摘　　要： 应用扩展的均匀设计 ,探讨了不同蔬菜种类、不同小菜蛾卵量基数和不同性诱剂诱盆数量等条件下小菜蛾性诱剂的控制效果。结果表明 ,小菜蛾卵量基数和诱盆数量的变化是影响控制效果的主要因素 ,而蔬菜种类的作用较小 ;同时建立了控制效果与这些因素之间变化的动态模型。通过对该模型的分析和模拟 ,建立了田间不同条件下性诱剂的定量化应用技术。 The control effect of the diamondback Moth, Plutella xylostella L using synthetic sex pheromones in different vegetable varieties, different initial numbers of DBM eggs and different numbers of the attracted pots were studied with the method of expanded even design The results showed that the main factors of control effect were the initial numbers of DBM eggs and the numbers of attracted pots, the effects of vegetable varieties was low The dynamic model of control effect with those factors was built up Thought analyzing and simulating, the quantitative applied technology of synthetic sex pheromones under different factors in vegetable fields was raised
