本研究通过用农药农蒙特(25×10~(-6))和氯氰菊酯(20×10~(-6))处理,采用生命表技术和控制效应来评判农药亚致死剂量对田间小菜蛾和优姬蜂种群动力学的影响。结果表明,农蒙特和氯氰菊酯对优姬蜂种群的控制效应大于对小菜蛾种群的控制效应,寄生在农蒙特处理的小菜蛾幼虫体内的优姬蜂幼虫的死亡率显著地高于氯氰菊酯处理的和对照的,表现出农蒙特对寄生蜂影响的深远性。
In this study, life table techniques and control effects were used to evaluate the effects of sub-lethal doses of pesticides on diamondback moth and diamondback moth (Plutella xylostella) in the field by using pesticides (25 × 10 -6) and cypermethrin (20 × 10 -6) Effect of the population dynamics of Myzus persicae. The results showed that the control effect of Nongmon and cypermethrin on the population of M. gigas was larger than that on P. xylostella population. The mortality of M. gigas larvae parasitized by the agricultural monkeys was significantly higher than that of cypermethrin-treated and In contrast, the far-reaching nature of the effect of the agricultural mononuclear parasitoid was demonstrated.
