Interpretive Summary: We investigated sticky card trap configuration and the trap efficacy for western flower thrips (WFT). Results showed that same area of blue or yellow sticky card with different perimeters caught different numbers of WFT. More WFT were caught on longer perimeter traps compared with shorter perimeter.

Technical Abstract: The numbers of Frankliniella occidentalis (WFT) caught on flat surface rectangular blue sticky cards were the highest for 36-cm traps (largest perimeters), followed by 30.2-cm (intermediate perimeters) and 26.8-cm traps (smallest perimeters). Similar to the blue card traps, more WFT (70-80% of the total) were caught on 36-cm yellow traps (No. WFT/trap/wk=174) followed by 30.5-cm yellow traps (No. WFT/trap/wk=102), and 26.8-cm yellow traps (No. WFT/trap/wk=52). More WFT (70-80% of the total) were trapped on the edge areas of all flat surface rectangular blue sticky cards or yellow cards compared with the interiors of the trap surfaces.
