摘　　要：[目的]探明甘蔗田间昆虫群落结构、各种昆虫在群落中的地位、重要种的消长情况和天敌的抑制作用。[方法]对册亨县不同海拔高度甘蔗田间昆虫群落进行了系统调查。[结果]昆虫种类分别属于12个目24个科,其中以鞘翅目种类最多,其次是半翅目和鳞翅目。害虫优势种主要是甘蔗绵蚜[Ceratovacuna lanigera(Zehntner)];天敌优势种主要有大突肩瓢虫[Synonycha grandis(Thunberg)]、黄斑盘瓢虫(Coelophora saucia Mulsant)和黑方突毛瓢虫[Pseudoscymnus kurohime(Miyatake)]3种。不同海拔的甘蔗田间昆虫群落有差异。[结论]研究结果为甘蔗虫害的综合治理提供了理论依据。[Objective] The aim was to understand insect communities in sugarcane field,status of insects in community,change condition of important species and inhibition of natural enemy. [Method] The insect communities in sugarcane field from different elevation above the sea level in Ceheng County were investigated systematically. [Result] The insects species belonged to 12 orders and 24 families respectively. Among them all,the order Colepptera taked up the most of it,and then came the order Hemiptera and the order Lepidoptera. The dominant species of injurious insect mainly was Ceratovacuna lanigera Zehntner,and the dominant species of natural enemy mainly contained three species which were Synonycha grandis（ Thunberg）,Lemnia saucia and Pseudoscymnus kurohime（ Miyatake）. The insect communities in sugarcane field had the difference due to the various elevation. [Conclusion] The results provide theoretical basis for comprehensive control of insect pests of sugarcane.
