In the field, double infections of two or more viruses are the rule, not the exception. The presence of several viruses in a plant makes it difficult to interpret virus-insect vector-plant interactions. Mixed infections can alter plant symptoms compared with single infections and may also impact their vectors. We describe plant-mediated indirect effects of virus double-infection on feeding behavior of an aphid vector (Aphis gossypii Glover) and virus transmission in melon (Cucumis melo L.). The viruses we used were a circulative cucurbit aphid-borne yellows virus (CABYV, Solemoviridae:Polerovirus) and a non-circulative cucumber mosaic virus (CMV, Bromoviridae:Cucumovirus). When melon plants were CMV-infected, indirect plant-mediated effects on A. gossypii feeding were like those reported on other plant species; specifically, intracellular punctures (pd) were more frequent and longer than on mock-inoculated plants, which enhanced CMV transmission. Similarly, when plants were CABYV-infected, we observed a statistically non-significant trend for increases in extended salivation (E1) and ingestion (E2) activities in phloem compared with mock-inoculated plants, which also enhanced CABYV transmission. When aphids fed on CMV-CABYV double-infected plants feeding behavior activities related to the transmission of both viruses were enhanced even more than when feeding on single-infected plants. Nevertheless, the virus transmission rate was the same on single-infected or double-infected plants. Thus, our results suggest that double infections do not modify viral dispersion compared with single infections since the indirect effect of CMV and CABYV in single infections is already optimized to favor virus transmission.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"25 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11842303/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143468314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies examining the host range of A. hagenowii have largely focused on cockroaches of economic and medical importance, which represent a minority of species in an order filled with species of diverse morphology, behavior, and ecology. The aim of this study was to expand the known host range of A. hagenowii with emphasis on nonpest as well as pest species from 3 cockroach families (Blattidae, Corydiidae, and Ectobiidae). Previously recorded host species were also reexamined. Oothecae from 17 cockroach species were exposed to A. hagenowii. Three new host species were recorded: Blatta lateralis (Walker) (Blattidae), Neostylopyga propinqua (Shelford) (Blattidae), and Parcoblatta fulvescens (Saussure and Zehntner) (Ectobiidae). Among the reexamined host species Periplaneta australasiae (Fab.) (Blattidae), Blatta orientalis L. (Blattidae), and Neostylopyga rhombifolia (Stoll) (Blattidae) were successfully parasitized. The cuticle thicknesses of 7 cockroach species' oothecae were also investigated. There were significant differences [Kruskal-Wallis: each zone (below keel, side, and bottom) measured P < 0.001] in cuticle thickness among the species measured. Polyphaga sassurei (Dohrn) (Corydiidae) and Eurycotis floridana (Walker) (Blattidae) had the thickest cuticles (each zone >0.09 mm) and Blattella germanica (L.) (Ectobiidae) had the thinnest (each zone <0.03 mm). However, the mean A. hagenowii ovipositor length (0.92 mm ± 0.01 mm) far exceeded the thickest oothecae measured.

Whereas traits like growth and adult size are often heritable and are passed on from one generation to the next, these can be significantly affected by the quality and quantity of resources provided by one or both parents to their offspring. In many vertebrates, such as birds and mammals, parents raise their young until adult, providing food, shelter, and protection. On the other hand, in insects, there is often little or no parental care, and the young are left to fend for themselves. Despite that, some insects can enhance the growth of their offspring. In parasitoid wasps, for example, mothers inject biochemical factors, including venoms, teratocytes, and virus-like particles into the host that increase host quality by regulating the nutritional milieu. However, it is not known whether maternal size is positively correlated with host regulation. Here, we evaluate maternal and host size-related effects on the development of an asexually reproducing (= female only) secondary idiobiont ectoparasitoid, Gelis agilis on pre-pupae in cocoons of its host, the primary parasitoid, Cotesia glomerata. Females G. agilis from 2 adult size classes, \"small\" (mean 0.7 mg) or \"large\" (mean 1.2 mg), were allowed to parasitize cocoons of differing size along a continuum from ~1.2 mg to ~4.0 mg, and the body size and development time of their offspring were measured. In both body size classes of G. agilis mothers, there was a strong correlation between host size and offspring size. However, there was no effect of adult G. agilis size on this parameter: for a given host size, the size of G. agilis offspring did not differ between small and large mothers. Our results reveal that host quality is mostly pre-determined, irrespective of maternal size.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"25 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11756310/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143023823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we documented aspects of the life history of the backswimmer Notonecta indica L. in Jamaica and quantified its consumption of Aedes aegypti (L.) larvae throughout development and at different mosquito densities. The egg and fifth nymphal stages had the longest mean development times while the third nymphal stage had the shortest. Development was noted to be shorter in N. indica when compared to other backswimmer species from different climates, likely due to higher temperatures and greater food availability in the present study. Daily mosquito consumption increased exponentially throughout nymphal development. Individual adults displayed significant variation in daily mosquito consumption, and consumption was found to be directly proportional to mosquito density. Backswimmers may contribute to mosquito suppression and the reduction of mosquito-borne diseases, but their contribution is likely limited by the spatial and temporal differences between backswimmers and mosquitoes, namely, in habitat preferences, dispersal patterns, and development times.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"25 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11815496/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, identifying the flowering plant families driving the abundance of Sphaerophoria scripta Linnaeus, 1758, is essential to promote its presence and abundance. Here, we described the flowering plants present in the vegetation cover of olive groves and studied how these flowering plant families shape the abundance of S. scripta. A total of 90 plant species belonging to 20 families were identified. Asteraceae was the dominant flowering family, followed by Poaceae. The generalized linear model showed that the presence of flowering plants of the families Campanulaceae, Asteraceae, Orobanchaceae, and Plantaginaceae in the ground-cover vegetation promotes the abundance of S. scripta in olive groves. Conversely, flowering plants of the families Poaceae and Polygonaceae were associated with the decreased abundance of this syrphid species. Our results suggest that increasing particular plant families and decreasing others in the ground-cover vegetation may favor S. scripta abundance in the Mediterranean olive groves.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"24 6","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11604070/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142739667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to understand the proteomic changes of honeybees under heat stress to understand the molecular mechanism behind heat resistance. However, the proteomic changes of honeybees under heat stress are poorly understood. We analyzed the proteomic changes of Apis mellifera Ligustica (Hymenoptera: Apidae) under heat stress using mass spectrometry-based proteomics with TMT (Tandem mass tags) stable isotope labeling. A total of 3,799 proteins were identified, 85 of which differentially abundance between experimental groups. The most significant categories affected by heat stress were associated with transcription and translation processes, metabolism, and stress-resistant pathways. We found that heat stress altered the protein profiles in A. mellifera, with momentous resist proteins being upregulated in heat groups. These results show a proof of molecular details that A. mellifera can respond to heat stress by increasing resist proteins. Our findings add research basis for studying the molecular mechanisms of honeybees' resistance to heat stress. The differentially expressed proteins identified in this study can be used as biomarkers of heat stress in bees, and provide a foundation for future research on honeybees under heat stress. Our in-depth proteomic analysis provides new insights into how bees cope with heat stress.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"24 6","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11599371/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142729670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mitogenome size ranged from 15,193 bp in Onukigallia onukii (Matsumura, 1912) to 15,986 bp in Multinervis guangxiensis (Li and Li, 2013), they all contained 37 genes, and gene order was similar to that in other leafhoppers. Nucleotide composition analysis showed that the AT content was higher than that of GC, and the protein-coding genes usually ended with A/T at the 3rd codon position. The Ka/Ks ratio showed that the CYTB gene has the slowest evolutionary rate, while ND4 is the gene with the fastest evolutionary rate. Relative synonymous codon usage analysis revealed the most frequently used codon was UUA (L), followed by CGA (R), and the least frequently used codon was CCG (P). Parity plot and neutrality plot analyses showed that the codon usage bias of mitochondrial genes was influenced by natural selection and mutation pressure. However, natural selection plays a major role, while the effect of mutation pressure was small. Effective number of codons values were 40.15-49.17, which represented relatively low codon bias.

These plant defenses provide numerous opportunities to integrate chemical ecology into IPM programs, including changes to a plants volatile profile. In this laboratory study, we provide evidence that elicitors which mimic jasmonic acid (JA) and salicylic acid (SA) can be used to attract or repel L. decemlineata respectively. Adult beetles are highly attracted to potato plants sprayed with the JA mimicking elicitor Blush 2X, while plants sprayed with SA mimicking elicitor, Actigard 50WG, appear to be repellent.

A potentially promising pathway is improving biological control by natural enemies through the timely application of selective insecticides. In our study, adult predators were exposed to commercially available insecticides (cyantraniliprole and pyriproxyfen) using a combined laboratory and field approach to assess their effects on survivorship and predation. We isolated 2 predators, Hippodamia convergens Guérin-Méneville and Geocoris punctipes (Say), in the laboratory to estimate the survivorship and consumption of whitefly nymphs, Bemisia tabaci (Gennadius). In the field, we deployed whitefly nymph-infested potted cotton plants in replicated cotton plots with both insecticide treatments. We enumerated whitefly nymph populations on enclosed (predator-exclusion) and open (predator-accessible) potted plants. While pyriproxyfen had a negligible effect on the predators, cyantraniliprole exposure directly affected H. convergence by reducing survivorship duration and indirectly influenced both predators by reducing prey consumption and altering the consumption of alternative prey. In field conditions, regardless of pesticide exposure, whitefly-infested potted plants that excluded predators had more whiteflies than predator-accessible potted plants. Overall, pyriproxyfen demonstrated minimal impact on the predators in the laboratory or field, while cyantraniliprole adversely influenced mortality and indirect foraging under controlled laboratory conditions but did not have a significant impact in the field.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"24 6","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11576360/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142675986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
