| 摘 要： | 小菜蛾Plutella xylostella(L.)是十字花科蔬菜的一种主要害虫。由于小菜蛾生育期短,世代重叠严重,如何对小菜蛾进行代次划分,是对小菜蛾进行准确预测预报的关键。通过整理2003、2004年2年来的田间观测数据资料,认为对小菜蛾进行代次划分的关键因子是温度,并总结出不同温度下各代发生的天数作为小菜蛾代次划分的主要依据。

| Abstract: | Diamond back moth,Plutella xylostella(L.),is a major pest on cruciferous vegetables.Because its short developmental period,the field populations show severe generation overlap.Suitable generation partition in field populations is of crucial importance for forecast of the pest.We proposed a generation partition scheme for the field populations of P.xylostella based on two years field observations. |
