摘　　要： 为科学组建甘蓝田菜青虫的综合治理措施,本研究通过田间试验和系统调查研究了阿维菌素、Bt和‘奥绿一号’3种生物农药对春甘蓝田菜青虫及节肢动物群落的影响。结果表明:这几种生物农药处理对菜青虫种群均有显著的控制作用,可大幅降低春甘蓝田节肢动物群落的总个体数,提高群落的多样性和稳定性。使用阿维菌素和‘奥绿一号’防治甘蓝田菜青虫,可提高甘蓝田节肢动物群落的益害比,有助于保护和加强天敌的自然控制作用。 Based on the field experiments and systematic investigation,the effects of three bioinsecticides,abamectin,Bt and ＇ Aolv No.1 ＇,on the population of Pieris rapae and the arthropod community in spring cabbage fields were studied in this paper in order to constitute the integrated control methods of Pieris rapae scientifically.The results showed that：the three bioinsecticides had evident control effects on population growth of Pieris rapae,were able to reduce the total individuals and raise the diversity and stability of the arthropod community in spring cabbage fields.The use of abamectin and ＇ Aolv No.1 ＇ for the control of Pieris rapae was able to raise the ratio of number of natural enemy to insect pest and helpful to protect and promote the control effects of natural enemies to insect pests in cabbage fields.
