本文报道了樟叶蜂幼虫的一种病毒病。病毒只在寄主中肠组织中细胞核内复制,故称为肠型核多角体病毒病而有别于鳞翅目昆虫中核多角体病毒病。病虫肛门流出粘液,粘液干后,幼虫尾部就粘附在基质上。因此,感病晚期或已死的幼虫其躯体则头部往下而悬垂于枝、叶上。感病初期,幼虫行动呆滞、食欲不振,体色由正常的绿色逐渐变为棕褐色。 多角体在扫描电子显微镜下观察,为五边形或六边形的多角体,大小0.6—1.0μm,在超薄切片中,多角体的晶格为点线型,点间距为50A,病毒粒子杆状,大小为227×71nm。
This article reports a viral disease of the larvae of the camphor bee. The virus is only replicated in the nucleus of the host in the midgut tissue, so it is called the enteric polyhedrosis virus and differs from the lepidopteran insect nuclear polyhedrosis virus. Pests and worms flow out of mucus, mucus dry, larvae tail adhesion to the substrate. Therefore, late stage or dead larvae are the body head down and dangling branches and leaves. Early flu, sluggish lagomorphs, loss of appetite, body color gradually from the normal green to brown. The polyhedron is observed under a scanning electron microscope as a pentagonal or hexagonal polyhedron with a size of 0.6-1.0 μm. In the ultrathin section, the lattice of the polyhedron is a point-line type with a dot spacing of 50 A and the virus particles Rod-shaped, the size of 227 × 71nm.
