Our aims were to: (1) document the species diversity of Mexican Sphingidae; (2) generate spatial distribution models for sphingid species; and (3) discuss distributional patterns and the conservation implications for key taxa that, due to their life-history characteristics and restricted distributions, may require conservation actions. We compiled a total of 9,985 records representing 202 taxa (185 species and 17 subspecies) in 49 genera and three subfamilies-Macroglossinae, Sphinginae, and Smerinthinae. We report Perigonia odileae Haxaire & Melichar, 2025, and Perigonia pallida Rothschild & Jordan 1903, as new Sphingidae records for the Mexican realm. Species distribution models indicated that most sphingid genera in Mexico have a predominantly Neotropical biogeographic affinity: 12 genera (24%) exhibit a Neotropical distribution, seven (14%) are exclusively Nearctic, eight (16%) occur in both regions, and 22 (45%) are largely Neotropical but extend marginally into the Nearctic. We discussed taxonomic and distributional considerations for taxa that represent confirmed species (based on barcoded specimens in BOLD), along with species records representing significant expansions into the Mexican realm. Maintaining a network of threatened ecotopes-such as cloud forests and tropical rainforests-will be crucial for preserving sphingid populations and for promoting population (re)colonization processes.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13557777/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148920027","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}

The increasing frequency and intensity of antimicrobial chemical use in agricultural systems disrupts the environmental microbial community and has been linked to bee declines. However, it remains largely unknown how pesticides and antimicrobial agents vary across the landscape, and in turn, cascade to alter microbiome assembly in solitary bees. To evaluate landscape-level effects of pesticide contamination on the pollen microbiome of solitary bees, we surveyed Osmia cornifrons (Hymenoptera: Megachilidae Radoszkowski, 1887) pollen provisions across 3 contrasting land use types in central upstate New York: forest, urban, and orchard habitats. Pollen provisions were screened for 94 common pesticides and sequenced to characterize their bacterial community. We found pesticide concentrations and risk varied significantly across land use types and was highest at orchard sites. Microbial communities also differed across landscapes, with increased surrounding forest cover corresponding to higher abundances of Apilactobacillus, a beneficial bee-associated genus in the family Lactobacilliacea. We found a significant correlation between increased pesticide concentration and decreased pollen-associated microbial diversity. These results indicate links between land use, pesticide exposure, and the microbiome of solitary bees.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13645432/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149127768","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 this study, the effects of Dentamet exposure on the composition and structure of the B. oleae bacterial community were evaluated by comparing flies from treated (Dentamet-treated [DT]) olives, with untreated (non-treated [NT]) olives under laboratory conditions, and olives collected from untreated orchards (wild-in-controlled-environment). Bacterial communities were characterized by 16S rRNA gene sequencing on an Illumina MiSeq platform, and quantitative Real-Time PCR (qPCR) was used to estimate the abundance of Ca. E. dacicola and 4 additional bacterial genera involved in detoxification and nutrient metabolism. Metabarcoding analyses revealed differences between DT and NT samples, including reduced bacterial diversity in DT larvae and a shift in the adult bacterial community structure supported by beta diversity analyses. qPCR analysis showed a lower abundance of Ca. E. dacicola in DT larvae (significant), pupae, and adults, alongside decreases in the 4 investigated bacterial genera. Overall, these findings suggest that Dentamet exposure is associated with changes not only in the primary symbiont but also in the broader bacterial community, with potential implications for key microbial interactions.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13633668/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149110878","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}

These advances are particularly important in the face of climate change, pesticide resistance, and the growing need for sustainable agricultural intensification. This review synthesizes how machine learning can be applied across the semiochemical discovery and implementation pipeline, from chemical signal detection to field deployment and decision support for integrated pest management. We review major machine learning approaches and demonstrate how they extract biologically relevant information from high-dimensional chemical, electrophysiological, behavioral, sensor, and field datasets. These methods accelerate semiochemical discovery, prioritize candidate compounds, optimize formulations and deployment strategies, and support adaptive pest management under dynamic environmental conditions. We further examine the integration of sensor-based technologies, explainable machine learning, and optimization algorithms to improve pest detection, monitoring, and intervention. Current challenges include data scarcity, heterogeneous datasets, the lack of benchmark resources, limited field validation, and the underrepresentation of tropical agroecosystems and smallholder farming systems. We propose practical recommendations for developing reusable datasets that integrate volatile profiles, electrophysiology, insect behavior, and management outcomes to improve model robustness and reproducibility. Central to this review is a 4-stage framework comprising detection, design, deployment, and decision support that connects machine learning with chemical ecology and provides a practical roadmap for translating computational advances into targeted, efficient, and sustainable pest management.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13537533/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148880702","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}

EAB is best managed via insecticides and biological control by wasps and woodpeckers. Neonicotinoids are often used for EAB due to cost and ease of use but are becoming restricted worldwide and are toxic to beneficial insects. Anthranilic diamides, a newer insecticide class, can manage beetle larvae with limited off-target effects. If diamides control EAB, they could replace neonicotinoids. We tested if drenches of chlorantraniliprole and cyantraniliprole at 3 rates controlled EAB larvae without affecting parasitoids in 41 recruit-sized white ash, Fraxinus americana L. (mean ± SE = 11.0 ± 0.7 cm diameter at breast height (DBH)) in central Kentucky 6 months after application. Only the high chlorantraniliprole rate (0.157 g a.i./L per cm DBH) significantly reduced EAB densities (1.3 ± 0.5 larvae per m2) relative to controls (9.5 ± 4.2 larvae per m2). Three treatments reduced parasitism by Phasgonophora sulcata Westwood relative to controls while no treatment affected nonnative parasitism or woodpecker predation. Thirty-six percent of larvae were parasitized even though the nearest parasitoid releases were over 20 km away and occurred 7 years prior. Spathius galinae Belokobylskij & Strazanac parasitism, never released in Kentucky at the time of this project, averaged 7.8 ± 2.9 % and is the furthest south this species has established in the United States.

Though low-abundance archaeal, fungal, and viral sequences were detected, bacterial taxa (>89% of annotated genes) dominated functional profiles.

Population-specific taxa were most abundant in MDJ (19 species), followed by PB (15), with SC harboring only 1 unique species. Predicted functional profiles aligned with taxonomy: PB showed elevated amino acid/carbohydrate metabolism, carbohydrate-active enzyme, and efflux pump gene abundances.

A. eugenii is a pest in both field and greenhouse pepper production across North America, with field production generally impacted in Central America, Mexico, the southern United States, and Hawaii, and greenhouse production being impacted in the northern United States and Canada. The life cycle of A. eugenii primarily occurs inside a pepper fruit, protecting these stages from contact-based insecticidal sprays. Only the adult stage is susceptible to chemical management strategies. However, these strategies are expensive to growers and have negative impacts on agroecosystems, presenting a critical need for new management strategies such as initial oviposition deterrence. Female A. eugenii produce an oviposition-deterrent pheromone (ODP) after egg-laying, indicating to other females the pepper has been occupied. This study evaluated the initial oviposition deterrence of kaolin clay in combination with dye and a previously characterized A. eugenii ODP. Results indicated that peppers treated with kaolin clay alone deterred oviposition, but a concentration of 10% ODP + kaolin clay further reduced oviposition events. When peppers were treated with red-dyed kaolin clay, the rate of oviposition was also decreased as compared to kaolin clay alone. Further investigations of dyed and ODP-infused kaolin clay should be conducted under greenhouse and field conditions to evaluate their effectiveness against initial oviposition in traditional agricultural settings.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13543681/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148891797","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}

To assess the effects of H. defensa, naturally infected cowpea aphids with this bacterium (Hd+) were treated with a combination of antibiotics to eliminate the symbiont, generating uninfected cowpea aphids (Hd-). The results showed that A. colemani had similar parasitism success in Hd+ and Hd- cowpea aphids, suggesting that H. defensa had a limited effect on the overall parasitism success of this species. However, H. defensa significantly prolonged the time to mummification of A. colemani developing in Hd+ aphids, while post-mummification emergence and the mummification-to-emergence interval were not significantly affected. In P. volucre, H. defensa had a strong negative effect on parasitoid performance. Hd+ aphids showed significantly lower parasitism success and post-mummification emergence, together with significantly longer time to mummification and mummification-to-emergence interval.

A total of 402 lice were sampled, of which 27 specimens were selected for detailed morphological, molecular, and phylogenetic analyses. Molecular characterization based on mitochondrial markers (cox1, cob and 12S) revealed a specific pattern of genetic diversity, identifying two distinct clades (A and B), with low sequence similarity between them, and clade B predominating in the sampled population. Geometric morphometric analyses revealed significant global size differences between clades A and B, with clade B lice being the largest specimens. All analyzed lice carried three mutations (M815I, T917I and L920F) in the voltage-sensitive sodium channel (VSSC) gene, indicating fixation of alleles associated with permethrin resistance. These findings provide preliminary evidence of permethrin resistance-associated mutations in head lice from Seville and underscore the need for larger studies to determine their frequency and epidemiological significance. Moreover, this study represents the first molecular characterization of head lice in this region and supports the combined use of morphometric and molecular approaches to better understand lice diversity and resistance patterns.","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"26 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13628266/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149110884","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}
