摘要：

本文研究了奥绿一号，阿维菌素，Bt3种生物农药对秋甘蓝田节肢动物的影响。结果表明，3种供试生物农药对秋甘蓝主要害虫斜纹夜蛾均有明显的控制效果。3种供试生物农药对秋甘蓝田节肢动物群落的物种丰富度均有一定的短期影响。阿维菌素和Bt对群落多样性有一定影响。奥绿一号可明显提高群落的均匀度，对群落多样性无明显影响，是3种供试生物农药中防治秋甘蓝害虫最优的药剂品种。

Abstract:

The effects of three kinds of bio-insecticides, Aolu No.1, Abamectin and Bt on arthropod community in autumn cabbage fields were studied in this paper. The results showed that each of the three tested bio-insecticides had evident control effects on the major insect pest, Prodenia litura in autumn cabbage fields. Each of the three tested bio-insecticides had some short period effects on species richmmunity diversity. It was the best bio-insecticide in the three tested bio-insecticides for the control of insect pests in autumn caness of arthropod community in autumn cabbage field. Abamectin and Bt had some effects on the community diversities. Aolu No.1 increased evidently the community evenness and had no evident effects on the cobbage fields.
