Trap nests for bees and wasps to analyse trophic interactions in changing environments—A systematic overview and user guide

Trap nests are artificially made nesting resources for solitary cavity‐nesting bees and wasps and allow easy quantification of multiple trophic interactions between bees, wasps, their food objects and natural enemies. We synthesized all trap nest studies available in the ISI Web of Science ™ to provide a comprehensive overview of trap nest research and identify common practical challenges and promising future research directions. Trap nests have...
