Evaluating the efficacy of tagging adhesives for insect tracking
Agricultural and Forest Entomology, EarlyView.Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.
