Although spotted lanternfly can develop when feeding solely on grapevines, the extent to which different grape cultivars support its survival and reproduction is less clear. We investigated the effect of grapevines and tree of heaven diets on spotted lanternfly survival, development, and reproduction. We fed nymphs and adults on either single or mixed diets of tree of heaven and 4 grapevine cultivars: 'Cabernet Franc' (Vitis vinifera), 'Chardonnay' (V. vinifera), 'Concord' (V. labrusca), and 'Sugargate' (Muscadinia rotundifolia). 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. In conclusion, some single grapevine diets support development to adulthood but reproduction is limited without tree of heaven.

To address this knowledge gap, we conducted a study from April to September 2023, in a karst area to evaluate the impacts of tobacco-soybean intercropping on ground-dwelling arthropods and soil properties. 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). Formicidae were the predominant taxa across all planting schemes, with more shared taxa than unique taxa among the planting schemes. 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":"","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":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
