摘　　要：该文分析甘薯小象虫发生规律及不同类型田危害程度、不同灌溉方式对其发生的影响,并进行药剂筛选试验。结果表明:甘薯小象虫9～11月发生量最大;甘薯小象虫在旱作区发生较重;灌溉既能提高甘薯产量,同时又可有效控制甘薯小象虫的为害;可使用乐斯本浇灌防治甘薯小象虫。Occurrence regularity of Cylas formicarius Fabricius and the effects of occurrence at different harm degrees of field and different irrigation methods were analysed in the paper.And drug screening tests were conducted.The resulted showed that the peak occurrence period of C.formicarius was from September to December;C.formicarius occurred much more heavily in the upland farming areas;irrigation could not only improve the sweet potato yield but also effectively control C.formicarius;so it was helpful to control C.formicarius by irrigating with Lorben.
