摘　　要：研究大豆不同种植方式对大豆害虫及其天敌种类和数量关系的结果指出：（１）大豆地的大豆害虫及其天敌种类、数量和组成，随早、晚大豆种植方式的不同而不同；（２）清种早（晚）大豆、早大豆间蕃茄、早（晚）大豆间辣椒害虫较多；（３）其种类，早大豆是突眼长蝽，晚大豆是豆荚螟、负蝗和银纹夜蛾较多；（４）大豆害虫天敌，早、晚大豆均以草蛉最多，异色瓢虫第二。The study shows:(1)the sorts, numbers and formation of insects and their predators insoybean are different with the cropping patterns of early and late soybean.(2)There are moreinsects in three cropping patterns,i.e.,“soybenn(early or late soybean) only”,“early soybeanintercropped with tomato”and“early or late soyhean intercropped with kayenne pepper”.(3)The major insect in early soybean is Chanliops fallat scott, and the mayor insects in latesoybean are Etielly zinckenalla,Atractomorpha siyiesis Bolivar,and Argyrogramma agnata(Staudinger).(4)The predators of the insects are mainly Chrysopidae and Leis axyridis(Pallas),and the number of Chrysopidae is larger than that of Leis axyrzdis(Pallas).
