Summary: This study used DNA barcoding to reconstruct quantitative three- and four-trophic interaction networks of cavity-nesting wasps, their prey, and natural enemies. The research identified previously unknown predator-prey interactions, including prey species that are known as agricultural and forest pests. The authors found that trap nests, when combined with DNA barcoding, are a valuable tool for monitoring these multi-trophic interactions and for revealing unknown feeding links.
