通过室内外试验评价了植物保护剂保卫德(BIOACT-T35)对黄曲条跳甲Phyllotreta striolata(F.)种群的控制作用。结果表明,其控制作用主要表现在对成虫的显著忌避和拒食作用。10.00 ml/L的忌避作用为91.42％,选择性和非选择性拒食率分别为93.54％和85.79％,种群趋势指数(I值)由对照的3.8680降为0.3676,干扰作用控制指数(IIPC)为0.0950。采用状态空间分析法的模拟结果表明,其控制作用表现在种群发展初期对成虫的忌避作用。
The control effect of the plant protection agent BIOACT-T35 on the Phyllotreta striolata (F.) Population was evaluated by laboratory tests. The results showed that its control effect mainly manifested in the significant avoidance and antifeedant effect on adults. The repellent effect of 10.00 ml / L was 91.42%, and the rates of selective and non-selective antifeedant were 93.54% and 85.79% respectively. The population trend index (I value) decreased from 3.8680 to 0.3676 and the IIPC was 0.0950. The results of the simulation using state space analysis show that its controlling effect is to avoid the adult in the initial stage of population development.
