However, the mechanisms by which habitat heterogeneity and seasonal dynamics drive parasitoid communities remain poorly understood. We examined egg parasitoid diversity, abundance, parasitism rates, and interaction network structure across seminatural Masson pine forests and 3 crop habitats (tea plantations, plum orchards, tobacco fields). Sentinel egg cards of Antheraea pernyi (Guérin-Méneville) and Samia ricini (Jones) were deployed monthly from April to November over 2 consecutive years. Parasitoid diversity was strongly determined by habitat type, with seminatural habitats supporting higher species richness and diversity. Parasitoid abundance and parasitism rates were shaped by habitat type, season, and host egg type. Species-habitat network analyses revealed a highly modular structure dominated by peripheral species, with few connector species, indicating strong habitat-filtering and functional specialization. Complex seminatural habitats sustained stable modular networks and higher parasitoid activity, while intensively managed crop habitats exhibited weaker connectivity and greater temporal variability. Our findings demonstrate that parasitoid community dynamics and biocontrol efficacy are closely linked to habitat heterogeneity, seasonal resource availability, and network structure. Alternative hosts sustain parasitoid activity and enhance network stability, supporting biological control. Maintaining a mosaic of crop and seminatural habitats is critical for preserving parasitoid network integrity and improving the stability and effectiveness of biological control services.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148548122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studies using molecular gut content analysis to detect pollen-feeding in generalist predators are exceedingly rare. Pollen-feeding is known to be important to the nutritional ecology of many generalist predators and is particularly well studied in phytoseiid mites. In apples, generalist phytoseiids such as Typhlodromus caudiglans Schuster (Mesostigmata: Phytoseiidae) and the stigmaeid predator, Zetzellia mali (Ewing) (Trombidiformes: Stigmaeidae), feed on both pest mites and pollen trapped on foliage. It is unknown whether these mites commonly pollen-feed or if they exhibit in-field preferences for pollen type. To detect likely pollen-feeding in these predatory mites, we sampled tree foliage and the ground cover (vacuum sampling) from an apple orchard for 9 weeks in 2019 and 2020, and plant DNA was detected through metabarcoded gut content analysis using the trnF and internal transcribed spacer 2 (ITS-2) regions. We detected DNA from 31 plant genera in our samples. Malus was the most common taxon, followed by Pinus, Brassica, Festuca, and Lactuca. Forty-six percent of phytoseiid and 34% of Z. mali samples were positive for non-Malus DNA. Changes in detection of several taxa (Pinus, Festuca, Hyoscyamus, Citrullus, Poa, and Solanum) throughout the monitoring period likely reflected temporal variation in pollen availability. Pollen availability may play a role in determining the composition of predatory mite communities. Metabarcoding to detect possible pollen-feeding has the potential to improve our understanding of the role of floral resources in conservation biological control.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148789748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Removal of an invasive ant may therefore promote recovery of local biodiversity. However, evidence for such effects is mixed, and often taxon-specific. In this study, we experimentally removed Pheidole megacephala (Hymenoptera: Formicidae) from 2 secondary forest sites at located at Taiping (TP) (herein referred to as TP1 and TP2) and examined the taxon-specific responses of native ants, beetles, and spiders under field conditions. Removal of P. megacephala had limited effects on ant species richness and Shannon diversity. In contrast, beetle family richness at TP1 increased significantly during the first year of posttreatment compared with pretreatment levels. Several native ant species (eg Carebara diversa, Recurvidris recurvispinosa, and Solenopsis indagatrix) and predatory beetle taxa (Harpalinae, Cetoniinae, Paederinae, and Staphylininae) that were absent before treatment were detected following P. megacephala removal. Spider family richness declined during the second year of posttreatment at TP2, whereas the activity density of hunting spiders, particularly Ctenidae, Oonopidae, and Salticidae, increased approximately 2-fold at TP1 after removal. These native ants, predatory beetles, and hunting spiders that responded positively to removal share similar food resources or overlapping nesting and foraging habitats with P. megacephala. Our results suggest that removal of this invasive ant may have facilitated partial recovery of the local invertebrate community, particularly taxa that are ecologically and behaviorally similar to P. megacephala, likely by releasing food and spatial resources.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148577446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although research has increasingly focused on Lepidoptera, many of which are important pest species, key aspects of their microbiome's stability and functional importance remain ambiguous and seem context-dependent. The caterpillars of the goat moth, Cossus cossus (Linnaeus), which develop over 2 to 5 years within trunks of deciduous trees and consume a wood-based diet rich in recalcitrant lignin, provide an intriguing model to examine potential microbial contributions to lignocellulose degradation. Full-length 16S rRNA gene sequencing revealed a gut microbiome dominated by Enterococcus spp. and a high Leuconostoc spp. presence in the mandibular glands. Concurrent culturomics approaches recovered 64 taxa identified by sequencing and uncovered additional diversity, such as Brevibacterium spp. and Streptomyces spp. Notably, several isolates, including strains of Acinetobacter johnsonii, Citrobacter gillenii, Leucobacter sp., and Pseudomonas sp., demonstrated growth on minimal media supplemented with wood, lignin, or lignin-derived aromatics as the sole carbon and energy sources. These findings provide the first evidence that specific bacterial members of the goat moth caterpillar's microbiome may contribute to wood digestion, suggesting a functional symbiosis suited to a challenging dietary niche.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148600701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, Colias philodice Godart and C. eurytheme Boisduval (Lepidoptera: Pieridae) hybridize when their ranges are in contact or overlap and are commonly found in large cities throughout North America. However, it is an open question how variation in urbanization might affect variation in hybridization. Using wild Colias across a gradient of urbanization in Toronto, Ontario, we tested how the variation in Colias color, as an indicator of hybridization, relates to human disturbance and urbanization. We created an objective numeric classification for both C. eurytheme and C. philodice, against which we categorized Colias samples. We found that some of the metrics, including distance to road, ordinal date, and number of pedestrians affect the variation in Colias color, suggesting that urbanization affects Colias coloration, and potentially rates of hybridization, in Toronto.

Synergistic interactions between pesticides and poor nutrition may exacerbate individual effects, but how these anthropogenic stressors interact remains poorly understood, particularly across understudied life phases. Queen bumblebees in temperate regions emerge from hibernation in spring and attempt to initiate a colony. In agricultural environments, queens typically emerge during (i) a carbohydrate \"hunger gap,\" whereby nectar demand is higher than supply and (ii) during a time of year in which pesticide use is high. Here, we assessed the impact of carbohydrate limitation and exposure to the novel insecticide flupyradifurone on colony initiation of wild-caught bumblebee (Bombus terrestris) queens. Using a fully crossed experimental design, queens were exposed to a field-realistic concentration of flupyradifurone (1.6 ppm) at high (50% (w/w)) or low (15% (w/w)) sucrose concentrations. We found that bees provided with low-sucrose concentrations produced no eggs or larvae compared with 31.6% in the high concentration groups. Queens fed a lower concentration of sucrose also developed smaller ovaries and performed less nest initiation behaviors. We also found that exposure to flupyradifurone increased the activity of bumblebee queens, and that carbohydrate limitation and flupyradifurone synergistically reduced the likelihood of nest initiation behavior. These results demonstrate the importance of carbohydrate intake during the spring when queens are founding colonies, highlighting the need to consider not only floral diversity within environmental land management schemes but also floral quality.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13493054/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148789751","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}

Here, we exposed queenless microcolonies of the buff-tailed bumble bee Bombus terrestris (L.) to field-realistic concentrations of copper (692 µM) or cadmium (7.38 µM), and assessed their effects on sucrose syrup consumption, worker survival, egg-laying event and brood development. We also quantified metal concentrations in larval and prepupal tissues to investigate potential metal excretion during development. Copper, but not cadmium, had detrimental effects on microcolony performance, as shown by reduced worker survival, delayed egg laying and impaired brood development. Workers exposed to copper also reduced their consumption of contaminated sucrose syrup, suggesting a possible behavioral avoidance to mitigate toxicity. In addition, metals were found at higher concentrations in larval than in prepupal tissues, indicating that metal excretion likely occurs at the larval-pupal interface. Overall, our study strengthens current knowledge on the effects of trace metals in social bees and provides evidence for a potentially important excretion process occurring during larval development.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148629884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
