In agricultural systems, field edges often concentrate insect pests and their associated damage, yet whether edge aggregation enhances pest performance or creates density-dependent constraints remains unclear. We investigated this relationship in the North American tree fruit pest, plum curculio, Conotrachelus nenuphar (Coleoptera: Curculionidae), by quantifying pest spatial distribution, fruit injury, and reproductive performance in a 4.2-acre peach orchard containing 355 trees (Prunus persica var. \"Fantasia\"). Between 19 May and 25 August 2025, we measured adult abundance, feeding injury, oviposition scars, larval abundance and emergence, and larval mass across trees and then evaluated density-dependent effects on adult injury behavior using no-choice bioassays. Although adult abundance was evenly distributed throughout the orchard, feeding injury, oviposition scarring, and larval abundance were concentrated along orchard edges. Increased oviposition at edges produced greater larval abundance and density than in interior trees, demonstrating enhanced reproductive output. However, larvae from edge fruit were smaller on average, suggesting density-dependent constraints on offspring development. No-choice bioassays supported these patterns, with doubled adult densities increasing feeding injury by 38%. Edge-associated pest pressure was linked with reduced fruit yield, with damage increasing and yield declining from the orchard interior toward the edge. Together, these findings demonstrate that orchard edges promote pest reproductive output through spatial aggregation while density-dependent constraints emerge at high larval densities.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148976092","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}

Despite their necessity within the agriculture industry, they remain one of the most understudied groups of insects. Non-crop habitats adjacent to farmland provide critical ecological services for these beneficial insects and can act as a corridor from uncultivated land to fields; this interaction is a form of edge effect. Here, we evaluate how 3 types of non-crop field edges affected the diversity, richness, and abundance of parasitoid hymenopterans at varying edge distances in canola (Brassica napus L.; Brassicales: Brassicaceae). We also compiled all sampled genera into a survey of parasitoid Hymenoptera found in southern Alberta canola. We conclude: (1) non-crop boundaries have a weak effect on parasitoid communities within our study system; (2) variability in parasitoid diversity and composition was most pronounced among farms, suggesting a dominant role of farm management practices; (3) parasitoid diversity is highest at edge boundaries and decreases toward the field interior; (4) Diolcogaster spp. (Hymenoptera: Braconidae)-predominantly Diolcogaster claritibia Papp, first reported in Canada in 2014-was the dominant group of parasitoids in these fields, comprising 74% of collected specimens. Overall, the composition of parasitoid communities is likely more sensitive to individual farm management practices or landscape composition and configuration, rather than to the type of bordering non-crop habitat. Further research is needed to determine which of these farm-level drivers are influencing parasitoid communities.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13622337/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149079726","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 mitigate these phenomena, forest managers are increasingly employing forest fuels management operations (tree thinning and prescribed fires) to reduce fire severities and inter-tree competition for water and soil nutrients. While such forest restoration programs have proven effective, the impacts on forest arthropod communities are largely unreported. In this 6-year case study, we examined the response of a surface-active (epigeic) beetle community (Coleoptera) in a mixed-conifer forest subjected to tree thinning followed by a prescribed broadcast slash burn. We used a Before-After/Control-Impact (BACI) design to test treatment effects on the beetle community composition, diversity, richness, evenness, individual species abundances, and trophic structure. We documented 289 taxa of Coleoptera and found that treatments caused significant changes in the beetle community's composition, with 21 common species increasing and 35 species declining in the more open post-treatment sub-canopy environment; only 3 common species were extirpated from the treatment sites, while 2 common species colonized the post-thinned/burned areas. Saproxylic species exhibited a decrease compared to controls after thinning and prescribed fire. Trophic structure species composition did not change, although numbers of individuals increased in the omnivore, fungivore, and detritivore trophic groups. Overall, our forest restoration treatments did not reach the level of impact from more severe forest disturbances (clear-cutting, or high-severity wildfires) and created a mosaic of grassy forest understory and small open meadow patches that would contribute to increased landscape arthropod diversity.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13585400/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148988348","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}

We evaluated the potential host range of S. tridentata by testing 4 elm species (Ulmus glabra, Ulmus laevis, Ulmus minor, and Ulmus pumila), 3 maple species (Acer campestre, Acer platanoides, and Acer pseudoplatanus), and 3 poplar species (Populus alba, Populus nigra, and Populus tremula) that are widespread in Europe. No-choice and choice feeding bioassays were conducted to assess adult feeding preference, while no-choice development bioassays were performed to determine whether larvae could establish and develop within logs of the tested species. Adults fed on all elm species but showed no feeding activity on maples or poplars. Feeding levels on European elms did not differ significantly from those recorded on the primary North American host, U. americana. Larvae were recovered from logs of all 4 European elm species, confirming their suitability for larval establishment, whereas no larvae were found in maple or poplar logs. Adult emergence was limited, with only 3 individuals emerging from U. minor logs. Our results indicate that European elm species can support both adult feeding and larval development of S. tridentata, whereas the tested maple and poplar species appear to be unsuitable hosts.

Wildflower plantings are promoted as conservation strategies to support pollinators and natural enemies on farms, yet their effects on certain crop pests remain understudied. We evaluated whether wildflower plantings adjacent to highbush blueberry (Vaccinium corymbosum L.) fields increased natural enemy abundances and reduced Drosophila suzukii populations compared to fields without this practice. In 2019 and 2020, across 12 farms in Michigan representing 3 management types (conventional management without wildflower plantings, conventional with wildflower plantings, or no chemical pest management), we quantified natural enemies, monitored adult D. suzukii abundance and fruit infestation, and measured removal of D. suzukii pupae. Unsprayed fields supported the highest natural enemy abundance and pupal removal but also had the highest D. suzukii abundance. There was some limited evidence for wildflower plantings increasing natural enemies, such as post-harvest, but overall, there was no significant difference between conventionally managed sites with and without wildflower plantings, and no impact on D. suzukii pupal removal. Additionally, wildflower plantings increased D. suzukii adult abundances post-harvest and in the wildflower plantings compared to mown field margins. Fruit infestation generally remained low in conventionally managed fields irrespective of wildflower plantings. Together, these results suggest that wildflower plantings only provide limited benefits for natural enemies and do not aid in D. suzukii control. Though typically established for pollinators, understanding how habitat enhancements impact particular pests of concern is essential for designing strategies tailored to specific production systems.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149148308","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}

Rhaphidophoridae (cave crickets) are moisture-dependent, ground-dwelling orthopterans associated with caves, rock crevices, and forest-floor refuges. Here, we used occupancy models that account for imperfect detection to examine how habitat structure and elevation influence detection and occupancy probabilities of Rhaphidophoridae across 75 sites, each measuring 1 hectare, in Hidalgo, Mexico. Rhaphidophoridae were present in 33 of 75 sites. The best supported model indicated that detection probability increased with forest-associated habitat structure (tree and shrub cover, deep leaf litter, refuge availability, and low disturbance), whereas occupancy probability increased with elevation. Herbaceous cover did not predict occupancy but was negatively associated with detection. These findings suggest that broad environmental gradients constrain occurrence, whereas detectability is associated with forest structure and lower human disturbance.

To better understand A. glabripennis oviposition and early larval survival, we infested A. rubrum in a common garden environment. We conducted daily observations and destructively harvested these trees to analyze oviposition pit occupation, egg viability, and early larval survival, and compared patterns of oviposition success and survival with field-collected material from naturally infested host trees in the surrounding environment. Oviposition pits on field-collected material were also examined to explore potential links between host tree characteristics and A. glabripennis oviposition success. Our results support previous findings that fecundity is highly variable among individuals, that A. glabripennis oviposition pits were most commonly observed on host material with intermediate sized diameters (6 to 15 cm) and textured bark, and oviposition pits were often chewed without depositing an egg. Oviposition pit occupation, egg viability, and early larval survival were significantly lower on host trees in the common garden environment relative to naturally infested field material.
