【摘要】 <正> 竹斑蛾(Artona funeralis Bulter)是竹林害虫,广泛分布于我国各竹林产区,大发生时给竹林造成相当大的损害。1979年6月,我们在广州观察到竹斑蛾幼虫在自然情况下常患病死亡。将病死幼虫采回室内,将其脓液涂片,经氨基黑染色及什维佐娃法染色,在光学显微镜下观察,颗粒体分别呈蓝黑和淡红色。初步确定其病原体为颗粒体病毒后,再从野外非病区采回健康幼虫,经感染试验,病征观察、光学显微镜及电子显微镜观察,确证其病原体为颗粒体病毒。1981年,我们又作了室内毒力试验,证明此种颗粒体病毒有更多还原

【Abstract】 This paper reports the results of studies on the granulosis of the zygaenid, Artona funeraIis Buher. The capsules are oval in shape, measured about 240×340 nm. The virions are rod-shaped, about 250 nm in length and 50 nm in diameter. In general, there is only one virus particle in each capsule. Our bioassay showed that the susceptibility of the larvae to the granulosis virus varied with the dosage. The higher the dose of virus, the greater its virulence to the larvae. The virus did not infect the larvae of Bombyx mori (L.).更多还原
