Abstract: In order to find the best combination of sex pheromone traps and lures on Plutella xylotessa L., the trapping efficiency of 4 traps and 2 lures were compared. The results showed that, there were significant difference among 4 traps (P<0.05). The amount of insect trapped were in the order of ridge type trap> funnel type trap> triangle trap> dry cylinder trap, and the two former were much suitable for Plutella xylotessa L. control. The trapping effect of sex pheromone lures was affected by traps. The 2 lures were no significant difference in the ridge type traps(P<0.05), however, plastic capillary lure was significant better than rubber plug in other three traps(P>0.05). These data reveal that three treatments, ridge type trap comminuted with rubber plug or plastic capillary, and funnel type trap comminuted with rubber plug, were the best combination to control Plutella xylostella.
