茶蚕颗粒体病毒Andra ca bipunctata Granulosis Virus(简称AbGV)系1980年10月从舒城县晓天区红畈生产队茶园的自然死亡茶蚕虫尸分离获得。经研究鉴定,该病毒为我国首次发现。据国内外资料报道,核多角体病毒及颗粒体病毒对宿主昆虫的致病力不仅与毒株的差异有关,而且与宿主的虫龄、虫态及外界环境因子的影响都有密切的关系。为了探明茶蚕颗粒体病毒对不同虫龄的感染效果和某些物理化学因子对病毒感染力的影响程度,为该病毒制剂生产和防治应用提供依据,我们对该病毒的感染浓度、虫龄,以及温度、阳光、紫外线等各种因子的影响进行了探讨。现将试验过程和结果报道如下:
Andra ca bipunctata Granulosis Virus (abbreviated as AbGV) was isolated from the natural death of tea planthoppers in the tea plantation of Hongtao Production Team in Xiaotian District, Shucheng County in October 1980. The study identified that the virus was first discovered in China. According to domestic and foreign data reported, the virulence of NPV and PMV on host insects is not only related to the differences in strains, but also closely related to host’s worm age, insect status and external environmental factors. In order to find out the effect of different infection ages and some physicochemical factors on the virulence of tea worm granulovirus, we provide the basis for the production and application of the virus preparation. , As well as the temperature, sunlight, UV and other factors were discussed. Now the test process and results are reported as follows:
