摘　　要：分别应用不同杀虫剂和昆虫病原线虫Steinernemafeltiae(A24 品系) 对桑皱鞘叶甲Abirusfortunei(Baly)成虫和幼虫进行了田间防治试验,提出桑皱鞘叶甲综合防治措施,即首先在9 ～10 月份桑皱鞘叶甲幼虫进入越冬之前,结合桑园田间管理,清除田间杂草,然后在桑园开沟,按45 ～75 万条线虫/m2 的剂量施用S.feltiae线虫,桑皱鞘叶甲幼虫的防治效果可达88 % 以上,进而减少了翌年其成虫出土数量。在成虫出土始盛期,用甲胺磷或敌敌畏毒土撒施于桑园土面及桑株嫩梢叶上,可较好地控制该虫的为害;如果错过此时施药的桑园,可在成虫出土高峰期用敌敌畏水溶液喷雾。Insecticides and the entomopathogenic nematode, Steinernema feltiae (A24 strain) were evaluated for its potential to control the beetle's adults and larvae in the soil. In September-October, before the beetle's larvae hibernated in the soil, the nematodes were applied into furrows at the rates of 45～75 nematodes/cm 2 after weeds were eradicated from mulberry fields, they produced the mortality ranged from 88.17% to 96.21%, then resulted in 46.2%～86.7% reduction in adult of the beetle emergence. After emergence of the beetle adults, application of insecticides, methamidophos or dichlorvos emulsifiable concentrate, with fine earth, spreading on the mulberry field and branches of mulberry trees, or spraying dichlorvos or dimethoate solution at the beetle adults, resulted in 80.33～97.53 per cent reduction in adult of the beetle.
