Abstract: Several factors influencing the trapping efficiency of the traps on Carposina sasakii were investigated. The sex pheromone from the Zhongjiesifang company trapped more moths than another product. Trap design affected trapping efficiency, the Wing trap was more efficient. The effective trapping radius was 20-25 m, trap catches were significantly higher at that distance than at 15 m or 30 m. And trapping efficiency was also connected with vegetation coverage, trap catches were higher in areas of open forest canopy without low shrub.
