Abstract Context Land use changes have become a major driver of biodiversity loss, impacting natural ecosystems and the species that depend on them. As result, many isolated from their habitats cannot interact with other as they would in ecosystems. Ecological interactions are crucial for functioning stability Objectives Here, we aimed to evaluate effects landscape structure enemy community antagonistic networks consisting enemies solitary trap-nesting bees wasps, at two scales. Methods Trap-nests were installed forest edges Cantareira-Mantiqueira Corridor (CCM), Atlantic Forest biome located São Paulo state, Brazil. Natural was described using richness, abundance (number attacked brood cells), parasitism rate, taxonomic diversity. While describe host-natural network used robustness metric, enemy’s niche overlap, linkage density. Results The is richer when there high connectivity local scale, while heterogeneity increases abundance, diversity, rate. High similarity between species’ trophic niches occurs antagonist dominated by generalist enemies. Conclusions Our study presents one first results about functional communities interactions, highlighting importance its conservation not just insects respond only presence hosts region. specialist networks, both bee wasp hosts, may occur through increased patches landscapes restored fragments.
