mosquito trap, from Germany, was compared with the other four traps in two replicates of a 5x5 Latin square. These comparisons, which were done in spring, showed that the number of Culicoides midges collected with the BG-sentinel was not significantly different from that collected with the CDC trap. Although the Onderstepoort trap increased monitoring sensitivity in areas where vector abundances were low, results highlighted the notion that biases in trapping methods need to be evaluated and measured.

The production of shallots in Demak district in 2019–2023 tends to decline and become less stable, mainly due to plant-disturbing organism attacks. Using chemical pesticides to deal with plant-disturbing organisms can damage soil and cause pest resistance, requiring environmentally friendly technologies such as insect light traps. In adopting light trap technology, it is interesting to study farmers' decision-making processes and the factors influencing them. We conducted the study in January 2024 in Demak District, Central Java, Indonesia, using survey and purposive sampling methods to identify factors influencing farmers' decision-making when using light trap technology to increase shallot productivity. The sample consisted of 165 farmers using light traps, with primary and secondary data. We used Smart-PLS 3.0 software to analyze the variable measurement using a Likert scale (1–5). With path coefficients of 0.460, 0.199, and 0.398, respectively, the study indicated that internal variables, external factors, and innovation features much influenced farmers' choice to adopt light trap technology. With a path coefficient of 0.649, light trap adoption favored agricultural productivity, hence driving a 42.1% rise in output. The model was generally good, with significant predictive power, with a GoF score of 0.65617 and an R-square value of 0.633. Therefore, this study accepts the hypotheses and finds that internal, external, and innovative aspects influence farmers' decision to utilize light traps. This study adds essential theoretical and empirical data and clarifies how smallholder farmers promote sustainable agriculture by using light traps, therefore lowering the usage of chemical pesticides.

Full textAbstract:
For effective sampling of mosquitoes in malaria surveillance programmes, it is essential to include attractive cues in traps. With the aim of implementing a citizen science project on malaria vectors in rural Rwanda, a handmade plastic bottle trap was designed and tested in the field to determine its effectiveness in capturing adult Anopheles gambiae sensu lato, the main malaria vector, and other mosquito species. Carbon dioxide (CO2) and light were used as attractive cues. CO2 was produced by inoculating sugar with yeast and water. Light was emitted from a torch by light-emitting diodes (LEDs). Under field conditions in rural Rwanda, three handmade trap designs were compared to Centers for Disease Control and Prevention miniature light traps (CDC-LT) in houses. The trap baited with yeast produced CO2 and light caught the highest number of mosquitoes compared to the traps baited with light alone or CO2 alone. The number of An. gambiae s.l. in the handmade trap with light and CO2 was approximately 9–10% of the number caught with a CDC light trap. This suggests that about 10 volunteers with a handmade trap could capture a similar-sized sample of An. gambiae as one CDC-LT would collect. Based on these findings, the handmade plastic bottle trap baited with sugar fermenting yeast and light represents an option for inclusion in mosquito surveillance activities in a citizen science context.

Impact of climatic factors on pheromone and light trap catches of Helicoverpa armigera in sunflower crop and their correlation with various weather parameters was assessed during kharif 2012 and 2013 at the ZARS, UAS, GKVK, Bengaluru. Moth catches were recorded from August to December in both years, with peak activity observed in October and November. In 2012, pheromone traps recorded maximum catches during the 48th standard meteorological week (SMW), while light traps showed peak captures in the 40th SMW. In 2013, both traps recorded highest moth activity around the 41st SMW. Correlation and multiple linear regression analyses revealed significant relationships between trap catches and weather variables of corresponding week. In 2012, minimum temperature showed a strong negative correlation with pheromone trap catches (r = -0.671), while soil temperature was positively correlated with light trap catches (r = 0.624*). In 2013, minimum temperature again showed a significant negative correlation with both trap types. When data were pooled, multiple regression models indicated that weather parameters accounted for 79.80 and 63.39 per cent of the variability in pheromone and light trap catches, respectively.

The present investigation entitled, “Comparative efficacy of different power sources in light trap against major phototactic insect pest of rabi season” was carried out at the BSP (Breeder Seed Production) Farm, Adhartal, JNKVV, Jabalpur (MP) during rabi (mid-November 2022 to mid-April 2023) season 2022-2023.Four light traps design were used in study via. T1 – Solar light trap (with 40 cm funnel diameter, T2 – Solar light trap (50 cm funnel diameter), T3 – Electrical light trap (with 40 cm funnel diameter), T4 – Electrical (with 50 cm funnel diameter). All four light traps were operated every evening and collection was collected every morning for the duration of the investigation for 12 species viz., Helicoverpa armigera, Agrotis ipsilon, Creatonotus gengis, Spodoptera litura, Gryllus bamaculatus, Gryllotalpa orientalis, Nezara viridula, Amata cyssea, Asota ficus Perina nuda, Thysanoplusia orichalcea and Theretra oldenlandiae analysis daily data were combined into weekly totals, this data was subjected to analysis in paired and two sample t-test. In conclusion, electrical light traps were superior in terms of trapping efficacy compared to solar light traps for most of the species collected. The advantage of electrical light traps is in their ability to provide continuous illumination while the power is on, which ensures a higher attraction and capture rate of insects. On the other hand, solar light traps have limitations in providing consistent and sustained light throughout the night, potentially leading to reduced trapping efficiency.

AbstractThe mosquito sampling efficiency of CDC (Centers for Disease Control) miniature light traps hung adjacent to mosquito nets, was compared with that of both indoor and outdoor human-bait collections in ten villages in the Wosera area of Papua New Guinea. The most frequently collected anopheline in the matched indoor and light trap samples was Anopheles koliensis Owen, followed by A. punctulatusDönitz, A. karwari (James), A. farauti Laveran (sensu lato), A. longirostris Brug and A. bancroftii Giles. All species were much less frequent in the light traps than in landing catches. The hypothesis that the numbers of mosquitoes in light traps are proportional to human landing catches was examined using regression models that allowed for sampling error in both entomological measurements. Light traps under-sampled A. punctulatus and A. farautis.l. at high densities. The models indicated that the ratio of light trap to landing catch females of A. koliensis and A. karwari increased with increasing mosquito density. Light trap catches of A. longirostris were proportional to indoor landing rates but when outdoor landing rates were high this species was under-sampled by light traps. Numbers of A. bancroftii in light traps were found to be proportional to those in outdoor landing catches, but were negatively related to those attempting to bite indoors. Circumsporozoite positivity rates for both Plasmodium falciparum Welch and P. vivax (Grassi & Feletti) in A. punctulatus and A. farauti s.l. were significantly higher in light trap collections than in either indoor or outdoor landing catches, suggesting that light traps may selectively sample older mosquitoes of these species.

AbstractUnderstanding factors that influence attraction of tephritid fruit flies (Diptera: Tephritidae) to objects can lead to development of more sensitive traps for fly detection. Here, the objective was to determine if differences in attractiveness between two sticky yellow rectangle traps to western cherry fruit fly,Rhagoletis indifferensCurran, depend on ambient light intensity and direction. The translucent plastic Yellow Sticky Strip (YSS) was compared with the less translucent yellow cardboard Alpha Scents (AS). Flies were released inside a box or cage opposite a trap or traps illuminated from outside at different intensities to generate variable light passage. Regardless of type, the trap with greatest light passage was most attractive. When the same light intensity was shone on both traps, the YSS, which allowed greater light passage, was more attractive than the AS. When the light was inside a cage and shone onto the two traps in the same direction as approaching flies, the AS reflected more light and was more attractive. A field experiment generally supported light passage effects seen in the laboratory. Results suggest trap placement with respect to sunlight intensity and direction affects light passage and the attractiveness of yellow traps toR. indifferens.

AbstractRecords of hourly trap catches of Helicoverpa armigera (Hübner) in a light trap and two pheromone traps in Andhra Pradesh, India, were used to assess the influence of moonlight and weather on trap performance. The environmental factors that were considered were mean hourly temperature, relative humidity, wind speed and maximum hourly percentage moon illuminance. The mean number of adults caught per hour reached a peak at 03.00 h in the light trap and at 02.00 h in one of the pheromone traps. The environmental factors were not sufficiently severe to produce any marked activity thresholds, although zero catches were recorded in the light and pheromone traps on occasions when the mean hourly temperature was 11°C. Despite there being obvious relationships between hourly light and pheromone trap catches with temperature, relative humidity and wind speed, it was not possible to determine whether these were causally related or merely coincidental relationships. Some of the observed relationships could not be explained in terms of known physiological or behavioural characteristics of the insect. It was evident that the light trap performance was influenced by the level of moon illuminance because this affected both the timing and size of the peak catch.

Insect traps are vital component of many entomological programs for detection and monitoring of insect populations. We equipped yellow (YC), blue (BC) sticky card (BC) with 530 nm lime green (LED-YC) and 470 nm blue (LED-BC) light-emitting diodes, respectively that increased trap catches of several insect pests. The LED-YC traps caught 1.3, 1.4, 1.8, and 4.8 times more adult greenhouse whitefly Trialeurodes vaporariorum (Westwood), sweetpotato whitefly Bemisia tabaci (Gennadius) biotype B, cotton aphids Gossypium hirsutum (L.), and fungus gnats Bradysia coprophila (Lintner), respectively, compared with standard YC traps. The LED-YC traps did not catch more Eretmocerus spp. than the standard YC traps. Eretmocerus spp. are important B. tabaci parasitoids used in greenhouse biological control programs. For whitefly control in greenhouse the 530 nm lime green LED equipped plastic cup trap designed by Chu et al. (2003) is the better choice than LED-YC trap because it catches few Eretmocerus spp. and Encarsia spp. whitefly parasitoids released for B. tabaci nymph control. The LED-BC traps caught 2.0-2.5 times more adult western flower thrips Franklinella occidentalis (Pergande) compared with the standard BC traps.

The CDC light trap has been the standard used by mosquito control programs to conduct mosquito and arbovirus surveillance. For the last two decades, this trap has been used with little to no modifications to its original design. Recently, new traps that utilize different light sources, modified designs, and attractants have been developed and evaluated against the CDC light trap. A semi-field and field comparison of the Dynatrap® (Model DT2000) against the CDC light trap was conducted at Anastasia Mosquito Control District. The DT2000 varies from the CDC light trap with a UV light, trapdoor/fan mechanism, and Atrakta lure which is a combination of lactic acid, ammonia, and hexanoic acid. Overall, the DT2000 collected 56% (327/600) of the Ae. aegypti released in the semifield cage, compared to 18.5% (111/600) collected by the CDC light traps. These findings suggest that the DT2000 outperformed the CDC light trap in collecting Ae. aegypti. In the field, the DT2000 collected nine target mosquito species while the CDC light trap collected four target species. The DT2000 averaged 109 ± 97.46 mosquitoes and the CDC light trap averaged 8 ± 4.64 mosquitoes. The DT2000 presented functional limitations in the field as an electrical outlet was required. Study findings suggest that where an electrical outlet is available, the DT2000 may be an alternative to the CDC light trap for mosquito surveillance.

Till today, the light traps in Nepal are found using with traditional type, which have not being recognized internationally. These light traps were of low efficiency for trapping insects as compared to black light trap (BLT). The black light tube (F10T8/BL) was used in newly constructed trap at National Maize Research Program (NMRP), Rampur, Chitwan, Nepal. Both traps were installed at the maize experimental field at NMRP during February to October, 2017. Data on insect numbers were recorded once in a week from dusk to down in two different days to minimize the light effects of each others. The total number of insects trapped in BLT was 2804 as compared to 868 in traditional light trap (TLT). Among the insect orders, Coleopterans were mostly trapped in BLT followed by Lepidopteron and Hemipterans. The results showed that the trapping efficiency of BLT was three fold higher than that of TLT. Therefore, black light trap was highly effective monitoring tool and its field applications are expected to be commercialized.

Tuta absolute was a quarantine pest in Iran that has been recorded for the first time in 2009. The most conventional methods for control of this pest in Iran are chemical methods and mass trapping, although the efficiency of the latter method is not clear. In 2013, the efficiency of three common types of solar light traps with and without sex pheromone, along with water pan pheromone traps for control, were investigated. The experiment was performed in a randomized complete block design within in a tomato field. The treatments were Behroyan light trap (BL), Zist bani light trap (ZL), Russell light trap (RL), BL + pheromone, ZL+ pheromone, RL+ pheromone and water pan pheromone trap (WPT). Traps were checked weekly and the number of captured tomato leaf miner (TLM), Noctuid moths, Chrysopa sp., Coccinella septempuctata and Syrphid flies were counted. Mean weekly capture of TLM in BL, ZL and RL traps without sex pheromone were 9.11 ± 1.16, 4.94 ± 0.24 and 1.66 ± 0.7, while within traps sex pheromone were 54.72 ± 11.8, 42.05 ± 6.47, 39.02 ± 2.82, respectively. The mean weekly capture of Noctuid moths in the traps without pheromone were 16.92 ± 1.39, 25.39 ± 0.57, 1.49 ± 0.27 and with pheromone were 21.04 ± 1.72, 28.09 ± 0.95, 2.76 ± 1.39, respectively. Mean weekly capture of TLM and Noctuid moths in WPT traps were 47.13 ± 3.06 and 0.73 ± 0.27, respectively. The total attracted numbers of predators by the three light traps were not significant. In conclusion, traps baited sex pheromone (especially BL and ZL) could be used as eco- friendly tools for mass trapping of TLM and some key Noctuid moth pests in isolated tomato fields.

Mosquito monitoring traps (i.e., CDC light traps) are crucial tools for basic vector ecology research, risk assessment, and vector control programs. Unfortunately, they are expensive which is often an issue in projects conducted in developing countries. Therefore, it would be desirable to have reliable but inexpensive alternatives based on existing consumer products. We compared an off-the-shelf DynaTrap (model DT160, CCFL tube 365 ± 3 nm UV) modified to fit a CDC trap collection bag and to use a 12V power supply, with two commonly used CDC traps: CDC Miniature Light Trap Model 512 (incandescent light, 6 Volt) and CDC Miniature Downdraft Blacklight (UV) Trap Model 912 (4-Watt blue-black-light tube, 12 Volt), in different ecological settings in southwest (Kenieroba) and northwest (Nioro du Sahel) Mali, West Africa. In northwest Mali, the modified DynaTrap caught a mean of 20.67 ± 2.8 females and 5.38 ± 1.0 male Aedes aegypti which was 16.55% and 10.78% more, respectively, than the CDC incandescent trap (control). The DynaTrap caught a mean of 29.75 ± 2.8 female and 17.92 ± 3.5 male Culex quinquefasciatus. which was 47.76% and 20.70% more than the control CDC incandescent trap. The DynaTrap caught a mean of 2.46 ± 0.5 females and 1.63 ± 0.6 males and 10.16% and 2.45% more female and male An. gambiae s.l., respectively, than the CDC incandescent trap. Trap and catch means were lower at the southwest Mali site. However, trap catch proportions by sex were similar to those in the northwest. The modified DynaTrap outperformed both CDC monitoring traps for less than one third of the cost including the cost of the DynaTrap modifications.

The paper is devoted to the analysis of existing options of under-reactor melt traps, designs and disadvantages of these traps. A variation of its own under-reactor melt trap with a heat-resistant composite coating with a fluidized bed is proposed. The description of facility for experimental studies of the heat-resistant composite coating with the fluidized bed is presented. The results of a thermal calculation of the variation of the under-reactor trap with fluidized bed melt are presented. Thermal calculations showed that an increase in the average temperature of the melt is less intense in the model of an under-reactor trap with a fluidized bed, due to heat removal from the corium to the metal to complete the phase transition.

<p>Stored product insect can cause consumer rejection and economic loss due to quality concerns and phytosanitary regulation. Insect traps have been regularly used as a control method, however its effectiveness on controlling stored copra meal insect pests is not yet known.This study was carried out to compare the effectiveness of three types of insect traps for detection of insect pests of copra meal.The three types of insect traps were pitfall trap, probe trap, and ultraviolet (UV) light trap (blacklight and LED-light emiting diodes). Research was conducted at Laboratory of Entomology SEAMEO BIOTROP, Bogor and two storage facilities of copra meal in North Sulawesi. Laboratory experiment was conducted using completely randomized design with two factors and four replications. The first factor was the types of insect traps (pitfall trap, probe trap, and probe trap with UV LED) and the second factor was insect species (<em>Lasioderma serricorne</em> (Herbst) and <em>Tribolium castaneum </em>(Fabricius)). The experiment at storage facilities was conducted with nested block design where the insect species trapped were nested in the insect traps. The result of laboratory experiment showed that the probe trap captured more insects (30.4%) significantly higher than pitfall trap (17.1%), however there was no significant difference of number of insects trapped in probe trap with and without UV LED. In addition the probe trap captured more <em>T. castaneum</em> and <em>Tenebroides mauritanicus</em> than other type of insects trap, but probe trap with UV LED was more effective to detect <em>L. serricorne</em> and <em>Necrobia rufipes</em> (Fabricius) in the stored copra meal.</p>

AbstractOrchestes fagi (Linnaeus) (Coleoptera: Curculionidae) is a pest of beech trees (Fagus sylvatica Linnaeus; Fagaceae) in Europe that has recently become established and invasive on American beech (Fagus grandifolia Ehrhart) in Nova Scotia, Canada. We tested the effects of trap type, trap colour, trap height, and lure on the numbers of O. fagi captured per trap with the objective of developing a survey tool to monitor the weevil’s spread. We captured O. fagi in significantly greater numbers on yellow, green, or white traps than on light blue, dark blue, or red traps. There were no significant interactions between trap colour and trap design. Sticky triangular prism traps caught significantly more O. fagi than did nonsticky intercept traps regardless of colour. No effect of trap height was observed. Mean catch of O. fagi was significantly greater on yellow sticky triangular prism traps than on commercially sourced yellow sticky cards. Baiting yellow, green, or white sticky prism traps with the host volatile 9-geranyl-p-cymene did not increase catch of O. fagi. Our results suggest that yellow, green, or white sticky prism traps are a useful tool for detecting O. fagi adults and monitoring the spread of this species in Canada.

Solusi yang ditawarkan oleh tim PKM yaitu menerapkan teknologi light trap yang terbukti efektif mengendalikan hama pada tanaman padi. Metode yang digunakan pada kegiatan ini adalah 1) penyuluhan berkenaan dengan pengenalan dan perawatan alat light trap dan 2) pengamatan langsung dilapangan untuk melihat jenis-jenis hama yang terperangkap pada light trap. Evaluasi efektivitas light trap dilakukan dengan metode partisipatif dimana masyarakat ikut melakukan pemantauan hama yang terperangkap pada setiap jenis perangkap dan melakukan perhitungan penghematan biaya produksi. Pemasangan light trap selama satu bulan dapat menekan penggunaan jenis pestisida sebesar 83,86% dengan penghematan biaya pengendalian hama sebesar Rp. 1.325.000/musim tanam, berdasarkan pengamatan diketahui bahwa light trap berhasil menangkap 7 jenis hama (881 ekor) dengan proporsi tertinggi pada jenis cahaya ungu (49%).Abstract: The implementation of community service is carried out to answer farmers' problems in the local rice cultivation technique "Banga Laka" which is indicated to use excess synthetic pesticides, besides that farmers do not know the types of pests that attack rice plants so that they tend to use pesticides not on target. The solution offered by the PKM team is to apply light trap technology which is proven to be effective in controlling pests on rice plants. The methods used in this activity are 1) counseling regarding the introduction and maintenance of light traps and 2) direct observation in the field to see the types of pests trapped in light traps. Evaluation of the effectiveness of light traps is carried out using a participatory method where the community participates in monitoring pests trapped in each type of trap and calculating production cost savings. Installing a light trap for one month can reduce the use of pesticides by 83.86% with a pest control cost savings of Rp. 1.325.000/planting season, based on observations it was known that the light trap managed to catch 7 types of pests (881 individuals) with the highest proportion in the type of purple light (49%).

AbstractThe efficiency of modified CDC miniature light-traps for sampling adult mosquitoes was evaluated in comparison with indoor resting, outdoor resting, indoor man-landing and outdoor man-landing collections in the hilly district of Koraput, Orissa, India. Overall, light-traps captured 78% of adult mosquitoes collected by all methods. Of the 16 anopheline species recorded in the study area, light-traps effectively sampled 13, contributing about 72% of the total anophelines collected by all methods. Light-traps also caught a large number of female Culex vishnui Theobald (96%). As fully-fed mosquitoes were predominant (82%) and caught alive, light-traps can be used to catch large numbers of vector mosquitoes for studies on vector prevalence, distribution, vector incrimination and also for laboratory bioassays. Light-trap and indoor resting collections revealed similar seasonal trends in numbers of Anopheles culicifacies Giles, A. fluviatilis James, A. jeyporiensis James, A. vagus Doenitz, and A. splendidus Koidzumi. Age-structure of the samples did not vary significantly between the two methods. Light-traps could be used as an alternative to daytime indoor resting collections to monitor the seasonal fluctuations in the abundance and parity rates of these species. The light-trap collections correlated with indoor and outdoor man-landing collections of A. jeyporiensis and the outdoor man-landing collections of A. maculatusTheobald in measuring seasonal trends. Light-trap collections can thus be used as a substitute for man-landing collections of A. jeyporiensis and A. maculatus.

Rice striped stem borer damage the rice crops from the seedling to crop maturity and in sever infestation result in white ear head during the reproductive stage and dead heart during the tillering stage, which causes huge yield loss up to 60.0 %. The most crucial and essential component of the IPM strategy is pest monitoring, which is consistently evaluate the population and crop damage. Thus, the present research was performed to monitor and control the RSSB by using the different trapping devices in rice filed. Attraction in different trapping devices revealed that initially adult were caught during the first week of August and increased subsequently weeks in all trapping devices up to the October. Further data showed overall maximum seasonal adult population (195.30±19.25) was caught by pheromone traps followed by light traps (101.45±14.58), yellow color sticky traps (97.50±13.25) and yellow water pan trap (53.50±09.25), respectively. Furthermore, data exhibited the highest trapping efficiency (43.71%) was observed by the installation of pheromone traps followed by light traps (22.61%), yellow color sticky traps (21.70%) and water pan trap (11.97%), respectively. In addition, impact of the treatments was observed by calculate the crop damage symptoms and minimum crop damages i.e white ears and dead hearts (09.94±1.25%) and (09.39±1.10%) were recorded pheromone traps followed by light traps (12.59±1.25%) and (11.88±1.62%), yellow color sticky trap (YCST) (17.89±1.89%) and (17.48±2.10%), and yellow water pan trap (YWPT) (25.64±2.46) and (22.81±3.23), control (42.68±7.23) and (39.03±07.12) were recorded, respectively. Furthermore, results showed the highest average yield (4865.00 kg/haˉ1) was obtained in the plots where pheromone traps were installed, followed by light traps (4608.00 kg/haˉ1), YCST (4230.50 kg/haˉ1), YWPT (4205.0 kg/haˉ1) and in control (4037.60 kg/ haˉ1), respectively. Based on the present findings, highest adult attraction, lowest crop damage and significant high yield, thus, pheromone and light traps are the convenient tools to control adults of rice striped stem borer in rice.

Only one such trap, the Furvela tent-trap, does not require an ‘entry’ behavior on the part of the mosquito. It remains the cheapest and lightest tent-trap described. It takes less than two minutes to install and is the only trap that uses readily available components. Here we describe recent modifications to the trap, which make it even easier to set up in the field, provide a standard operating procedure (SOP) and describe some recent experiments examining the effect of the addition of light and door placement to working of the trap. The trap provides the closest approximation to CDC light-traps, widely used to collect indoor biting mosquitoes. This enables the effect of both indoor and outdoor interventions on mosquito density and behavior to be determined.

ABSTRACT Mosquito surveillance is the cornerstone for determining abundance, species diversity, pathogen infection rates, and temporal and spatial distribution of different life stages in an area. Various methods are available for assessing adult mosquito populations, including mechanical trap devices using different forms of attractant cues (chemical and visual) to lure mosquitoes to the trap. So-called “light traps” use various electromagnetic wavelengths to produce a variety of visible spectral colors to attract adult mosquitoes. However, this type of trapping technology has not been widely used in Thailand. This study compared the efficacy of 4 light-emitting diodes (LEDs) (blue, green, yellow, and red) and 2 fluorescent (ultraviolet [UV] and white) lights for collecting mosquitoes in urban Bangkok. Using a Latin square experimental design, 6 light traps equipped with different lights were rotated between 6 trap site locations within the Kasetsart University (KU) campus. Each location received 6 replicate collections (6 consecutive trap-nights represented 1 replicate) over 36 collection nights for a total of 216 trap-nights. Traps were operated simultaneously (1800 to 0600 h), with captured mosquitoes removed at 3-h intervals. In total, 2,387 mosquitoes consisting of 11 species across 5 genera (Aedes, Anopheles, Armigeres, Culex, and Mansonia) were captured. Collectively, Culex species represented the predominant group sampled (2,252; 94.4%). The UV light source captured 1,544 (64.7%) of the total mosquitoes collected, followed by white 389 (16.3%), with the 4 LED sources collecting between 6.8% (blue) and 1.9% (yellow). Traps equipped with UV light were clearly the most effective for capturing nocturnally active mosquito species on the KU campus.

Optical tweezers are designed to trap nano- and micro-scale particles. Once trapped, it is possible to move the particles but this requires complex mechanical adjustments to the optical system. In this paper, an easier way to trap and move multiple particles simultaneously is proposed, that uses a digital mirror-array and freeform micro-lens-array to generate several steerable optical traps inside a light-field.

Abstract A dynamic holographic optical trap uses a dynamic diffractive optical element such as a liquid crystal spatial light modulator to realize one or more optical traps with independent controls. Such holographic optical traps provide a number of flexibilities and conveniences useful in various applications. One key requirement for such a trap is the ability to move the trapped microscopic object from one point to the other with the optimal velocity. In this paper we develop a nematic liquid crystal spatial light modulator based holographic optical trap and experimentally investigate the optimal velocity feasible for trapped beads of different sizes, in such a trap. Our results show that the achievable velocity of the trapped bead is a function of size of the bead, step size, interval between two steps and power carried by the laser beam. We observe that the refresh rate of a nematic liquid crystal spatial light modulator is sufficient to achieve an optimal velocity approaching the theoretical limit in the respective holographic trap for beads with radius larger than the wavelength of light.

We measured the efficiency of floating minnow-traps (Gee traps), unbaited or baited with red, green, blue, or white chemical light sticks (glowsticks) to trap large, predaceous, aquatic beetles (Coleoptera) and bugs (Hemiptera) in 50 fresh water, lentic systems in northern Nova Scotia, Canada. Standard minnow-traps buoyed with Styrofoam® floats were set overnight in a variety of freshwater habitats, including ponds, marshes, bog pools and vegetated lake margins throughout the ice-free seasons over three years, for a total of 695 trap-nights. Giant Water Bugs (Lethocerus americanus) were captured with equal frequency in traps baited with any colour glowstick and in unbaited controls. Brown Waterscorpions (Ranatra fusca) were significantly more abundant in light-baited traps than in dark controls, and showed a strong preference for green lures over other colours. The large, Vertical Diving Beetle Dytiscus verticalis was caught significantly more than expected with white or red lures and significantly less with green or blue lures; males were caught even less often with green or blue lures than in unbaited controls. Our results reveal a heretofore unknown component of the biology of these insects, and suggest a novel method for simple and effective sampling of aquatic insects in still waters.Keywords: light; trapping; phototaxis; aquatic insects; colour

There are two types of shallot planting systems in Sudimoro Village: the conventional system and the Automatic solar blue light trap system. The conventional system is planting shallots with the general treatment being to apply only synthetic chemical pesticides, while the Automatic solar blue light trap system is planting shallots by applying synthetic chemical pesticides and applying Automatic solar blue light traps. The purpose of this study was to compare the conventional system of shallot farming and the automatic solar blue light trap application system in Sudimoro Village. The population of this study was all shallot farmers in Sudimoro Village, which amounted to 9 farmers, consisting of 5 conventional farmers and 4 farmers applying Automatic solar blue light traps. This study uses a quantitative descriptive approach. The results of this study can be seen that the value of the R/C ratio of the conventional system is 1.33, while the system applies the Automatic solar blue light trap 3.36. These results indicate that both shallot farming systems are feasible to cultivate. While the value of the B/C ratio for the conventional system is 0.33, while the system applies the Automatic solar blue light trap 2.36, these results indicate that the shallot farming in Sudimoro Village, the conventional system is not feasible to continue, while the system applying the Automatic solar blue light trap is feasible to be continued.

Full textAbstract:
Thermally stimulated current spectroscopy (TSC) has been applied to characterize deep traps in high-purity semi-insulating 6H-SiC substrates. By using above bandgap to sub-bandgap light for illumination at 83 K and different applied biases, at least nine TSC traps in the temperature range of 80 to 400 K can be consistently observed. It is found that TSC peaks for T < 130 K are significantly affected by light and some peaks are strongly enhanced by the applied bias. Measured trap activation energies range from 0.15 eV to 0.76 eV. Theoretical fittings of selected traps give more accurate trap parameters. Based on literature results connected with deep traps in conductive 6H-SiC, the origin of these TSC traps is discussed.

Population control of small sucking insects has been challenging, and alternative control methods are constantly being sought. Visual traps have long been used to monitor and control pests. Colored sticky cards are widely used for diurnal pests, but their effects are influenced by environmental light conditions. Artificial light traps are mostly used for nocturnal pests. Here, we explored and evaluated light-emitting diode (LED) traps for the monitoring and control of small diurnal sucking insects using greenhouse tests targeting the greenhouse whitefly Trialeurodes vaporariorum. We tested the trapping efficacy of the LED water pan trap, assessed the most attractive LED light and analyzed its efficacy under different weather conditions. The results showed that the LED water pan trap was too inefficient to be useful. Green LEDs were more attractive than yellow LEDs, UV LEDs and green-UV combinations. Regardless of sunny or cloudy conditions, the green LED trap caught more than twice the number of whiteflies than the yellow sticky card alone under summer shading conditions. Our study suggests that LED traps have a significant field application value in whitefly mass trapping and may also be efficient for other diurnal insects. The design of LED traps specific for diurnal insects is discussed.

Full textAbstract:
Device structure, light source height, and climatic factors can potentially affect the catching of target pests in light traps. In this study, the installation of an anti-escape cover in a newly designed light trap significantly increased the number of catches of tea leafhoppers, Empoasca onukii, an economically significant pest of tea gardens, and it prevented 97.95% of leafhoppers from escaping. A series of assessments were performed in the field and showed that the optimal trapping window of the light trap was between 1.5 and 2.5 h (2 ± 0.35 h) after sunset, and the starting time of the window was positively correlated with the sunset time. The number of leafhopper catches decreased sharply when the height of the light source was above the flight height range of E. onukii adults. The height of the light source was optimal between 20 and 40 cm above the tea canopy. The efficacy of the light traps for capturing leafhoppers decreased in the autumn peak period. High numbers of leafhopper catches by the newly designed light trap in the summer could reduce E. onukii population sizes in the autumn. Overall, the newly designed light trap can be used to reduce E. onukii adult populations in tea gardens.

Full textAbstract:
Lasioderma serricorne (F.) commonly called cigarette beetle is a cosmopolitan, polyphagous and major insect pest of stored turmeric that is known to be resistant to the phosphine fumigation. Practical studies were carried out to assess the efficacy of TNAU UV-Light Trap in mass trapping of L. serricorne during the pre and post fumigation periods and its role in phosphine resistance management in L. serricorne in turmeric warehouses. Adult beetles collected from UV light traps before and after fumigation were tested through bioassay on the basis of the response of adults to discriminating concentration of 0.07mg L -1 for 24 h exposure period using modified FAO method (FAO, 1975). The results of the present study showed that, the mean number of adults caught per trap/day before and after fumigation ranged from 52.7 to 83.5 and 9.6 to 18.2 beetles per light trap, respectively. The bioassay results showed that, the phosphine resistance level in L. serricorne collected from UV- Light traps ten days before and after fumigation ranged from 52.85 to 65.37 and 68.24 to 76.53 per cent, respectively. Further, the beetles caught in large numbers in light traps during the post fumigation period were found to be more resistant to phosphine than the pre fumigation population. Hence, UV- Light trap can be used as one of the resistance management strategy for phosphine resistance in L. serricorne in turmeric warehouses since mass trapping of L. serricorne was recorded in TNAU- UV Light trap during pre and post fumigation periods.

(Uploaded by Plazi for the Bat Literature Project) Collecting information on bat prey availability usually involves the use of light traps to capture moths and flies that constitute the main prey items of most insectivorous bats. However, despite the recent awareness on the adverse effects of light on bats, little is known regarding the potential impacts of light trapping on the bat sampling outcomes when passive acoustic sampling and light trapping are implemented simultaneously. Using a before–after experimental design that involved the installation of a 6 W actinic light trap 1 m away from the bat detector, we tested the predictions that (1) slow-flying bat species will be less active when the light trap is present, while the opposite will be true for fast-flying species; and (2) bat species richness will be lower at lit conditions compared to dark ones. Our results suggest that the use of light traps in combination with bat detectors may considerably influence the outcomes of acoustic sampling. Although the activity of fast-flying bat species did not differ between the two treatments, we found that the activity of slow-flying ones such as Rhinolophus ferrumequinum and Rhinolophus hipposideros decreased significantly at lit conditions. Furthermore, we recorded fewer bat species when the light trap was deployed. To overcome this issue, we strongly recommend either (1) placing light traps at a considerable distance from bat detectors; or (2) using light traps during the night that follows the bat sampling if sampling needs to be at the same position; or (3) deploying non-attractant insect traps such as Malaise traps if Lepidoptera is not the main order targeted.

Eastern equine encephalitis virus (EEEV) is a highly dangerous alphavirus vectored by multiple mosquito species in the United states. Vector surveillance and control is used to prevent the spread of EEEV, so highly efficient and attractive traps are needed to accurately assess mosquito abundance. Mosquitoes can be captured in various physiological states (host-seeking, gravid, resting, etc.), depending on what trap type is used. this study analyzed 6 trap types to determine which captured the most EEEV vectors in saint Johns county. the trap types analyzed were the biogents sentinel trap, centers for Disease control (cDc) Light trap, the sentinel Mosquito Arbovirus capture Kit, Mosquito Magnet X trap, cDc resting trap, and gravid traps. For the gravid traps, two different infusions were tested: hay infusion and cattail infusion. Aedes atlanticus Dyar and Knab was the most abundant EEEV vector captured in this study. Other EEEV vectors collected were Aedes vexans (Meigen), Culex erraticus (Dyar and Knab), and Culex nigripalpus theobald. bG traps caught the highest abundance of EEEV vectors (1520 ± 743) compared to all the other trap types analyzed. Despite capturing multiple EEEV vectors during the testing period at the chosen site, Culiseta melanura (coquillett) and Coquillettidia perturbans (Walker) were never captured.

Pesisir Barat is one of the locations that has a great opportunity for capture fisheries activities in Lampung. Bubu is a passive fishing gear, made of thick steel frames, woven nets with small openings. Bubu is usually used to catch fish or other small crustaceans, by luring them to swim and trapping them inside. In this study, we used a light attractor as bait. Thus, increasing the effect of the trap. It exploits the phototactic behavior exhibited by many fish species, which are attracted by light itself, or preys on light-attracted phototactic invertebrates. In this study we used two kinds of traps. First, those with light attractors, then those without light attractors. The purpose of this study was to determine the composition of the catch and comparing the result of both traps. This research was carried out from June to July 2022 with an estimated water depth of ±4-6 meters. The trap size is 120 cm x 70 cm x 80 cm. The composition of the catch on trap fishing gear consisted of several types of catch including blue-spotted grouper, red snapper, kuniran, baronang, cuttlefish, shrimp, squid and octopus. The result are quite different. The traps with LEDs having more result compared to traps without LED modifications.
