Full textAbstract:
Orthoptera comprise an order of common insects, most of which are phytophagous, but there are also predatory orthoptera. They are found all over the world and adapt to the environmental conditions in which they are found. Orthoptera insects are pests of vegetable plants, destroying large areas, so vegetable growers are familiar with them. The research was carried out in the Amărăștii de Jos stationary in 2020 in vegetable crops. The aim of the research was to identify orthoptera species in vegetable crops and two methods were used to collect them: the beer trap method and the Barber soil trap method). Orthopteran insects were identified with the help of specialized determiners, then classified by family down to species level. Orthoptera currently identified in the stationary studied included six species, namely: Gryllotalpa gryllotalpa, Gryllus campestris, Gryllus desertus, Acrida hungarica, Dociostaurus maroccanus and Calliptamus italicus. The species with the most specimens is Gryllotalpa gryllotalpa (42 specimens) and the species with the fewest specimens is Dociostaurus maroccanus (3 specimens).

Full textAbstract:
Among insects orders, Blattodea and Orthoptera are characteristic with their high significance to human habitation, as posing medical and agricultural problems. Representatives of Blattodea have an important role as carriers of a number of infectious diseases in humans and animals, and are directly related to human life and activities. On the other hand Orthoptera are very significant as agricultural pests that cause great damage to plants. The study of the mechanisms of immune defense and the processes related to the response against pathogenic infections in these two orders is of interest in order to more fully clarify the possibilities for management and control of their populations. This review summarizes the information on the defense mechanisms (hemocytes, antimicrobial peptides, pathogen recognition, signaling patways, immune and antiviral responses) studied in representatives of these two orders. The list includes 30 species of cockroaches and termites and 59 orthopteran species, and focuses on species with medical significance (Periplaneta americana, Blattella germanica) and insect pests for agriculture such as Locusta migratoria and Schistocerca gregaria.

The effectiveness of controlling polysis aphids and greenhouse orthoptera using a suspension of P.varioti's strain EMR-57 and insecticide Fufanon was evaluated in a tomato-planted greenhouse. The study found that the mortality rate of polysis aphids reached 57.8% within 3 days and 67.6% within 14 days when the P.varioti's strain EMR-57 suspension with a titer of 6·107 cfu/ml was applied. In the case of greenhouse orthoptera, the mortality rate was 60.0% and 78.8% within the same respective time frames. Contrastingly, in the water-sprinkled version, the mortality rate was significantly lower, with only 2.6% mortality within 3 days and 4.3% and 3.3% in 1 and 7 days, respectively. This indicates that the P.varioti's strain EMR-57 suspension is more effective when directly applied to the target pests compared to a general water-sprinkled application. In greenhouse conditions, the most optimal rates for controlling both pests were found to be the combination of 2.5 L/ha of Fufanon insecticide, 6·107 cfu/ml titer of P.varioti strain EMR-57, and 0.04% concentration of "Selver" adhesive active substance. This combination showed effective control of both polysis aphids and greenhouse orthoptera, highlighting its potential for integrated pest management strategies in greenhouse agriculture.

Full textAbstract:
This current review describes the morphology of some polyphagous species of insect pests affecting medicinal plants, their life cycle, host plants, form of damage and biological management. The described insect species are part of the following orders: Orthoptera, Hemiptera, Coleoptera, Lepidoptera and Dipera. All species are distributed in Europe, but can also be found in other continents. Defoliation is the most common type of damage caused by adults and larvae (or nymphs) but additional types of damage have also been reported. In order to control them, biological measures have to be taken, chemical control being unsuitable for medicinal plants. This bio-management can be achieved through pathogens of the insect pests, such as fungi and parasitoids.

Sweep-nets and pitfall traps were used to examine the distribution and dynamics of predominant predators and pests in turfgrass foliage in parks, golf courses and suburban/rural landscapes in 1991 and 1992. Araneae, Formicidae, and Coccinellidae were the most abundant predators in the sweeps, while Araneae, Formicidae, and) Carabidae were the most abundant predators in the pitfall traps. In both years, Araneae comprised over 60% of the total predators in the sweep samples. Formicidae (>70%) and Araneae (13–19%) were the most abundant arthropod predators in the pitfall samples. Cicadellidae, Chrysomelidae, and Orthoptera accounted for over 96% of the prey in the sweep samples, while Cicadellidae, Orthoptera (grasshoppers and crickets), and Aphididae comprised over 90% of the prey in the pitfall samples. Abundance of predators and prey, and prey / predator ratios fluctuated with site, date, and distance from the trees. During the season, high prey / predator ratios usually preceded peak prey abundance in the sweep samples. Predators usually were more prevalent in sweep samples closer to tree borders, while prey populations tended to be higher at distances further from the tree borders. These results suggest that tree borders provide food, shelter, and refuge for predators during periods of environmental stress.

Most orthopteran insects are phytophagous and some are important pests in agriculture and forests. Many intestinal microflora of Orthoptera insects have been reported, primarily from Acridoidea and there have been few reports of other taxa. In this study, we collected 15 individuals representing five species (<i>Ruspolia lineosa</i>, <i>Tetrix japonica</i>, <i>Erianthus versicolor</i>, <i>Gryllotalpa orientalis</i> and <i>Teleogryllus emma</i>) belonging to five orthopteran superfamilies (Tettigonioidea, Tetrigoidea, Eumastacoidea, Gryllotalpoidea and Grylloidea) to characterise and compare the gut microbiota with greater taxonomic width by performing sequencing analysis of the 16S rRNA V4 region in gut material. A total of 606,053 high-quality sequences and 3,105 OTUs were acquired from 15 gut samples representing 24 phyla, 48 classes, 69 orders, 133 families and 219 genera. Firmicutes and bacteria were the most abundant phyla, followed by Bacteroidetes, Cyanobacteria, Actinobacteria and Acidobacteria. At the genus level, <i>Serratia</i>, <i>Citrobacter</i>, <i>Wolbachia</i>, <i>Lactobacillus</i> and <i>Parabacteroides</i> were the most predominant genera in <i>R. lineosa</i>, <i>T. japonica</i>, <i>E. versicolor</i>, <i>G. orientalis</i> and <i>T. emma</i>, respectively. Both Principal Coordinates Analysis (PCoA) and heatmap results revealed significant differences in bacterial community composition across species. Additionally, alpha diversity analysis indicated the bacterial richness was significantly different amongst the five species.

This survey was done in several guava fields around Bogor and found many unhealthy plants infested by various plant pests and diseases. This study aimed to analyze the effect of various guava cultivars on pest and disease intensity on guava in the Sub-District of Tanah Sareal, Bogor. Samples were collected from 20 fields that consisted of 15 samples of Getas Merah and 5 samples of Bangkok Putih cultivars to identify plant pests and diseases. Interviews were done with field owners to obtain information on cultivating practices. Pests found based on morphological identification included plant bugs (Hemiptera: Miridae), locusts (Orthoptera: Acrididae), bagworms (Lepidoptera: Psychidae), Geometrid caterpillars (Lepidoptera: Geometridae), Pyralid caterpillars (Lepidoptera: Pyralidae), scale insects (Hemiptera: Coccidae), planthoppers (Hemiptera: Flatidae), and mealybugs (Hemiptera: Pseudococcidae). Disease and pathogens identified included red rust disease (Cephaleuros sp.), anthracnose (Colletotrichum gloeosporioides), and fruit cancer (Pestalotia sp.). The occurrence of biting-chewing type pests was greater than piercing-sucking type insects, including 33.33% and 34.99%. Red rust disease was the dominant disease found on both guava cultivars consisting of 68.88% and 63.33% of the samples.

Full textAbstract:
Sweet corn (Zea mays saccharate) is cultivated in Denpasar, Bali, which is harvested when it is young for daily use, both for vegetables and for consumption, boiled or grilled. Most of the pests found were borers (Ostrinia furnacalis, Crambidae, Lepidoptera), flies (Musa domistica, Muscidae, Diptera), grasshoppers (Locusta sp., Acrididae, Orthoptera) and rats (Rattus rattus, Muridae, Rodentia). The pest diversity index ranged from 0.519-1.003, the pest dominance index ranged from 0.269-0.600 and the evenness index between species ranged from 0.094-0.700. This means that the diversity is very small, supported by a small evenness index, which also means that there are insect pests that dominate. Population dynamics of insect pests range from 0.10 to 0.21, which means the number of births and additions per day per hundred is 10 to 21 individuals. The relationship between pests and weather factors (temperature and humidity) only for borers (located on Jalan Sekarsari) has a significant positive correlation of 0.77* with the regression equation Y = 0.348 X – 24.356 (R2 = 0.71, X = temperature and Y = borer population).

Full textAbstract:
Background: Baringeng is a corn-producing village in Soppeng Regency, South Sulawesi. The main problem for corn farmers in the town is insect pests. Insect pests damage the plant, which has an impact on decreasing yields. Control of insect pests must be by the type of insect pests. This study aims to calculate the diversity of insect pests of corn in Baringeng Village and the damage they cause. Methods: Data was collected in Takku Hamlet, Baringeng Hamlet, and Tanjonge Hamlet. with a systematic plot sampling method with the help of light traps, sweep nets, and direct collection of pests. Observations included the number of individuals and types of insect pests. Data were analyzed by the Shannon-Wiener diversity index (H'), evenness index (E), dominance index (C), and similarity index. Results: There were three types of insect pests with a total of 153 individuals that attacked corn in Baringeng Village, namely grasshoppers (Oxya sp.), planthoppers (Peregrinus maidis), and armyworm (Spodoptera frugiperda). The diversity index is included in the low category (H'=0.89), the evenness index (E) is in the high sort (E=0.81), the dominance index is in the low sort (C=0.44), and the lowest similarity index shown between Dusun Baringeng and Dusun Takku (IS=50%). Conclusions: The types of insect pests found in Baringeng Village come from three different orders, namely Orthoptera, Lepidoptera, and Hemiptera. Each problem shows other attack characteristics, but all attack the leaves. So that pest control can use natural materials by spraying on leaves, polyculture, crop rotation, or taking pests directly.

Full textAbstract:
Locusts and grasshoppers (Orthoptera: Acridoidea) are among the most dangerous agricultural pests. Their control is critical to food security worldwide and often requires governmental or international involvement. Although locust and grasshopper outbreaks are now better controlled and often shorter in duration and reduced in extent, large outbreaks, often promoted by climate change, continue to occur in many parts of the world. While some locust and grasshopper control systems are still curative, the recognition of the damage these pests can cause and the socioeconomic consequences of locust and grasshopper outbreaks have led to an increasing paradigm shift from crop protection to preventive management. Effective preventive management strategy relies on an improved knowledge of the pest biology and ecology and more efficient monitoring and control techniques.

Full textAbstract:
An arthropod sampling survey was performed in two palm groves from the wilaya of Biskra and Ouled Djellal. During 12 months (2020) of survey, the obtained results indicated the presence of 117 taxons divided into 2 classes (Insecta =103 species and Arachnids = 11 species). The species belonged to the orders: Coleoptera, Diptera, Orthoptera, and Hymenoptera. The Coleoptera order was the most represented in the two palm groves (32 from Ouled Djellal (OD) and 6 from Feliache (Fe)). The major trophic guild represented in the oasis ecosystems was the predator guild (OD= 39%, Fe=32%) in comparison to those of phytophagous (OD= 28%, Fe=12%) and pests (OD= 4%, Fe=15%). This indicates an ecological balance in the investigated oasis ecosystems between pests and their predators. The observation of two new species: Scymnus frontalis (Fabricius, 1787) and Diomus zinon (González and Honour, 2011), from the Coccinilidae Family increases the number of predator species of insect pests in the investigated oasis ecosystems.

ABSTRACT
 
 The aim of this study was to determine and analyze the effectiveness of long bean refugia (Vigna unguiculata) and Telekan flower (Tagetes erecta) against the Important Value Index (INP) and diversity of natural enemies and pests in organic rice. This research was conducted from July to September 2021 in the organic rice fields of Sumberngepoh Village, Lawang District, Malang Regency.

A study on diverse insect pest complex of field pea was made in both the years of experimentation i.e. during Rabi, 2021-22 and 2022-23 at Crop Research Centre, College of Agriculture, SVPUA&T, Meerut. As many as 15 insect species were recorded during the study period which belongs to different orders viz. Orthoptera (one species), Hemiptera (four species), Lepidoptera (seven species), Isoptera (one species) and Diptera (two species). All the major parts of this legume plant viz., pod/seed, leaf, root and stem were found to be infested by the insect pests. Sucking insect pests appear during the seedling and vegetative stage of crop i.e. 1st week of December to 2nd week of January. Gram pod borer, pea pod borer and blue butterfly are the pod borer complex that appeared from flowering to maturity stage i.e. 1st week of January to 2nd week of February. Among all the fifteen insect pests, only two pod borers, Etiella zinckenella (Treitschke) and Helicoverpa armigera (Hübner) were found as major pests of field pea with severe economic status to this area during successive Rabi, seasons.

The aim of this review is to explore the potentials existing in insecticides that are considered Insect Growth Regulators (IGR) for the control of insects considered crop pests, with an observation of the main mechanisms of neuroendocrine modifications, development and viability of the species used as study models. The data search on digital platforms, as well as the screening of materials about crop pests, resulted in 74 IGR references and their potentials. The analysis of the information found demonstrated a greater use in works of compounds belonging to chitin synthesis inhibitors class; and orders such as Hemiptera, Lepidoptera, Coleoptera, Orthoptera, Thysanoptera and Diptera were represented in the studies. The main types of activities reunited were morphological and anatomical modifications, reproductive modifications, alterations in developmental stage, alterations in developmental period, ovicidal activity, larvicidal/ninficidal activity and fagoinhibition. The congregated knowledge about the main pests used as study models, the main IGRs compounds and their biological potentials allow an evaluation of their use as an informative source for crop pest control methods.

Abstract Because turfgrass is maintained in various settings, such as golf courses, lawns, and commercially grown in sod farms, it is critical to understand its major insect pests and management practices. A survey was conducted to determine the major insect pests and current management practices in the commercial turfgrass industries in Georgia. A total of 32 respondents representing golf courses and sod farms participated in the survey. A significantly greater number of respondents represented golf courses (75% of 32 respondents) than sod farms (25%). The respondents (n =31) identified fall armyworm, Spodoptera frugiperda J.E. Smith (32.5%), white grubs, Phyllophaga spp. (20.8%), mole crickets (Orthoptera: Gryllotalpidae; 16.9%), and others (22%) as major pests in comparison to billbugs, Sphenophorus spp. (7.8%) and chinch bugs, Blissus spp. (0%). Of 31 respondents, 64.5% applied insecticides two to five times and 22.5% respondents applied insecticides 5–10 times for insect management each year. Among nonchemical tools (n=24), most respondents opted to do nothing (70.8%) than use biological control (0%), host plant resistance (25%), or other management tools (4.2%).

Full textAbstract:
Indonesia is an agrarian country with agriculture as the highest livelihood for its population. The agricultural sector that is the main pillar in Indonesia's food supply is in terms of rice agriculture (Oryza sativa), especially as the global population continues to grow. However, a challenge that often lurks in efforts to increase rice production is the attack of insect pests. Insect pests result in significant crop losses and threaten food security. It is necessary to identify rice pest insects as an effort to extract information on the types of insects that harm agriculture. This study using qualitative descriptive methods aims to determine the types of insect pest species on agricultural land in Gunung Sarik Village as a consideration in proper pest control management, so as to improve the quality and quantity of rice crops in the agricultural land of Gunung Sarik Village. Based on the results of the observations, it was found that types of insect pests come from two different orders, namely hemiptera, which include leafhoppers, walang sangit, and black ants, and the order orthoptera or grasshoppers.

Out of 20 fecal samples collected, seven were of Eptesicus furinalis and 13 of Myotis nigricans. The diet of E. furinalis included six orders of insects: Coleoptera (5/7 by items presence), Lepidoptera and Hymenoptera (3/7), Diptera, Hemiptera and Homoptera (1/7). The diet of M. nigricans included all the main orders consumed by E. furinalis (6/13, 4/13, 4/13, 3/13, 1/13, and 4/13 respectively) and one other order: Orthoptera (1/13). Homoptera, Diptera and Orthoptera were collected only in bats captured in gallery forest. There is 80% of overlap in the diet of these two species. Predation on species of Scarabeidae, Hesperiidae, Sphingidae and Saturniidae families confirms bats potential as biological control agents of pests in agricultural ecosystems.

Abstract Cattle egret (Bubulcus ibis) is a widespread avian species inhabiting a variety of natural and artificial sites. Asam Kumbang Crocodile Park is one of establishments that occupied some portions of B. ibis habitat with no recent information on the food resource and prey availability for the viability of B. ibis. To this aim, we collected 10 random individuals of B. ibis to be sacrificed for gut content analysis of prey species. A total of 19 taxa was found as prey items in the gut of B. ibis with the dominant group from insects (Orthoptera, Scolopendromorpha). The diversity of prey species was categorized as moderate with intraspecific diet variation which formed four guilds that fed on specific taxa namely Group 1 (Haplotaxida, Lepidoptera, Anurans), Group 2 (Blattodea, Coleoptera, Araneae), Group 3 (Orthoptera, Scolopendromorpha); and Group 4 (Dermaptera, Squamata). Oxya chinensis and Oxya velox are important rice grasshopper pests that were also found in the gut of B. ibis reflecting their potential function as biological control agent.

AbstractDefinition of the genus Calliptamus (Orthoptera: Acrididae) has generated many taxonomic debates. Even now, the existence of different geographical morphs hinders species determination, particularly as concerns females and larvae. Some of these species are observed in southern France and are recognized as potential pests. To circumvent problems of species identification in ecological surveys, we developed a single multiplex PCR method based on mitochondrial Cytochrome Oxydase I diagnostic polymorphisms to differentiate between the four species, Calliptamus italicus, C. wattenwylianus, C. siciliae and C. barbarus, in southern regions of France.

The survey involved 150 randomly selected farmers who were interviewed using structured questionnaire. Fruit vegetables planted by the farmers were okra, tomatoes, pepper and garden egg. Reasons given by farmers for cultivating fruit vegetables were significantly favored by age category, educational qualification, and secondary occupation of farmers (x2 = 4.757, P = 0.029). Field insect pests were perceived as the major production constraint to fruit vegetables in this zone. Majority of the farmer estimated 78.4 % rated insect pest as the most serious pest infesting fruit vegetables, the insect pests were grasshopper (Orthoptera), beetles (Coleoptera) and caterpillar (Lepidoptera). Integrated pest management module consisted basically of chemical and cultural control strategies, with weeding, shifting cultivation and crop rotation as main cultural control methods. More than 76.7 % of the farmers make use of cultural control because of unavailability and cost of chemical insecticides. Only 23.3 % had access to chemical insecticides in controlling insect pest of fruit vegetables.

Full textAbstract:
Grasshoppers (Orthoptera: Acrididae) frequently inflict damage on millions of hectares of western rangelands and crops. The main method of controlling grasshopper outbreaks consists of covering their infestations with chemical insecticides. Although it is relatively cheap, fast, and efficient, chemical control bears serious risks to human health, non-target organisms, and the environment. To overcome this challenge, biological control is a less environmentally hazardous alternative to traditional, synthetic insecticides. This paper reviews strategies that could be used as effective ways to control such pests with a special focus on effective bait formulations that might provide a key model in developing biological control strategies for the grasshopper population.

Today, climate change, an increase in anthropogenic factors, and changes in the natural environment have an adverse effect on insect diversity due to the changing climes around the world. There has been an increase in the number of pests of agricultural crops over the past few years because of the expansion of the cultivated areas in arid regions, including the number of insects of the Order Orthoptera. The formation of fauna in different regions of the globe needs to be identified in order to improve the methods of combating them, and therefore, it is necessary to identify their formation. A great deal of research on the class of insects has been conducted over the last 35 years, and most of those articles are published in English. However, the research work on Insecta: Orthoptera was carried out in different topics and ways during those 35 years. The scope of this article is to cover all articles that have been published about orthoptera between 1986 and 2021 in the Scopus database. Various categories were analyzed in order to determine the quality of this research, including the year of research, who was responsible for the research, and which of the major research institutes did the research. In the light of the analysis, it is possible to have a certain understanding of the current research problems that are being experienced in this area as a result of the analysis.

Orthopteroidea is an ecologically diverse group of incompletely transformed insects that includes several insect orders similar in development and structure. Many species from Dermaptera, Orthoptera, Mantodea, and Blattodea are sensitive to anthropogenic influences and are indicators of the external environment. Some species cause damage to agriculture and forestry; others are inhabitants of human dwellings and pests of food supplies. The aim of this study is to describe fauna of some orders of Orthopteroidea in the Republic of Mordovia, in the central part of European Russia. This study was conducted in April–October 1971, 1984, 1995, 1996, 1998, 2000, 2001, and 2004–2023. All possible habitats were studied using a variety of methods (entomological traps, pitfall traps, pan traps, etc.). An acoustic method of species identification was also used. For each observation, the coordinates of location, abundance, and dates were recorded. The dataset contains 4865 occurrences. In total, 16,644 specimens of Orthopteroidea were studied. The dataset contains 71 species including Dermaptera (4), Orthoptera (62), Mantodea (1), and Blattodea (4). Of these, 13 species are identified for the first time in the region; these mainly inhabit steppe areas. The presence of two Orthoptera species has not been confirmed yet during our studies; these species are noted in this paper according an old published paper. The biodiversity of Mordovia includes 73 species from four orders. The biology of numerous species, their seasonal dynamics, and some descriptions of biotopes and number of new species are described.

Locusts and grasshoppers (Orthoptera: Acrididae) are pests of agricultural importance, devastating crops and pastures. This group includes hundreds of pest species and affects the livelihoods of one in every ten people worldwide. Their outbreaks can be chronic or episodic, with alternating periods of invasion and recession. Here, we review the natural enemies of locusts and grasshoppers in both their native and invaded ranges across the globe to assess the need for their conservation and maintenance as part of the natural suppression of outbreaks and to augment outbreak suppression as potential biological control agents. More than 70 natural enemies have been reported to attack locusts and grasshoppers, including entomopathogenic fungi, bacteria, nematodes, predatory insects, birds, reptiles, and mammals. Particular attention is given to the well-studied species of locusts and grasshoppers for which more information is available and to natural enemies in the locust-affected countries as part of the recent trend of looking for indigenous natural enemies. Such organisms can play a vital role in integrated pest management strategies for locusts and grasshoppers, particularly entomopathogens that can be incorporated with chemical pesticides into the management system. Among the organisms considered, <i>Metarhizium acridum</i> is noteworthy for inclusion in integrated pest management programs.

AbstractAdult grasshopper (Orthoptera: Acridoidea, Tetrigioidea Tettigonioidea) assemblages were sampled at four localities in south-eastern Shoa, around Debre Zeit, Ethiopia, between August 1986 and September 1988. Three localities were followed for the whole period but the fourth locality was followed only between August 1986 and July 1987. Samples were taken fortnightly from both black and light soil fields of tef and wheat crops, each in three replicates. The fauna consisted of twenty-nine taxa of both short- and longhorned grasshoppers, twenty-six of which are identified to species. Over 70% of the species belong to Acrididae and most of them are either pests or potential pests of cereal crops. Species richness, diversity and dominance within and between sites and seasons did not differ much during the two year period. The composition and structure of the assemblage was relatively constant. Despite fluctuation in abundance, dominant and common species remained common and rare species rare. Aiolopus longicornis Sjöstedt was most dominant. Some species are more abundant on black soil than on light soil and vice versa. The results are compared to grasshopper assemblages studied elsewhere.

Soya – is the main albuminous and oily crop of the world agriculture. It takes an important place in the structure of crops, grain, fodder and food balance. This is a strategic crop in solving the global food problem that is why it is grown on all continents in the main agricultural regions of our planet. In recent years soya has no competitors by the rates of crops growth and production volumes. Though Ukraine takes the first place in Europe by area of soya cultivation, its yield still does not correspond to potential possibilities. One of the factors which limit potential productivity is pests. Soybean protection from them is an important and relevant component for getting stably high yields and raising the quality of seeds simultaneously. Especially effective it has been monitoring in recent years as a result of an increase of sown areas and yield due to implementation of intensive technologies for soya cultivation. However, it should be taken into account that many species of harmful insects damage soya at all stages of ontogenesis, at the same time the loss of yield can make 30–40%. Harmful insect species from the following series have been discovered on soya crops in the Eastern Forest-Steppe of Ukraine: Orthoptera, Homoptera, Hemiptera, Thysanoptera, Coleoptera and Lepidoptera.

Shorea robusta Gaertn. f. (Dipterocarpaceae), commonly known as sal, is one of the most important timbers of India both ecologically and economically. It is of Indian origin, widely distributed in central and north India and constitutes an important ecosystem, which provides cool and calm environment rich in biodiversity. This tree species has a highest number of insect fauna among the forest trees. Of about 346 insects recorded on sal, about 155 species of insects belonging to the order Lepidoptera (105), Coleoptera (31), Thysanoptera (9), Hemiptera (4), Orthoptera (4), Ephemeroptera (1) and Isoptera (1) are associated with living tree. The major insect pests of sal are, ‘seed and seedling borer’ Pammene theristis Meyrick (Lepidoptera: Eucosmidae), feeding on seed while they are on the tree; Sitophilus rugicollis Casey (Coleoptera : Curculionidae), damage seed either on the forest floor or during storage; white grubs such as Holotrichia spp. (Coleoptera : Scarabaeidae), which feed on the root system of the plants in nurseries and beetles feed on the foliage; defoliators such as Caviria sericea Moore (Lepidoptera : Lymantriidae), Lymantria mathura Moore (Lepidoptera : Lymantriidae), Paectes subapicalis Walker (Lepidoptera : Noctuidae), Trabala vishnou Lefebvre (Lepidoptera : Lasiocampidae), which feed on the leaves; stem borer such as Hoplocerambyx spinicornis Newman (Coleoptera : Cerambycidae) and sap sucker, such as Drosicha stebbingi Green (Hemiptera : Coccidae). Termites, such as Coptotermes curvignathus Holmgren (Isoptera : Rhinotermitidae) and timber borers, such as Sinoxylon anale and S. crassum (Coleoptera : Bostrychidae), damage sal timber in dying, felled or stored logs in depots.

Abstract This work provides the results of a survey of entomonematodes parasites of grasshoppers in grasslands of the Pampean Region, Argentina. Nymphs of Staurorhectus longicornis Giglio-Tos, Laplatacris dispar Rhen, 1939, Dichroplus elongatus Giglio-Tos, 1894 and Metaleptea brevicornis (L.) (Orthoptera: Acrididae) were collected. Mermithidae was the only family registered with seven species: Agamermis decaudata Cobb, Steiner and Christie, 1923, Amphimermis bonaerensis Miralles and Camino, 1983, Amphimermis dichroplusi Camino and Lange, 1997, Amphimermis ronderosi Camino and Lange, 1997, Hexamermis coclhearius Stock and Camino, 1992, Hexamermis ovistriata Stock and Camino, 1992, and Longimermis acridophila Camino and Stock, 1989. The values of parasitism ranged between 1-12%, and intensity not overcome the number of 5.0 nematodes per larva. The nematodes observed showed specificity, not registering the same species of parasite in more than one host species. The Pampean region constituted an area with high diversity of mermithids where new species could be consider as bioregulator agents of this troublesome insect pests in agricultural areas of Argentina.

Full textAbstract:
The article deals with clarifying the species composition of black currant (Ribes nigrum l.) pests in the Right-Bank Forest- Steppe of Ukraine. During 2005-2020, 29 species of phytophagous insects from 15 families of 7 series and 2 species of phytophagous mites (Cecidophyopsis ribis Westw., Tetranychus urticae Koch.) were found in black currant plantations. The largest part (29% of the total number of detected species) in the structure of insect pests was occupied by representatives of a number of beetles (Coleoptera, among which the most common and harmful is the agrilus (Agrilus viridis L. ab aubei C-C.). Pests of the lepidopterans (Lepidoptera) were represented by 7 species from 5 families and accounted for 24% of the structure of the harmful entomocomplex. The most harmful representatives of this series are the currant clearwing moth (Aegeria tipuliformis Cl. (Synanthedon tipuliformis Cl.)) and common currant tortrix (Pandemis ribeana Hb.). The part of the series of homopterans (Homoptera) in the structure of the phytophagous complex was 17%, which were represented by five species of pests of the family Aphididae (aphids), among which the aphid currant (Aphis schneideri Born) is dominant. Phytophagous insects from the series hemipterans (Hemiptera), hymenopterans (Hymenoptera), dipterans (Diptera) and orthopteroids (Orthoptera) were represented by only 1–4 species and had no economic significance in terms of population density and harmfulness. Two species of herbivorous mites were also identified: the currant bud (Cecidophyopsis ribis Westw.) and the common spider mite (Tetranychus urticae Koch.). In terms of trophic specialization, polyphagous insects dominated, and phytophiles (dendrobiots) dominated in life forms.

Full textAbstract:
A field study was conducted during the 2020 and 2021 rice-growing seasons across three lowland rice cultivation sites—Singrijan, Medziphema, and Kuhoxu in Nagaland—to assess the diversity and abundance of insect pests and their natural enemies. A total of 32 insect pest species were documented representing 28 genera, 16 families, and five insect orders (Hemiptera, Lepidoptera, Orthoptera, Coleoptera, and Thysanoptera). Additionally, 57 species of natural enemies were recorded, spanning 42 genera, 19 families, and 10 insect orders, along with 6 species from the class Arachnida (Araneae). Eight insect specimens remained unidentified. Diversity analysis revealed site-specific variations, with Medziphema exhibiting the highest insect pest diversity, while Singrijan showed the highest diversity of natural enemies. Despite these differences, overall alpha, beta, and gamma diversity metrics indicated low species turnover among the study sites, suggesting high similarity and a stable ecological balance within the rice agroecosystem.
