| 摘 要： | 本文应用昆虫种群生命表,根据干扰作用控制指数,评价不同杀虫剂及不同施药方法对三化螟种群数量的控制作用.结果表明:杀虫双喷雾防治效果最好,其次是喹硫磷,灭幼脲-1效果较差.同时,应用早稻三化螟连续世代种群生命表方法评价了杀虫脒根区施药和喷雾时对三化螟防治效果,认为根区施药对三化螟种群数量有明显的控制作用.

| Abstract: | Based on life table and the interference iodex of population control,the effects of the different insecticides aod the different applications of Insecticides were evaluated in this paper. The effect of Dimehypo on the population of the paddy borer was the best,and Quinaphos was better than Dimilin- I.Tbe effects of different applications of Chlorodimeform was evaluated by the successive life table. The results showed that root-zone application was much belter than the spraying. |
