Abstract:

The Australasian lycosid genus Venatrix Roewer, 1960, with Venator fuscus Hogg, 1900 as type, is reinstated and redefined to include 22 species as follows: Venatrix funesta (C. L. Koch, 1847), comb. nov. (= Venator fuscus Hogg, 1900; syn. nov.); V. penola, sp. nov.; V. australiensis, sp. nov.; V. roo, sp. nov.; V. mckayi, sp. nov.; V. koori, sp. nov.; V. archookoora, sp. nov.; V. pictiventris (L. Koch, 1877), comb. nov.; V. hickmani, sp. nov.; V. allopictiventris, sp. nov.; V. speciosa (L. Koch, 1877), comb. nov. (= Lycosa mayama McKay, 1976; syn. nov.); V. esposica, sp. nov.; V. pseudospeciosa, sp. nov.; V. brisbanae (L. Koch, 1878), comb. nov.; V. forsteri, sp. nov.; V. lapidosa (McKay, 1974), comb. nov.; V. fontis, sp. nov.; V. furcillata (L. Koch, 1867), comb. nov.; V. arenaris (Hogg, 1905), comb. nov.; V. pullastra (Simon, 1909), comb. nov.; V. goyderi (Hickman, 1944), comb. nov. (= Lycosa howensis McKay, 1979; syn. nov.); and V. hoggi, sp. nov. Hogna albosparsa (L. Koch, 1876) is considered nomen dubium. Venatrix comprises species mainly found in temperate forests and open areas near watercourses, lakes and springs. Notes on the distribution together with maps, zoogeography and subfamilial placement of Venatrix are given. A solution is proposed to resolve confusion over the dates of some of Roewer’s publications.

Abstract:

With over 2400 species in 123 genera, Lycosidae is one of the largest spider families (WSC 2017). For over two hundred years, the type genus Lycosa Latreille, 1804 have accumulated large-sized wolf spiders from all over the world. Thus, with 218 nominal species, this genus is distributed in all zoogeographical regions (WSC 2017). Almost none of the species currently classified in Lycosa appear to be related to the type species—L. tarantula (Linnaeus, 1758); hence, the genus is polyphyletic and should be divided into several genera. This process has been already started; for example, in Australia and New Zealand where many of large wolf spiders have been removed from Lycosa (Roewer 1955, 1959, 1960; Vink 2002; Framenau & Baehr 2016). Also, some Holarctic, Neotropic and Afrotropic species were transferred from Lycosa to other genera (for a complete list of references see WSC 2017). In the Palaearctic, Lycosa is represented by 60 species (WSC 2017) and remains almost unrevised. From the southern Palaearctic, Saharo-Gobian desert region (Yemel’yanov 1974), 36 species of Lycosa have been recorded to date, 6 of which are poorly described (WSC 2017).

Abstract:

A large burrowing wolf spider, Lycosa macrophthalma sp. nov., is described from the holotype female from central Iran. The new species can be easily distinguished from all congeners by the presence of anterior epigynal hoods and a protrusion between their edges and the septum. Lycosa macrophthalma sp. nov., L. aragogi Nadolny et Zamani, 2017, L. piochardi Simon, 1876, L. praegrandis C.L. Koch, 1836, and L. tarantula (Linnaeus, 1758) have a similar conformation of the endogyne and represent diagnostic characters of the genus Lycosa Latreille, 1804 sensu stricto.

Abstract:

The Australian wolf spider (Lycosidae Sundevall, 1833) genus Tasmanicosa Roewer, 1959 with Lycosa tasmanica Hogg, 1905 as type species is revised to include 14 species: T. godeffroyi (L. Koch, 1865), comb. nov. (= Lycosa tasmanica Hogg, 1905, syn. nov.; = Lycosa zualella Strand, 1907, syn. nov.; = Lycosa woodwardi Simon, 1909, syn. nov.); T. fulgor sp. nov.; T. gilberta (Hogg, 1905) comb. nov.; T. harmsi sp. nov.; T. hughjackmani sp. nov.; T. kochorum sp. nov.; T. leuckartii (Thorell, 1870), comb. nov. (= Lycosa molyneuxi Hogg, 1905, syn. nov.); T. musgravei (McKay, 1974) comb. nov.; T. phyllis (Hogg, 1905) comb. nov. (= Lycosa stirlingae Hogg, 1905, syn. nov.); T. ramosa (L. Koch, 1877), comb. nov.; T. salmo sp. nov.; T. semicincta (L. Koch, 1877) comb. nov.; T. stella sp. nov.; and T. subrufa (Karsch, 1878) comb. nov. Within the Australian wolf spider fauna, the genus Tasmanicosa can be diagnosed by the distinct pattern of radiating light and dark lines forming a “Union-Jack” pattern on the carapace. Male pedipalp morphology identifies the genus as part of the subfamily Lycosinae Sundevall, 1833 due to the presence of a transverse tegular apophysis with dorsal groove guiding the embolus during copulation. However, genital morphology is variable and a synapomorphy based on male pedipalp or female epigyne morphology could not be identified. Members of Tasmanicosa are comparatively large spiders (body length ca. 12–30 mm), that build a shallow burrow, which is sometimes covered with a flimsy trapdoor. Species of Tasmanicosa are largely a Bassian faunal element with preference for open woodlands and/or floodplains, although some species can be found into the semi-arid Australian interior. Two Australian wolf spider species may represent Tasmanicosa based on their original descriptions, but due to immature types in combination with the somatic similarities of all Tasmanicosa species, cannot be identified with certainty. They are therefore considered nomina dubia: Lycosa excusor L. Koch, 1867 and Lycosa infensa L. Koch, 1877. The type species of Orthocosa Roewer, 1960 is transferred to Tasmanicosa; however, in order to prevent some non-Australian wolf spiders in the genus Orthocosa to be transferred into Tasmanicosa, which is considered endemic to Australia, we here place these species into more appropriate genera based on their original descriptions pending a future revision of these species: Arctosa ambigua Denis, 1947 comb. reval.; Alopecosa orophila (Thorell, 1887) comb. nov.; Hygrolycosa tokinagai Saito, 1936 comb. reval. Orthocosa sternomaculata (Mello-Leitão, 1943) is considered a junior synonym of Hogna birabeni (Mello-Leitão, 1943) comb. nov.

Full text

Abstract:

Compared to other cultivar lychees, volume density of Feizixiao lychee was higher due to serious shrinkage during freeze-drying (FD). Guiwei lychee and Nuomici lychee were used for comparison in order to illuminate the reason of the aforementioned phenomenon. Lower prefreezing temperature could not improve the volume density of Feizixiao lychee. Microstructure results show that pulp cell of Feizixiao lychee (tail) was smaller and more compact than Guiwei and Nuomici lychee pulp cell. In addition, there is a membrane around the surface of Feizixiao lychee pulp. And the microstructure of Feizixiao lychee tip pulp cell is different from tail pulp cell. Membrane and tip pulp cell are both smaller and more compact than tail pulp cell. These structure differences hinder the moisture removing of Feizixiao lychee during FD. Removing the membrane and tip pulp could not improve the volume density of Feizixiao lychee. Ultrasound treatment for 30 min could significantly enhance the volume density of Feizixiao lychee.

Abstract:

Twenty-six juvenile wolf spiders belonging to each of three groups, Lycosa carbonelli and L. thorelli and their experimentally obtained hybrids, were raised; 11, 7, and 17, respectively, survived to the adult stage. Lycosa carbonelli averaged 8.1 moults to reach the adult stage, L. thorelli 9.7, and hybrids 8.6; no significant differences were observed between the sexes. Lycosa carbonelli required more time than the other groups between emergence from the egg sac and the first moult. The durations of the intermoult periods and total development were not significantly different among groups. In L. carbonelli and the hybrids, the duration of the intermoult periods increased during development. In L. thorelli the duration of the intermoult periods was fundamentally modified in relation (inverse) to temperature. The life-span of the adults was similar in the three groups: females generally lived longer than males. The initial delay in the development of L. carbonelli would contribute to a decrease in competition of small juveniles with those of L. thorelli, although adults would compete more. The characteristics of hybrids tended to be intermediate, though closer to those of L. carbonelli.

Abstract:

In this study, authors aim to figure out the effectiveness of the food and drink process in the case of making lychee juice and lychee-tea combination fruit juice in a tropical country such as Vietnam, via a business model, with inputs, process, and outputs. We used scientific methods such as: qualitative analysis, synthesis and inductive methods, with description and explanatory methods. We also build a typical quantitative business model to measure profits of our lychee project. We propose to buy lychee (red lychee) with black tea from Northern provinces such as Thai Nguyen city, Hai Duong and Ha Giang provinces, etc. Then we can have a business model of making fruit juice from lychee products (red lychee with green or black tea). This will shows effectiveness of delicious food and drink making from good agricultural products of Vietnam. Last but not least, we emphasizes positive and healthy aspects of lychee products and lychee fruit juice in our country, Vietnam. And also roles of banks in project financing is also a good way to support microfinancing for star-ups and our business model.

Abstract:

The Australasian wolf spider genus Artoria, with A. parvula Thorell, 1877 as type species, is revised in part. In addition to A. parvula (=A. luwamata Barrion &amp; Litsinger, 1995, new synonymy), recorded from the Philippines and Indonesia, and A. palustris Dahl, 1908 from Papua New Guinea, it includes the Australian A. albopedipalpis, sp. nov., A. avona, sp. nov., A. cingulipes Simon, 1909, A. flavimanus Simon, 1909 (=Lycosa neboissi McKay, 1976, new synonymy), A. howquaensis, sp. nov., A. lineata (L. Koch, 1877), A. mckayi, sp. nov., A. quadrata, sp. nov., A. taeniifera Simon, 1909, A. triangularis, sp. nov., A. ulrichi, sp. nov. and A. versicolor (L. Koch, 1877). Artoriella flavimanus, the type species of Artoriella Roewer, 1960, is returned to Artoria. Of the remaining species of Artoriella, the Western Australian species A. cingulipes and A. taeniifera are transferred to Artoria, the African species Artoriella amoena Roewer, 1960, A. maculatipes Roewer, 1960 and A. lycosimorpha (Strand, 1909) are considered incertae sedis and Artoriella maura (Urquhart, 1891) from New Zealand is considered a nomen dubium. Trabaeola Roewer is a junior synonym of Artoria, as its type species, T. lineata, is transferred to Artoria. Trabea australiensis (L. Koch, 1877) is considered a nomen dubium. The genus Artoria is characterised by a unique apophysis near the base of the embolus of the male pedipalp. It does not fit into the existing lycosid subfamilies, which have been established by investigation of mainly Northern Hemisphere taxa. Artoria is widespread in Australia and species can be found in a range of habitats (swamps and riverbanks, open areas, rain and dry sclerophyll forests).

Abstract:

Invertebrates dominate the animal world in terms of abundance, diversity and biomass, and play critical roles in maintaining ecosystem function. Despite their obvious importance, disproportionate research attention remains focused on vertebrates, with knowledge and understanding of invertebrate ecology still lacking. Due to their inherent advantages, usage of camera traps in ecology has risen dramatically over the last three decades, especially for research on mammals. However, few studies have used cameras to reliably detect fauna such as invertebrates or used cameras to examine specific aspects of invertebrate ecology. Previous research investigating the interaction between wolf spiders (Lycosidae: Lycosa spp.) and the lesser hairy-footed dunnart (Sminthopsis youngsoni) found that camera traps provide a viable method for examining temporal activity patterns and interactions between these species. Here, we re-examine lycosid activity to determine whether these patterns vary with different environmental conditions, specifically between burned and unburned habitats and the crests and bases of sand dunes, and whether cameras are able to detect other invertebrate fauna. Twenty-four cameras were deployed over a 3-month period in an arid region in central Australia, capturing 2,356 confirmed images of seven invertebrate taxa, including 155 time-lapse images of lycosids. Overall, there was no clear difference in temporal activity with respect to dune position or fire history, but twice as many lycosids were detected in unburned compared to burned areas. Despite some limitations, camera traps appear to have considerable utility as a tool for determining the diel activity patterns and habitat use of larger arthropods such as wolf spiders, and we recommend greater uptake in their usage in future.

Full text

Abstract:

Due to the change of illumination environment and overlapping conditions caused by the neighboring fruits and other background objects, the simple application of the traditional machine vision method limits the detection accuracy of lychee fruits in natural orchard environments. Therefore, this research presented a detection method based on monocular machine vision to detect lychee fruits growing in overlapped conditions. Specifically, a combination of contrast limited adaptive histogram equalization (CLAHE), red/blue chromatic mapping, Otsu thresholding and morphology operations were adopted to segment the foreground regions of the lychees. A stepwise method was proposed for extracting individual lychee fruit from the lychee foreground region. The first step in this process was based on the relative position relation of the Hough circle and an equivalent area circle (equal to the area of the potential lychee foreground region) and was designed to distinguish lychee fruits growing in isolated or overlapped states. Then, a process based on the three-point definite circle theorem was performed to extract individual lychee fruits from the foreground regions of overlapped lychee fruit clusters. Finally, to enhance the robustness of the detection method, a local binary pattern support vector machine (LBP-SVM) was adopted to filter out the false positive detections generated by background chaff interferences. The performance of the presented method was evaluated using 485 images captured in a natural lychee orchard in Conghua (Area), Guangzhou. The detection results showed that the recall rate was 86.66%, the precision rate was greater than 87% and the F1-score was 87.07%.

Abstract:

The purpose of this study focuses on presenting the food and drink process in the case of making lychee juice and lychee-tea combination fruit juice in a tropical country such as Vietnam. We mainly use methods of qualitative analysis, synthesis and inductive methods, with description and explanatory methods. Authors also use a value chain approach from a material supply (lychee products) to production and market distribution.Research results show us that choosing good red lychee together with good green or black tea, esp. Lipton tea, which is produced from the region of material supplying in the Northern region of Vietnam, then mixed with sugar and ice, using little vegetables will be very good for everybody health, functioning as medical treatment to prevent heart disease, and helps men and women stronger.In the meantime, we also propose lychee and tea planting policies and capital financing policies in the country, esp. In the north of Vietnam. For instance, the nation needs to continue to negotiate with countries that have not yet allowed Vietnam’s fresh lychee to be imported into developed countries (such as Korea, ...); The state/province cooperates with donors and businesses in trade promotion activities in potential export markets for Vietnamese lychee and fruit products (Japan, Korea, US, EU, ASEAN…).

Abstract:

ABSTRACT Spider venom is a complex mixture of bioactive components, in which peptides play an important role by showing neurotoxicity or cytotoxicity. Disulfide-rich peptides are major components in the venom, but linear peptides without disulfide bridges are also present and often show antimicrobial activity. In this study, we analyzed the venom of the spider Lycosa poonaensis (Lycosidae) to find novel antimicrobial peptides using mass spectrometry. The result revealed that 120 out of 401 detected components were nondisulfide-bridged peptides. From them, the sequence of 2 peptides (lyp2370 and lyp1987) were determined by MS/MS analysis. The biological activity test revealed that lyp2370 has only weak antibacterial activity. On the other hand, lyp1987, which is identical to M-lycotoxin-Ls3b from the Lycosa singoriensi venom, showed significant antibacterial activity. The weak activity of lyp2370 was found to be due to the presence of a Glu residue on the hydrophilic face of its amphipathic α-helical structure.

Abstract:

The lychee is, all over the world, considered as the "queen of the fruits" due to the delicacy of its appearance and flavor. Although it was only recently that it started to have economical importance in Brazil, the lychee is already calling the attention of numerous farmers, mainly those who cultivate citric fruits and/or sugarcane in the State of São Paulo, due to the constant and at the same time growing necessity of finding new alternative crops. Considering that the commercial cultivation of lychee plants in the field requires the previous obtainment of rootstocks viewing to reduce the genetic variability and the length of the juvenile period displayed by plants resulting directly from the seeds, finding ways to improve the germination performance of lychee seeds for the production of rootstock plants is of considerable economic importance. Thus, the objective of this experiment was to test five substrates for the germination of lychee seeds: (1) vermiculite, (2) washed sand, (3) filter paper, (4) carbonized rice hull, and (5) sphagnum. The results showed that the period of time required by a lychee seed to germinate is a short one thus reinforcing the importance of providing a suitable substrate for the germination to take place. It was found that the substrates which apparently allowed the best combinations of water and oxygen availability for the seeds - washed sand and carbonized rice hull - were those leading to the fastest and highest germination values.

Abstract:

Lychee is a popular fruit in China and southeastern Asia. Although it is very popular, the microbiota of lactic acid bacteria (LAB) associated with lychee remains poorly described. Lychee samples from seven different markets located in three cities in Taiwan were collected and a total of 104 LAB were isolated. Through RFLP analyses of 16S rDNA and rpoA genes for grouping and 16S rRNA gene sequencing, these isolates were finally divided into 6 groups (A to F). The most common genera of LAB in lychee samples were Weissella and Leuconostoc. Weissella confusa strain E was found to produce a bacteriocin active against Listeria monocytogenes and some other Gram-positive bacteria. Mass spectrometry analysis revealed the bacteriocin mass to be approximately 3426.77 Da, which is different to other known Weissella bacteriocins. In addition, strain MB7 included in the genus Leuconostoc was identified as potential novel species or subspecies on the basis of phylogenetic analysis of 16S rRNA, rpoA and pheS gene sequences. Thus, this is the first report describing the distribution and varieties of LAB associated with lychee fruits. In addition, one potential novel LAB species or subspecies and one potential novel bacteriocin were also reported in this study.

Abstract:

Four experimental groups were used: (A) males Lycosa thorelli × female L. thorelli; (B) male Lycosa carbonelli × female L. carbonelli; (C) Male L. thorelli × female L. carbonelli; (D) male L. carbonelli × female L. thorelli. Males were placed in a field with conspecific sexual pheromone and confronted to anesthetized virgin females. Male L. thorelli showed a greater tenacity than male L. carbonelli in the maintenance of the copulatory position. The typical copulation pattern (intraspecific groups) became atypical in interspecific groups. Only one typical interspecific copulation was observed in group C. Male L. carbonelli showed a good specific discrimination when mounting the female, while male L. thorelli showed a low discrimination level. The maintenance of the copulatory position could be determined by a modal number of ejaculations in the case of male L. carbonelli and by a modal duration in the case of male L. thorelli. Atypical copulations might indicate a mechanical incompatibility between the genitalia of the two species. Typical copulations produced offspring, indicating the absence of postcopulatory isolation mechanisms.

Abstract:

Spider toxins are molecularly diverse and some display not only a strong antibacterial effect but also exhibit significant inhibition of tumor growth and promote tumor cell apoptosis. The aim of the present investigation was to explore different antitumor effects of the spider peptide toxin lycosin-I through different pathways at different concentrations. It was found that by inactivating STAT3 pathway, high concentrations of lycosin-I induce apoptosis in prostate cancer cells and low concentrations of lycosin-I inhibit the migration of prostate cancer cells. This finding provides favorable evidence for further study of the molecular diversity of spider toxins. Impact statement The spider peptide toxin has become an important research topic. These toxins are molecularly diverse and some display not only a strong antibacterial effect but also exhibit significant inhibition of tumor growth and promote tumor cell apoptosis. Inspired by previous studies, the present study aims to investigate the effects of different concentrations of lycosin-I on the invasiveness and apoptosis of human prostate cancer cells. The findings provide favorable evidence for further study of the molecular diversity of spider toxins.

Abstract:

Rice (Oryza sativa L.) is an annual crop that plays an important role in meeting the food sources of the Indonesian population. In addition, rice plants have a diversity of insects as their natural enemy. This study aims to determine the population of natural enemies of 3 rice varieties, namely Inpari 30, Ciliwung, and Mekongga varieties. The research location is the rice fields in Turikale Subdistrict, Maros District. The method used for the study was the survey location of rice fields with each paddy field size of about 20 x 15 m. The results showed that there were 3 types of predators namely Lycosa, Coccinella, and Orthetrum which were found in each variety with varied total numbers at every 2-week observation interval. The highest population of Lycosa was found in the Inpari 30 (6 wap) variety, the highest Coccinella population also was found in the Inpari 30 (10 wap) variety, while the highest Orthetrum population was found in the Mekongga variety (6 wap). The highest proportion of each variety was Lycosidae 50% in the Inpari 30 variety, Lycosidae 51.35% in the Ciliwung variety, and Lycosidae 44.44% in the Mekongga variety

Abstract:

Leaf isozyme banding patterns were studied in 30 cultivars and selections of lychee (Litchi Chinensis Sonn.) by means of starch gel electrophoresis. Polymorphism in aconitase, aspartate aminotransferase, isocitrate dehydrogenase, phosphoglucomutase, shikimate dehydrogenase, superoxide dismutase and triosephosphate isomerase is demonstrated for the first time and observations are extended for the previously described polymorphism in phosphoglucose isomerase. In this study we found five groups of cultivars with identical electrophoretic genotypes. The 18 different cultivars were clustered by the UPGMA method into two large clusters and three pairs of similar cultivars. Three cultivars were relatively separate from the clusters. This study shows that isozyme polymorphism is a prevalent phenomenon in lychee, and that isozymes can provide useful genetic markers for lychee cultivar identification and parental analysis.

Abstract:

Despite the increasing popularity in American markets of the fruit of the illustrious lychee (Litchi chinensis Sonn.), unreliable flowering and yield has had serious impacts on lychee growers in southern Florida. Lychee flowering is normally induced by chilling temperatures. Unpredictable weather, high rainfall, and excessive nutrients cause unreliable flowering in southern Florida. Although growers have no control over the weather, they need to be able to manage the growth, vigor, and reproduction of trees through practices that optimize flowering. When excessively watered and fertilized, lychee trees grow vigorously with frequent vegetative flushes every 2 to 3 months. The lack of maturity of these late vegetative flushes prevents flower stimulation from mild temperatures in January and February, when flowering typically occurs on trees that have not experienced vegetative flushes in the late fall or early winter. Thus, by adopting nitrogen fertilizer management practice, growers should be able to induce abundant flowering even in mild winters. Our preliminary results demonstrated that timing and rates of applications of nitrogen fertilizer significantly affected concentrations of soil and leaf N. High nitrogen levels in the leaves induced more vegetative flushes and less flowering, and consequently less fruit yield.

Full text

Abstract:

Spider venoms represent an original source of novel compounds with therapeutic and agrochemical potential. Whereas most of the research efforts have focused on large mygalomorph spiders, araneomorph spiders are equally promising but require more sensitive and sophisticated approaches given their limited size and reduced venom yield. Belonging to the latter group, the genus Lycosa (“wolf spiders”) contains many species widely distributed throughout the world. These spiders are ambush predators that do not build webs but instead rely strongly on their venom for prey capture. Lycosa tarantula is one of the largest species of wolf spider, but its venom composition is unknown. Using a combination of RNA sequencing of the venom glands and venom proteomics, we provide the first overview of the peptides and proteins produced by this iconic Mediterranean spider. Beside the typical small disulfide rich neurotoxins, several families of proteins were also identified, including cysteine-rich secretory proteins (CRISP) and Hyaluronidases. Proteomic analysis of the electrically stimulated venom validated 30 of these transcriptomic sequences, including nine putative neurotoxins and eight venom proteins. Interestingly, LC-MS venom profiles of manual versus electric stimulation, as well as female versus male, showed some marked differences in mass distribution. Finally, we also present some preliminary data on the biological activity of L. tarantula crude venom.

Abstract:

The lychee tree is native to China and produce small fleshy fruit up to 5&amp;thinsp;cm in diameter. Lychee production in Australia is worth >&amp;thinsp;$20&amp;thinsp;million annually. Pruning of trees encourages new growth, has a positive effect on fruiting of lychee, makes fruit-picking easier, and may increase yield, as it increases light interception and tree crown surface area. The objective of this research was to assess changes in tree structure, i.e. tree crown circumference, width, height and Plant Projective Cover (PPC) using multi-spectral Remotely Piloted Aircraft System (RPAS) imagery collected before and after pruning of a lychee plantation. A secondary objective was to assess any variations in the results as a function of various flying heights (30, 50 and 70&amp;thinsp;m). Pre- and post-pruning results showed significant differences in all measured tree structural parameters, including an average decrease in: tree crown circumference of 1.94&amp;thinsp;m; tree crown width of 0.57&amp;thinsp;m; tree crown height of 0.62&amp;thinsp;m; and PPC of 14.8&amp;thinsp;%. The different flying heights produced similar measurements of tree crown width and PPC, whereas tree crown circumference and height measurements decreased with increasing flying height. These results show that multi-spectral RPAS imagery can provide a suitable means of assessing pruning efforts undertaken by contractors based on changes in tree structure of lychee plantations and that it is important to collect imagery in a consistent manner, as varying flying heights may cause changes to tree structural measurements.

Abstract:

Lychee productivity (Litchi chinensis) has been decreasing since the appearance of the erinose mite Aceria litchii (Keifer) in the main producing regions. This mite causes erinose formation in leaflets, branches, and fruits, which affects fruit productivity and quality. This study referred to an assessment of the population dynamics of this mite associated with abiotic factors in different lychee varieties during 25 months. For the assessments, the germplasm bank of the Faculty of Agrarian and Veterinary Sciences, UNESP–Jaboticabal, state of São Paulo, with lychees in full production was used. The assessed varieties were Bengal, Americana, Brewster, Groff, and WB4. Aceria litchii occurred in lychee plants over the years, reaching the highest levels in October and November. These results are considered important for the establishment of a more adequate management program for A. litchii. In this study, we verified that the Bengal variety (widely commercialized) is one of the varieties more susceptible to the mite attack. The variety Americana showed resistance to the mite. Despite the occurrence records for the pest in this variety, the number of individuals and, consequently, the erinose was reduced. Information reported here on the relationships between lychee varieties and the main crop pest is essential to implement plant-breeding programs or even select resistant or tolerant varieties to the erinose mite.

Abstract:

Bio-based composites are reinforced polymeric materials, which include one or two bio-based components. Biocomposites have recently attracted great attention for applications ranging from home appliances to the automotive industry. The outstanding advantages are low cost, biodegradability, lightness, availability, and solving environmental problems. In recent days, biodegradable natural fibers are attracting a great deal of interest from researchers to work on and develop a new type of composite material for diverse applications. The objective of this work is to evaluate fire resistance and mechanical properties of epoxy polymer composites reinforced with lychee peel (Vietnam), at 10 wt%, 20 wt%, and 30 wt% mass%. The study showed that the mechanical properties and flame retardancy tended to increase in the presence of lychee peel reinforcement. In the combined ratios, 20 wt% lychee rind gave a limiting oxygen index of 21.5%, with a burning rate of 23.45 mm/min. In terms of mechanical strength, in which the Izod impact strength increased by 26.46%, the compressive strength increased by 25.20% and the tensile strength increased by 20.62%. The microscopic images (SEM images) show that the particle distribution is quite good and the adhesion and wetting compatibility on the two-phase interface of lychee peel-epoxy resin are strong.

Abstract:

Hot-water immersion and irradiation quarantine treatments are used to disinfest lychee (Litchi chinensis Sonn.) of fruit flies and other pests before export from Hawaii to the U.S. mainland. In the first experiment, one day after harvest, `Kaimana' lychee fruit were subjected to 1) hot-water immersion at 49.0 °C for 20 minutes, 2) irradiation treatment at a minimum absorbed dose of 400 Gy, or 3) left untreated as controls. Fruit were then stored at 2 or 5 °C in perforated plastic bags, and quality attributes were evaluated after 8 days. Lychee fruit treated with hot-water immersion were darker (lower lightness) and less intensely colored (lower chroma) than irradiated or untreated fruits at both storage temperatures. Fruit stored at 2 °C were darker (lower lightness) than fruit stored at 5 °C, but fruit held at 5 °C had greater weight loss. External appearance of fruit treated with hot-water immersion was rated as unacceptable, whereas irradiated and nontreated fruit were rated as acceptable. Taste of fruit was rated as acceptable in all treatments. In the second experiment, lychee fruit were subjected to 1) hot-water immersion at 48, 48.5, or 49 °C for 20 minutes or 2) irradiation at 400 Gy, or 3) left untreated as controls. Fruit were then stored at 4 °C in perforated plastic bags, and external appearance of the pericarp was evaluated after 1, 2, 5, 7, 8, and 9 days. Pericarp darkening was more rapid for lychee fruit treated with hot-water immersion than irradiated or control fruit, and the degree of quality loss increased with increasing hot-water immersion temperature. Overall, under these experimental conditions, irradiation was superior to hot-water immersion as a quarantine treatment on the basis of fruit quality maintenance.

Abstract:

Experiments were conducted at the net house and laboratory of the Entomology Division of Bangladesh Institute of Nuclear Agriculture (BINA) to determine the effectiveness of four light sources for light trapping, and performance of three predators for controlling brown plant hopper, Nilaparvata lugens (Stal.).The light intensity and sources were 30-50 lux (candle light), 80-100 lux (kerosene lamp), 180-200 lux (bulb) and 380-400 lux (energy saving lamp). The predators, ladybird beetle, carabid beetle and wolf spider, Light traps of 380-400 lux from energy saving lamp showed maximum effect in reducing the pest brown planthopper. Other light sources had little effect on brown planthopper. Light source of 30-200 lux reduced only a few brown planthopper. The predator wolf spider, Lycosa pseudoannulata consumed all the prey individuals of Nilaparvata lugens in three days exposure period indicating its high predation potentiality. Performance of ladybird beetle, Micraspis discolor was moderate and the carabid beetle, Ophionea indica was poor in controlling brown planthopper. The findings of these experiments indicate that light trapping with a source of 380-400 lux, predation by Lycosa pseudoannulata are the promising options in reducing brown planthopper population successfully and it could be an important part of IPM that is essential for the sustainable management of this deleterious brown planthopper in rice cultivation. Progressive Agriculture 30 (3): 275-281, 2019

ABSTRACT: Lychee is one of the most popular exotic fruits in Brazil, and has both in natura and industrial potential. The objective of the present study was to evaluate the influence of the number of leaflets on lychee herbaceous cuttings treated with the indolebutyric acid (1000mg L-1). The experimental design was completely randomized, with 4 replications and 10 cuttings per experimental plot. Treatments consisted of cuttings with zero (0), one (1), two (2), three (3), and four (4) leaflets. After 180 days, the rooting and survival percentages and the number and length of roots were evaluated. The data were subjected to polynomial regression analysis. The increase in the number of leaflets was advantageus for all studied variables, with an increase in the survival, rooting of cuttings, and number and length of roots. The herbaceous cuttings of lychee tree are viable, provided that at least four leaflets remain in the herbaceous cutting.
