摘　　要：研究了4种寄主植物对舞毒蛾生长发育的影响,结果表明:①舞毒蛾1龄幼虫在山东地区4、5月份对西府海棠、黄栌及垂柳危害严重,对华山松几乎无危害;②舞毒蛾幼虫在上述3种危害严重的寄主植物上均可完成发育,1~3龄时西府海棠为最佳寄主植物,4~6龄垂柳为最佳寄主植物;③寄主植物影响了舞毒蛾幼虫的生长发育历期、体重及头宽,不同寄主植物饲喂下,同龄期体重较小的幼虫头宽也较小;④舞毒蛾幼虫各龄期头宽在组内和组间均重叠较小,同时发生时可用于分龄;而体重重叠区域较大,不适于分龄。The effects of four host plants on the growth and development of Lymantria dispar were studied in this paper.the results were as follows:①The first instar larvae of Lymantria dispar do serious harm to Malus micromalus,Cotinus coggygria and Salix babylonica,weeping willow in April and May in Shandong province,but little harm to Pinus armandii;②Lymantria dispar larvae can complete their development on the above three kinds of host plants with serious damage.Malus micromalus is the best host plant from 1st to 3rd instar,and Salix babylonica is the best host plant from 4th to 6th instar;③The host plants affected the developmental duration,body weight and head width of Lymantria dispar larvae.Under different host plants,the head width of the larvae with smaller body weight in the same age was also smaller;④The overlap of head widths at each instar of Lymantria dispar larvae was small within and between groups,and it could be used for instar differentiation when occurring simultaneously.However,the overlapping area of body weight indicators was large,and it was not suitable for age division.
