摘　　要：观察了丝棉木金星尺蛾Abraxas suspecta Warren的取食范围、生物学特性、发生规律及第1代幼虫的寄生天敌。结果表明:该虫仅取食大叶黄杨及其变种,1 a发生4代,以老熟幼虫入土化蛹越冬。第1代幼虫为害最重,幼虫寄生率也最高,其余各代仅零星发生。提出了综合防治措施。The feeding, bionomics, occurrence regularity and parasites on the larva of the first generation of Abraxas suspecta Warren were observed. The result indicated Abraxas suspecta only fed on Euonymus japonicus and its variants. It had 4 generations a year and overwintered as pupa. The larva of the first generation caused most serious damage and the parasitization on it was the highest. Integrated control measures were suggested.
