Abstract: Several factors influencing the trapping efficiency of the traps on Carposina niponensis were studied in this paper. The results showed that the sex pheromone from the zhongjiesifang company had higher trapping efficiency than the other. The trapping efficiency was significantly different in three types of traps, and the Wing trap was more efficient to be used in monitoring the emergence and population of Carposina niponensis. The best trapping radius was 20-25 m at which the traps showed higher efficiency than that with 15 m or 30 m. The trapping efficiency was obviously impacted by the vegetation coverage, and the effect of traps was easy to be played in the areas of open forest canopy without low shrub.

In this study, several factors influencing the trapping efficiency of the traps on Carposina niponensis were studied. The results demonstrated the sex pheromone from the zhongjiesifang company achieved higher trapping efficiency than the other. Significant trapping efficiency gaps could be witnessed among three types of traps while the Wing trap was with higher monitoring efficiency. The best trapping radius was around 20 to 25 m, at which the trapping efficiency was much higher than that at 15 m or 30 m. The trapping efficiency was prone to be impacted by the vegetation coverage and the traps worked better in the areas of open forest canopy without low shrub.
