This study aimed to document the diversity, distribution, and feeding habits of insect pests associated with the crop. a total of 17 insect species from seven orders (coleoptera, hemiptera, diptera, hymenoptera, lepidoptera, orthoptera, and thysanoptera) were recorded, with coleoptera (41.18%) and hemiptera (29.41%) being the most dominant. the family chrysomelidae had the highest representation with four species, while other families had one species each. The pests were categorized by feeding behavior: defoliators (11 species, 64.71%), sap-suckers (5 species, 29.41%), and tissue feeders (1 species, 5.88%). chewing insects, especially coleopteran defoliators, were the main cause of crop damage, while sap-sucking pests caused indirect damage through nutrient depletion and pathogen transmission. These findings provide a baseline for understanding pest dynamics, which is essential for developing effective integrated pest management (ipm) strategies to reduce crop losses while highlighting the need for regular monitoring and management of both defoliators and sap-sucking pests.

Thrips, insects of the order Thysanoptera, play key roles as crop pests, pollinators across diverse plant families, predators of other arthropods, and contributors to forest ecosystem dynamics. Despite the high diversity of thrips in tropical regions, these areas remain insufficiently studied. A survey of thrips was conducted during the Tama Abu Scientific. A total of 46 species belonging to three families were collected. The majority (50%, or 23 species) of the collected species belonged to the family Thripidae. Aoratothrips tenuis Priesner (subfamily Panchaetothripinae) and Elaphrothrips sensitivus Priesner (subfamily Idolothripinae) had not been previously recorded from Malaysia. An annotated list of Thysanoptera collected is provided. This list is by no means exhaustive, as it is based on a limited collecting period; many further species can certainly be expected from the Tama Abu Range and its adjacent areas.

ABSTRACTSince insect pollinators are essential for their ecological and agricultural roles, their conservation should be a priority, particularly in the remnant green spaces within highly urbanised cities. To gain insight into the occurrence of interactions between plants and often overlooked pollinators, and into their requirements for persistence over time in urban green spaces, we studied flower visitor diversity associated with a remnant of native vegetation in Cordoba (Argentina), one of the largest cities in South America. We recorded 198 insect species from six orders (Hymenoptera, Diptera, Lepidoptera, Coleoptera, Thysanoptera and Hemiptera) interacting with the flowers of 94 plant species. The plant–pollinator interaction network was significantly modular, with 178 pollinators playing a peripheral role (i.e., it has a few links inside its own module and rarely any to other modules). We focused on the life history traits of these peripheral pollinators, which are often neglected in ecological studies. We classified their requirements to complete the life cycle and to persist over time into three broad categories: floral rewards, places to reproduce and additional resources for food and nests. The life cycle requirements of peripheral pollinators differ significantly across insect orders. Hymenoptera and Lepidoptera have distinct life history requirements while Diptera and Coleoptera overlap in resource use. The three life history categories highlight how pollinators display different foraging behaviour, reproductive strategies of immature and adult stages, and the requirement of additional food resources used by larvae and adults beyond flower rewards to complete their life cycles. Knowledge about the requirements of neglected pollinators is a benchmark that can help to identify where efforts need to be made to conserve and maintain their biodiversity, even in small urban green spaces.

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.

Dendrothrips minowai Priesner, a significant pest in tea-producing regions of Asia, particularly China, damages tea plants (Camellia sinensis) by feeding on their tender leaves rich in polyphenols. Seven assembled genomes from the order Thysanoptera are currently available. This study presents the first chromosome-level genome assembly of D. minowai generated by PacBio Revio, Oxford Nanopore Technologies, MGI, and Hi-C technology. The assembled genome measures 350.11 Mb with 1269 contigs with a contig N50 of 536.34 Kb and a scaffold N50 of 16.86 Mb, organized across 19 chromosomes. A total of 16 730 protein-coding genes were identified, with 92.28% functionally annotated. The phylogenetic analysis reveals that D. minowai diverged approximately 103.2 million years ago, preceding all reported genomes of Thripidae species. Comparative genomic analysis identified 12 expanded and 172 contracted gene families of D. minowai, with expanded gene families linked to host plant metabolite processing and detoxification enzymes. Additionally, oligophagous thrips, D. minowai and Stenchaetothrips biformis, possess fewer chemosensory genes (gustatory receptors, odorant receptors, ionotropic receptors, chemosensory proteins, and odorant binding proteins) and detoxification genes (P450s, carboxyl/cholinesterases, UDP-glycosyltransferases) than polyphagous species (Frankliniella occidentalis and Thrips palmi). Interestingly, D. minowai exhibits an expansion in ABC transporter families, especially ABCG and ABCC, which is likely essential for detoxifying the high polyphenol content in tea plants. This study provides another genome sequence for oligophagous thrips species, which enriches the genomic data for further studies on the evolution, host adaptation, and novel control strategies of thrips. © 2025 Society of Chemical Industry.

Abstract Buleleng Regency is the largest grape production center in Bali, Indonesia. In addition to planting local grapes, farmers have recently started cultivating many introduced grape varieties as raw material for wine production. In tropical areas, grapes can be harvested three times each year, unlike in subtropical areas where grapes only bear fruit once a year, so pests and other insects are often found throughout the year. This research aims to determine the diversity of insects, both pests and predatory insects, on four introduced grape varieties: Colombard, Cabernet blanc, Solaris and Chenin blanc. The research was carried out in April-June 2024 at the Hatten wines vineyard, Buleleng district, Bali. This research was conducted using a survey method with yellow sticky traps and direct observation. The traps were placed diagonally across all plots of green grape varieties. A total of 40 traps were installed. Observations were conducted (from beginning of flowering until flowering 50% cap off) once a day for 15 days (or before fruit emergence). The results of the study showed that the types of pests found were included in the Order Thysanoptera, Diptera, Coleoptera, Lepidoptera, Acari, and Neuroptera. The diversity index showed a low value and the dominance index value was moderate. Direct observations also revealed several pest insects that were not caught in the yellow sticky traps but were present in the field, such as army worms and grasshoppers. Chrysoperla carnea is a natural enemy that acts as a predator. The adult C. carnea consumes nectar or pollen and is not predatory, but its larval stage is predatory. In the larval stage, C. carnea is capable of attacking pest insects from the order Thrips, Aphids, Mites, moth larvae, and some larvae of beetles and fruit flies. C. carnea is polyphagous and therefore does not have specific prey.

Aims: Cowpea (Vigna unguiculata (L) Walp.) is one of the most important grain legumes grown in all arid and semi-arid zones of Africa. Its production helps to combat malnutrition and poverty, and contributes to food self-sufficiency. However, its production comes up against numerous abiotic and biotic constraints, including floricultural insects such as thrips (Megalurothrips sjöstedti), which are small insects. They belong to the order Thysanoptera, family Thripidae, and cause considerable damage to cowpea crops, especially at flowering time. The aim of this study was to evaluate the behavior of eight lines from Burkina Faso compared with the thrips-resistant line (TVx3236) from the IITA collection (Nigeria). Methodology: A completely randomized block design with three replications in two trials (PT treated plot and PNT untreated plot) was used for the experiment. Results: Results showed that some varieties were resistant to thrips, while others were susceptible. The resistant genotypes were those with a low number of thrips per flower and high pod production. On this basis, KVx780-1 is the best genotype compared with KVx780-6 for varieties currently being popularized. Nafi variety is the best compared with the varieties popularized in 2012 (Nafi, Gourgou, Komcallé and Tiligré). Conclusion: In the case of the varieties that were previously popularized, the results confirmed the susceptibility of KN-1 variety, the tolerance of variety KVx165-14-1 and the resistance of the variety TVx3236.

Studies have identified 175 species on the Tamarix plant, with 41 species living in the plant stem, 28 species in the leaves, 4 species in the roots, 2 species in the flowers, and the remaining 100 species are found in the mixed parts.

The current paper has presented the stages of the development on plant protection study over 115 years and the history of the establishing and functioning of the laboratory for plant immunity since 1974 (50 years) at the Federal State Budgetary Scientific Institution “ARC “Donskoy”. There has been presented the papers of such specialists in plant protection and immunity as Cheskis F. N., Deyanov I.G., Shchegolev V. N., Makarova V. A., Pronicheva L. L., Chala V. A. and others, who began their research from the beginning of the last century till its second half. Taking into account the immunological characteristics in conditions of infectious disease backgrounds of varieties and parental forms, there have been developed new grain varieties, combining high productivity with resistance to a complex of local populations of the main diseases and strong immunity to pests. The heads of the laboratory for plant immunity and protection set up in 1974 were Georgievskaya N. A., Derov A. I., Derova T. G., Shishkin N. V. (who is a current head). In the field plot there were formed infectious disease backgrounds and backgrounds with high pest numbers using both generally accepted methods and new ones developed by the laboratory staff, where there were studied up to 25–30 thousand samples of various crops annually. The staff developed methods for forming backgrounds with high pest numbers, there were improved and proposed simpler and more accurate methods for insect counts. In order to estimate the number of corn bug larvae, there was developed and proposed a convenient productive screencollector, as well as methods for accounting for corn thrips using test tubes and plastic bags and methods for identifying wheat and barley grain damaged by pests. In different years, there were studied such crops as maize, perennial grasses, peas, soybeans, and rice for resistance to diseases and pests. The identified resistant varieties and samples were given to breeders for using them in breeding programs for immunity. Many employees are co-authors of the developed varieties of various crops.

Complete mitochondrial genome of two species of subfamily Panchaetothripinae, Astrothrips tumiceps (16,467bp) and Monilothrips kempi (14,773bp) are generated by Next-Generation Sequencing Method. In this study, the detailed annotation of these mitogenomes as well as comparative analyses are carried out to explore the codon usage, gene composition, andphylogenetic relationship of subfamilies of family Thripidae. Moreover, thegene rearrangement of subfamily Panchaetothripinae of family Thripidaeis also studied. Both the mitogenomes featured by 37 genes including 13 PCGs, 22 tRNAs, 2 rRNAs and with single putative control region with a positive AT-skew and negative GC-skew. trnS1 without DHU arm in both species, trnV without DHU arm in M. kempi, and trnE without TΨC loop in As. tumiceps. Further, codon based comparative analysis depicted the existence of natural selection pressure on all the PCGs in all the subfamilies of family Thripidae. The phylogenetic analyses, using the Bayesian inference (BI) and Maximum likelihood (ML) supported the monophyly of two suborders and family Phlaeothripidae. The family Thripidae is recovered as paraphyletic and subfamily Panchaetothripinae is in sister relationship with family Aeolothripidae and Stenurothripidae rather than the other subfamilies of family Thripidae. The gene order of the order Thysanoptera is highly rearranged, while few members of the subfamily Panchaetothripinae showed similar gene order to family Stenurothripidae. Therefore, this study suggests that the phylogenetic relationship between the subfamily Panchaetothripinae and other families is uncertain, necessitating a whole genome-based study to clarify the position of Panchaetothripinae within the suborder Terebrantia.

Microinsects are capable of associative learning and memory retention despite significant reduction in the number and size of neurons. Previously, the capabilities of Thrips tabaci (Thysanoptera, Thripidae) for associative learning and the formation of short-term memory have been demonstrated. In this study, an additional training session was added, as well as a time interval between them. Increasing the number of training sessions and spacing these out over time allowed us to demonstrate the persistence of memory traces for up to 24 hours. Thus, for the first time, the presence of consolidated forms of memory in the order Thysanoptera has been revealed.

We present here the first comprehensive checklist of Thysanoptera in Colombia. This study is based on a literature review, examination of specimens deposited in museums, and fieldwork conducted from 2012 to 2018 across various agroecosystems in the Andean, Caribbean, and Orinoco regions. Our study reports 38 new records of Thysanoptera for Colombia, bringing the total number of documented species to 183.

The status of arthropod diversity and biodiversity in Jakarta is often ignored, so the development of Plant Disturbing Organisms (Pests) is increasing. This has spurred farmers managing rice fields (Oryza sativa L.) to carry out unwise pest control on the remaining 414 hectares of land. The purpose of this study was to determine how the percentage of arthropod abundance based on order and fluctuations in arthropod populations on several rice fields in Cakung District, East Jakarta, and as information material in pest control based on Integrated Pest Management (IPM) that is appropriate in the field. The method used in this research is non-experimental with a direct survey method in the rice fields of the Maju Bersama (MB), Ujung Menteng (UM), dan Sawah Abadi (SA) in the vegetative planting phase until the harvest of rice plants. From the findings, the highest percentage of arthropod abundance was found in the order Diptera (36.73%), Araneae (19.45%), Hymenoptera (14.20%), Hemiptera (14.03%), Coleoptera (9, 32%), Lepidoptera (4.75%), Odonata (0.73%), Orthoptera (0.57%), Thysanoptera (0.07%), Heteroptera (0.05%), Dermaptera (0.05%), Isoptera (0.03%), and Psocodea (0.02%). Fluctuations in arthropod populations during one growing season increased starting from 6 - 8 MST, this is thought to be due to the use of various types of synthetic and sustainable pesticides that can affect the diversity of arthropods in rice fields. Therefore, it is necessary to conduct further research on the resistance level of pest arthropods to synthetic pesticides in rice fields.

Pollination is an ecological process that involves the transfer of pollen from the male to the female part of the flower with the help of various abiotic and biotic pollen dispersal agents and is an essential pre-requisite for fertilization and fruit/seed dispersal. Insects constitute one of the primary groups of pollinating agents, as the association between insects and flowers is well established. As flowers radiated so did the mouthparts of the insects exploiting them. Various insect groups, which are of prime significance in the pollination of agricultural and horticultural crops mainly belong to the orders Hymenoptera (bees, ants and wasps), Diptera (flies, mosquitoes, fungus gnats, midges), Coleoptera (beetles and weevils), Lepidoptera (moths and butterflies), Thysanoptera (thrips), Hemiptera (bugs) and Neuropteran (lace wing flies). This work is mainly based on detailed and through observations/study made from various cash crops viz., Brassica nigra, Coriandrum sativum, Tagetes erecta and Helianthus annuus from North 24 Parganas of South Bengal region.

For monitoring responses of insect arthropods to disturbance, a dataset of 1831 insects was considered. We studied faunal diversity of insects in terraces habitats located on the coast of Lebanon. Insects were sampled from 12 sites having different habitats with one sampling method of combined pitfall-pan trap. This study resulted in nine insect orders and 129 morphospecies. Hymenoptera was the most abundant order in all habitats (63.57%) followed by the orders Diptera, Homoptera, Coleoptera, Orthoptera, Hemiptera, Lepidoptera, Dictyoptera and Thysanoptera. This coast was classified with medium biodiversity index (D) of 0.51 for insect orders and high D of 0.83 for morphospecies. The highest (D) was in field crops habitat (H1) of 0.64 and 0.91 for insect orders and morphospecies, respectively; followed by scrublands (H3), greenhouse areas (H2) and olive orchards (H4). These results indicated that human intervention was affecting the diversity in natural habitats. Five insect orders: Coleoptera, Dictyoptera, Diptera, Hymenoptera, and Lepidoptera were significantly selected as potential biodiversity indicators in this coastal area. Thus, for monitoring these bioindicators, a protocol based on operating our combined trap method appears practical in design and yield very diverse material with the target of sustaining these insect populations in the coastal area.

Based on the results of phytosanitary monitoring (2008–2022), the species composition of pests in agroecosystems of radish (Raphanus sativus (L.) convar. radicula (Pers) Sazon.) in the central part of the Right-Bank Forest-Steppe of Ukraine has been specified. In radish crops, 59 species of phytophagous insects, two species of nematodes, and one species of slugs were identified. The harmful entomocomplex structure includes insects from 20 families of 8 orders. Representatives of the orders Coleoptera (17 species), Lepidoptera (16 species), and Homoptera (9 species) dominate the taxonomic structure, collectively occupying 71% in the structure of the harmful entomocomplex. Representatives of the orders Diptera and Orthoptera were presented by species from 6 and 5 families, respectively, and in the entomocomplex structure, they occupied 10% and 8%, respectively. The least species diversity was found for the order Thysanoptera, Hemiptera, and Hymenoptera, which collectively occupied 10% in the structure of the harmful entomocomplex. Sixteen constant species were identified (Plutella maculipennis Curt., Phyllotreta cruciferae Goeze, Phyllotreta undulata Kutsch., Pieris brassicae L., Agrotis segetum Denis&Schiff., Lacanobia oleracea L., Eurydema ventralis Kol., Brevicoryne brassicae L., Delia brassicae Bouche, Athalia rosae L., Delia platura Mg., Ceutorrhynchus quadridens Panz., Delia floralis Fallen, Thrips tabaci Lindeman, Entomoscelis adonidis Pallas, Evergestis extimalis Scop.), which caused significant damage to radish plants throughout the vegetation period. These species were trophically specialized, with 75% being oligophagous and 81% being phytophagous. Flea beetles such as Phyllotreta cruciferae Goeze, Phyllotreta undulata Kutsch., diamondback moth (Plutella maculipennis Curt.), cabbage aphid (Brevicoryne brassicae L.), turnip moth (Agrotis segetum Denis&Schiff.), and armyworm (Lacanobia oleracea L.) were found with high and medium frequencies in the studied agroecosystems, with population densities reaching maximum levels of 60–100% in some years.

Abstract: Thrips (Insecta: Thysanoptera) species in pepper fields was determined in Tokat Province, Türkiye in 2021-2022. The density of thrips began to rise once the leaves emerged in late May, and the collection of thrips species started in June to October. To conduct regular samplings of thrips that were infesting pepper fields, flowers were collected and placed in plastic tubes (50 ml) filled with ethyl alcohol at a concentration of 60%. The densities of thrips populations and the resulting damage caused by thrips attacks on different plant components (such as flowers, leaves, and fruits) were evaluated through the examination of a randomly chosen 25 samples for each plant part during each sampling period. The assessment encompassed various thrips families belonging to the order Thysanoptera, specifically, families, Thripidae, Aeolothripidae, and Phlaeothripidae. A total of 7 Thysanoptera species were identified in this study. The species were Frankliniella occidentalis (Priesner, 1932), Thrips tabaci Lindeman), 1895, Thrips meridionalis (Priesner 1926) and Chirothrips manicatus (Haliday, 1836) in Thripidae family, and Aeolothrips intermedius (Bagnall, 1934) and Aeolothrips fasciatus (Linnaeus, 1758) in Aeolothripidae family, and Haplothrips aculeatus (Fabricius, 1803) in Phlaeothripidae family. Both adult and larval thrips were collected mainly from the flowers sampled In this study, the dominant species was F occidentalis in pepper fields in Tokat Province.

The productivity of chili plants can be reduced due to the disturbance of various Plant Pest Organisms (OPT), one of which is insect pests from the Order Thysanoptera, family Thripidae or better known as Thrips sp. Thrips pests attack plants by sucking the liquid on the leaf surface, especially the young leaves. Symptoms that appear are silvery spots then change color to copper brown, the leaves curl or wrinkle and eventually the plant dies. Control measures that can be used to control or suppress Thrips sp. pest populations. other than using insecticides, namely by utilizing Biological Control Agents (APH) such as the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana. The fungus B. bassiana infects host insects through physical contact by attaching conidia to the integument. M. anisopliae infection begins with the attachment of M. anisopliae spores to the cuticle of the insect and then the spores of M. anisopliae germinate and penetrate into the insect's body. This study used a field experiment method arranged in a Factorial Completely Randomized Design (CRD) with 2 factors and 4 replications. The first factor was the type of entomopathogenic fungus which consisted of two levels, A1 = Beauveria bassiana, A2 = Metarhizium anisopliae. The second factor was the density of conidia which consisted of 4 types: K1 = 105/ml, K2 = 106/ml, K3 = 107/ml, K4 = 108/ml. The observed data is quantitative data, then it will be analyzed statistically using ANOVA analysis of variance, if there is a significant difference then a follow-up test will be carried out using the DMRT. The effect of factor A1 (B. bassiana) is better than the effect of factor A2 (M. anisopliae) on the mortality of Thrips sp. and the best effect of factor K is on K4 (spore density 108/ml). So it is recommended to use the A1K4 treatment because it is effective on the mortality of Thrips sp. and the effect of factor K4 (spore density of 108/ml) was better than the effect of factors K1 (spore density of 105/ml), K2 (spore density of 106/ml), and K3 (spore density of 107/ml) on the intensity of attack of Thrips sp. So it is recommended to use the K4 treatment because it is effective against the intensity of attacks of Thrips sp.

Tobacco (Nicotiana tabacum L.) is an important industrial crop from the Solanaceae family cultivated for its leaves in approximately 100 countries worldwide. In South Africa (SA), tobacco is grown in five of its nine provinces: Limpopo, North West, Western Cape, Eastern Cape, and Mpumalanga. The producer price for unmanufactured tobacco is approximately US$3570/ton annually (FAO, 2021). Emerging and recurrent plant viruses such as tomato spotted wilt orthortospovirus (TSWV) have seriously affected tobacco production yield and quality. Between November 2018 to April 2019 growing season, large thrips (order Thysanoptera) populations were observed in tobacco fields throughout South Africa's major tobacco-growing areas, and plants were showing severe necrosis, yellowing, stunted growth, ringspot, and leaf curling symptoms, which are usually associated with plant virus infections. The disease incidence was estimated at 30%, as per visual observations. Twenty-two symptomatic leaf tissue samples were collected from tobacco farms in Limpopo, Northwest, and Western cape provinces. Samples were initially screened using the double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) with LOEWE®Fast Kit (LOEWE®, Germany), which detectsTSWV, groundnut ringspot orthotospovirus (GRSV), and tomato chlorotic spot orthotospovirus (TCSV). Nineteen of these samples tested positive for orthortospoviruses. Subsequently, a reverse transcription-polymerase chain reaction was performed on all ELISA-positive samples using orthotospovirus-specific primers gM410 & gM870c targeting the NSm gene (Chen et al., 2012). All samples were positive for orthotospoviruses, as indicated by the presence of a 500bp amplicon. Nineteen purified PCR products were sequenced in the forward and reverse directions using Sanger sequencing at the KwaZulu-Natal Research and Innovation Sequencing Platform (KRISP; South Africa). The sequences were aligned using Muscle in MEGA version X (Kumar et al., 2018) to generate the consensus sequences that were then subjected to the standard nucleotide basic local alignment search tool (blastn) on the NCBI website. Blastn analysis showed that 16 of the 19 samples matched TSWV nucleotide sequences, while three of the sequences; LP14 (accession number OL505552), LP18 (accession number OL505553), and NW4 (accession number OL505554), had a nucleotide sequence identity of 96,38%, 96,97% and 97,29% with the GSRV isolate SA-05 (accession number MH742957; Silva et al., 2019) from South Africa, respectively. This is the first report of GRSV infecting tobacco after TSWV was reported in SA. Previously, GSRV was reported on soybean and groundnut in South Africa by Petersen and Morris in (2002) and Silva et al. in (2019). The results from this study lay a foundation for more detailed studies on GRSV, which will result in the development of effective and sustainable control strategies to manage GRSV diseases on tobacco in SA.
