Interpretive Summary: Thrips are important pests attacking a wide variety of plants including cotton. We have improved our CC traps to catch more thrips for detection and monitoring thrips populations. Results suggest that placing a 1-cm2 Vapona cube increased the CC trap catches by 6X.

Technical Abstract: The fact that different thrips species are attracted to different shades of blue in the field is well documented. This was verified for western flower thrips (WFT), Frankliniella occidentalis (Pergande), in a cotton field in our studies with different shades of blue sticky card traps. Continuing studies are being conducted to improve the efficacy of CC traps for detecting and monitoring thrips populations. Addition of Hot Shot' No-Pest Strip as a killing agent in the traps increased the WFT catches compared with standard CC traps without the killing agent. The increased catches are attributed to increased mortality and retention of thrips that entered the trap as opposed to increased attractiveness.
