栗黄枯叶蛾(Trabala vishnou Lef-ebure)是一种园林树木害虫,为害大叶紫薇、枫香、栎及相思等。1984年10月初,在本所标本园的大叶紫薇树上采到该幼虫。在室内置于养虫盅(10×15厘米)饲养,幼虫全部死亡。死虫以尾足勾住枝叶倒吊,体内组织液化下垂,稍触即破烂,流出浓液。浓液无臭,镜检发现大量的多角体。伊红染色多角体呈粉红色。扫描电镜观察,多角体有些呈不规则形,大部分呈六角形的十四面体(由两个六边形和十二个梯形的面组成),大小为0.6～3.0微米(见封三图1)。超薄切片透镜观察,多角体内包埋许多长杆状的病毒束,病毒束两端钝圆,内有单粒、双粒及叁粒病毒 Trabala vishnou Lef-ebure is a garden tree pest, which damages Lagerstroemia speciosa, Liquidambar formosum, oak and Acacia. In early October 1984, the larva was collected on the big-leaved crape myrtle in our specimen garden. In the room placed in the pitcher (10 × 15 cm) feeding, larvae all died. Dead insects to the tail foot hook foliage upside down, liquefied tissue drooping, touch that is broken, out of the concentrate. Drizzle odorless, microscopic examination revealed a large number of polyhedra. Eosin staining polyhedra is pink. Scanning electron microscopy, some of polyhedron irregular shape, most of hexagonal tetrahedron (composed of two hexagonal and twelve trapezoidal surface), the size of 0.6 to 3.0 microns 1). Ultra-thin sectioned lens observation, polygonal body embedded in many long rod-shaped virus bundles, both ends of the virus bundle blunt round, there are single, double and triple virus
