Abstract

AbstractTo monitor insect diversity and community changes, it is necessary to select traps with a high sampling efficiency. We examined the effects of a flight interception window on a small yellow pan trap (flight interception pan; FIP). Our results showed that fewer Hymenoptera individuals were captured by the FIP than by the non‐FIP (NFIP) traps. Fewer Aculeata, Diptera and Hemiptera individuals were captured by the FIP than by the NFIP traps, whereas more Coleoptera individuals were captured by the FIP than by the NFIP traps. The flight interception window did not affect the Aculeata species composition. Considering the labor involved in attaching windows and the reduced ease of trap transport and setting, the NFIP traps are better for sampling Hymenoptera, Diptera and Hemiptera, whereas the FIP traps are better for sampling Coleoptera.
