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 Bamboo leaf moth (Artona funeralis Bulter) is a bamboo forest pests, widely distributed in various bamboo forest areas in China, when the big bamboo forest caused considerable damage. In June 1979, we observed in Guangdong that M. infestans larvae often died of illness under natural conditions. The dead larvae were taken back to the room, the pus smear, the amino black staining and even Vizzo blue staining, observed under a light microscope, the particles were blue and red and pink. After preliminary identification of the pathogen as the granulosis virus, the healthy larvae were recovered from the non-endemic area of ​​the wild. After infection test, symptom observation, light microscope and electron microscope observation, it was confirmed that the pathogen was granulovirus. In 1981, we also made indoor toxicity test to prove that such a granular virus
