Abstract
Background: Spotted wing drosophila (SWD), Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is a pest of stone and small fruits causing considerable economic losses. Current management strategies rely primarily on calendar‐based spraying, owing to the poor relationship between monitoring data and damage levels, and the lack of success of mass‐trapping tools. The aim of this study was to evaluate different trap models for SWD, with an emphasis on their fly‐retention capacity. To this end, we examined and quantified the added value of two fly‐retaining trap features; tunnel entries to impede escape and an insecticide‐coated inner surface as a killing agent. Results: An insecticide‐coated inner surface resulted in significantly higher trap retention after 24 h in the laboratory (4.9‐ to 7.4‐fold greater, depending on trap type) compared to a noncoated trap. Trapping efficacy was significantly improved in field trials by such a killing agent in the trap (1.2‐ to 4.5‐fold greater). Tunnel entries significantly improved trap retention in the laboratory and field (by 1.5‐fold). Conclusion: The outcomes of this study clearly reveal the substantial impact of the fly‐retention capacity of SWD traps on their overall capture performances. It was demonstrated for the first time that an insecticide‐coated inner surface as a killing agent significantly improves trap efficacy for SWD. This finding can readily be implemented in any trap model to improve monitoring and mass trapping of SWD. Also tunnel entries were shown to have a significant influence on the fly retention and, hence, substantially enhance trapping efficacy.
