The results showed that the effective period of thread-shaped attractants was longer than that of cup-shaped. There was no difference between different colors of container. The efficiency of attracting male moth during 18:00～22:00 was significantly lower than that in other period in night. In addition, the effect of sleeve-shaped trap was higher than that of water basin.
