摘　　要：甘蔗异背长蝽已发展为益阳市甘蔗主要害虫。通过观察,对其形态特征进行描述,并明确该虫在当地1a发生2代。以成虫越冬。越冬代成虫和第一代成虫分别于4月上、中旬和6月底至7月上旬各形成1次成虫产卵高峰。根据研究实践,提出了其发生影响因素和防治方法。Cavelerius saccharivorus has become a major pest in sugarcane in Yiyang city. Its morphological character was described by observation. It was found out that Cavelerius saccharivorus has two generations in a year in Yiyang city. This pest hibernated by adults; There was only one egg peak for the overwintering generation during early and middle April and another egg peak for the first generation from the end of June to early July. Factors affecting the occurrence of Cavelerius saccharivorus and the control measures were suggested according to the research.
