Studies were conducted to develop thrips traps for detecting and identifying Scirtothrips dorsalis (Hood). Traps were developed in Arizona where Frankliniella occidentalis (Pergande) are established in the field, and they were tested in southern Taiwan where S. dorsalis thrips are found. Addition of a one square centimeter of dichlorvos (Vapona®) pest strip as a killing agent in CC traps increased the catches of western flower thrips 5-fold as compared to standard CC traps. The increased thrips catches are attributed to increased mortality and retention of thrips that entered the traps as opposed to increased attractiveness of the trap. Average CC trap catches in Taiwan were 0.07 S. dorsalis per CC trap per week.
