在实验室用人工饲料饲养了冬初和冬末草场采集的斑点地老虎幼虫。对饲养过程中死亡的幼虫进行了显微镜检查。1983年4月和5月，病幼虫的主要病原被鉴定为核型多角体病和肉芽肿病。观察到两种不同类型的多面体：一种是四角形的，另一种是三角形的。碱释放的病毒粒子呈杆状，大小为80-190倍。四方晶型为320-380 nm，倍数为95-165。三角型为345-385 nm。GV闭塞体呈椭圆形，测量次数。0.2-0.3倍。0.4-0.6µm。GV核衣壳呈轻微弯曲，大小为70~72次。400-405 nm。
The larvae of the spotted cutworm collected from grass fields at the beginning and the end of winter season were reared on an artificial diet in the laboratory. The larvae which died in the course of rearing were microscopically examined. In April and May, 1983, the main causative agents of diseased larvae were identified as nuclear polyhedrosis and granulosis [GV]. Two different types of polyhedra were observed: one was tetragonal and the other was trigonal in shape. Alkaline-liberated virions were rod-shaped and measured 80-190 .times. 320-380 nm in the tetragonal type and 95-165 .times. 345-385 nm in the trigonal type. The occlusion bodies of GV were ellipsoidal and measured .times. 0.2-0.3 .times. 0.4-0.6 .mu.m. Nucleocapsids of GV were slightly curved and measured 70-72 .times. 400-405 nm.
