为了寻找诱杀小菜蛾的最佳诱捕器与诱芯组合，试验比较了4种诱捕器和2种诱芯的诱蛾效果。结果表明，诱捕器诱蛾效果差异显著(P<0.05)，诱蛾数量为屋脊型诱捕器>漏斗型诱捕器>三角型诱捕器>干式圆柱型诱捕器。诱芯的诱蛾效果受诱捕器的影响，屋脊型诱捕器中，2种诱芯诱蛾效果无显著差异(P>0.05)，而其他诱捕器中，天然橡胶塞诱芯诱蛾效果显著优于塑料毛细管型诱芯(P<0.05)。综合来看，屋脊型诱捕器配合天然橡胶塞诱芯或塑料毛细管型诱芯、漏斗型诱捕器配合天然橡胶塞诱芯这3种组合的诱蛾效果最佳，适用于小菜蛾防治。

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.
