为明确高粱田中高粱蚜[Melanaphis sacchari(Zehntner)]捕食性天敌昆虫的群落结构，对高粱蚜捕食性天敌昆虫的种类及数量进行了调查。结果发现：哈尔滨高粱蚜捕食性天敌昆虫共11种，隶属4目5科，主要优势种为龟纹瓢虫( Propylea japonica)、异色瓢虫( Harmonia axyridis)、中华草蛉( Chrysopa sinica)，是高粱蚜发生期的主要控制因素，物种均匀度、丰富度、多样性指数均表现为增加趋势，物种优势度、优势集中性均表现为降低趋势。

To clear the community characteristics of predators insects Melanaphis sacchari( Zehntner) in Sorghum field,the type and quantity of Melanaphis sacchari ( Zehntner ) predators insect were investigated. The research show that the predators insects include 11 species in 4 orders and 5 families. Propylea japonica, Harmonia axyridis,Chrysopa sinica were dominant species,and the main controlling factors. Diversity,evenness,richness, species number, and individual number were gradually increasing. The numbers of dominance and dominant concentration were gradually decreasing.
