通过使用低于杨毒蛾 Stilpnotia candida幼虫期灭幼脲 号最佳用药量 (450 g/hm2 )的 5组防治试验 ,得出灭幼脲防治对杨毒蛾其它虫态延续作用显著 ,防治用药 1 50 g/hm2以上 ,杨毒蛾一个世代内总杀虫率可达 96%以上。
Through the use of 5 groups of prevention and control tests which were lower than the optimum dose (450 g / hm2) of the insecticides in the larva of Stilpnotia candida, the results showed that the control of diflubenzuron was significant to the growth of other insects, g / hm2 or more, the total generation insecticidal rate of up to 96% of the genus Thunbergii.
