Improvement of cc traps for catching frankliniella occidentalis. Southwestern Entomologist Vol 31(3): 201-210. Interpretive Summary: We developed a thrips trap for monitoring western flower thrips in the field. The trap is a modification of CC whitefly trap by 1) the use of blue trap base to attract western flower thrips and 2) addition of a piece of Vapona cube in the trap top as a killing agent that retains the thrips that entered into the trap. Technical Abstract: Variable numbers of western flower thrips (WFT), Frankliniella occidentalis (Pergande), were attracted to sticky cards reflecting different wavelengths of blue color light in a cotton field. The highest numbers were captured on blue sticky cards reflecting 458 nm compared with 446 nm and 444 nm wavelength light reflectance. WFT catches were improved in CC traps by putting pieces of Hot Shot' No-Pest Strips (dichlorvos) in blue base trap tops as killing agents. The increased catches occurred because of higher thrips mortality and retention in traps as opposed to increased trap attractiveness. Catches were higher for the modified commercial dichlorvos dispensers with vertical blue stripe modifications (Blue-D) compared with blue base CC traps with dichlorvos cubes. |
