Understanding how these multiple effects unfold is especially important in applied systems where parasitoids play a role in biological control. In lab-based experiments, we manipulated parasitism in striped cucumber beetles, Acalymma vittatum (Coleoptera: Chrysomelidae), a major pest of cucurbits in North America, using Celatoria setosa (Diptera: Tachinidae) to assess how parasitism affected multiple components of male and female fitness, including survival, herbivory, oviposition, and reproductive signaling through the emission of vittatalactone, a male-specific aggregation pheromone. In follow-up experiments, we investigated the potential non-consumptive effects of parasitoids on these metrics by exposing beetles to arenas with or without parasitoids. Parasitized female beetles experienced a 4-fold increase in mortality, consumed 49.6% less leaf tissue, and were less likely to oviposit eggs compared to non-parasitized control females. In addition, parasitized males in small groups emitted 52.5% less vittatalactone than non-parasitized control males. Lastly, we found some evidence of non-consumptive effects of parasitoids in which individual females and groups of males, exposure to parasitoids resulted in reduced foliar damage.

Important measurements of reproduction include individual female egg load and realized fecundity, which can be affected by insect longevity and host quality. Aster leafhoppers (Macrosteles quadrilineatus Forbes) are an important pest in Western Canada and the upper Midwest of the United States, yet little is known about factors influencing their fecundity, and thus, population dynamics. To evaluate age-specific changes in fecundity, newly emerged pairs of aster leafhoppers were caged onto plants, and egg and nymph numbers were determined on a weekly basis until females died. Moreover, water deficit can affect amino acid concentrations in phloem sap, and in turn, affect plant attractiveness and suitability for insect herbivores. To examine the relationship between water deficit and reproductive potential, aster leafhoppers were reared on unstressed and water-stressed barley plants until adult emergence. Pairs with all possible combinations of leafhoppers from each water stress condition were made and allowed to reproduce. Amino acid concentrations were quantified in unstressed and water-stressed barley plants. Aster leafhoppers produced eggs throughout their adult stage, with numbers decreasing as individuals got older. Females reared on water-stressed plants had fewer eggs following adult emergence. Following mating, females that had been reared on unstressed plants had a similar egg load to those that had been reared on water-stressed plants.

We found that single Sugargate diets supported spotted lanternfly development only to the fourth-instar stage. The development time was consistent across diet treatments, but reproduction varied significantly. Spotted lanternfly fed exclusively on grapevines had limited reproductive capability, with only 2 out of 5 females in the Chardonnay treatment laying a single egg mass each, averaging 13 eggs. While spotted lanternflies fed on mixed diets or single tree of heaven laid an average of 2.53 egg masses and 89.7 eggs per female.

Trapping methods were used to examine arthropod communities under 5 crop planting schemes: tobacco monoculture (CK1), soybean monoculture (CK2), soybean ridge and furrow intercropping (T1), soybean single-sided ridge intercropping (T2), and strip intercropping with alternate soybean and tobacco furrows (T3).

Arthropod community composition was stable among the planting schemes, but notable variation was observed among tobacco growth stages. Although intercropping schemes did not significantly impact arthropod density and diversity, these metrics were lower during the seedling stage compared with other growth stages. The densities of herbivores and detritivores under CK2 were significantly higher than those observed under the other planting schemes. Predator and omnivore densities were not affected by the intercropping scheme. Total phosphorus content and soil compaction were critical soil properties that influenced arthropod communities, suggesting that these variables play a crucial role in shaping the trophic structure of the community under intercropping regimes.

This study aims to understand the effects of land use on the pollinator community by describing bee abundance, species richness and community composition in perennial conservation grasslands and adjacent annual row crops located in west central Nebraska. In 2022 and 2023, we collected and identified bees via sticky traps at 4 locations (center and edge of adjacent grasslands and crop fields) at 6 replicated sites. We collected 1,768 specimens from sticky traps, resulting in 70 species within 28 genera. Halictidae accounted for 84% of the specimens collected. Bee abundance was influenced by the simple effects of land use (grassland vs. crops), edge adjacency, and the month and year of collection. Differences in bee abundance within a collection date were found mostly in early 2022 (May and June) and late 2023 (September), when the crop center location was generally the lowest, with some evidence for spillover of bees from the grassland into the crop edge during the early summer months. Bee species richness was affected only by month and was not significantly different by land use and edge adjacency. Bee community composition overlapped across the 4 locations, although there were significant dissimilarities between crop fields and grasslands. Surveys of the plant community revealed very low abundance of blooming stems and plant taxonomic richness at crop locations for all sampling periods, while grassland locations were comparatively high and varied over time. Plant communities showed no overlap between crop field and grassland locations. Overall, we found that conservation grasslands, while not seeded specifically with pollinator-attractive forbs, provide diverse resources to support wild bee communities in west central Nebraska; crop edges may also provide non-plant resources such as nesting sites and irrigation water. Going forward, better understanding pollinator species composition and resource utilization relative to land use characteristics and drought conditions will allow for better tailoring of conservation efforts and management strategies in Nebraska and across the larger region.</p>","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"632-643"},"PeriodicalIF":1.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12199155/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143997594","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}
