Evaluation of metabarcoding-based identifications for monitoring beetle communities

This project evaluates the suitability of both tissue-based and preservative-based DNA metabarcoding approaches for potential use in large-scale forest insect monitoring initiatives, with a focus on beetle communities. To this end, the contents of pitfall (Barber) traps and corresponding cross-window traps were analysed for the presence of Coleoptera species. The performance of three common preservatives was compared in terms of species and DNA preservation, and the optimal time interval for trap replacement was determined.
