摘　　要：通过对接种 ZrNPV 后落叶松绶尺蠖幼虫的各种组织进行光学显微镜和电子显微镜观察、发现落叶松绶尺蠖核型多角体病毒在脂肪体,表皮细胞,中肠细胞,气管基质和血细胞内复制。上述细胞受感染后均出现明显的病理变化,细胞核增大。在电镜下可观察到受感染组织的细胞核内出现病毒粒子和多角体,70～140 h 所有受感染组织核内充满多角体。This paper reports the histological observation of larvae of Zethenia rufescent- aria Motsch.after infection by ZrNPV.Histopathologic study revealed that ZrNPV were multiplied within the nuclear of fat body,epidermis cell,midgut cell,tracheal matrix and blood cell,These cells showed obvious cytopathic effects.The nucleus of infected cells underwent swelled.Under electron microscope,virons and polyhedra of ZrNPV were clearly observed in these nucleus of infected cells. During 70～140h,after infection the nucleus of susceptible tissues were fullfilled with polyhedra.
