病毒是害虫种群数量自然调节的一个重要因子。近年来,我国利用病毒防治森林害虫的研究工作有了一些进展,据不完全统计,我国已采集分离到70余种森林害虫病毒,其中7种为质型多角体病毒(CPV)。1983年我们在河北省进行昆虫病毒资源调查时,采集分离到柳毒蛾(Leucoma Salicis)和盗毒蛾(PorthesiaSimilis)CPV,这两种病毒国内未见正式报道,现简述如下。1.柳毒蛾质型多角体病毒1983年5-6月分别在河北的易县、望都、承德、宜化、保定等地采集到柳毒蛾的病死虫,
Viruses are an important factor in the natural regulation of the population of pests. In recent years, some progresses have been made in the research on the prevention and control of forest pests by viruses in our country. According to incomplete statistics, more than 70 species of forest pests have been collected and isolated in our country, of which 7 are polyhedrosis virus (CPV). In 1983, when we surveyed the insect virus resources in Hebei Province, we collected the CPVs isolated from Leucoma Salicis and PorthesiaSimilis. The two viruses were not officially reported in China and are summarized as follows. 1. Liu poisonous moth type polyhedrosis virus 1983 May to June respectively in Yixian, Wangdu, Chengde, Yihua, Baoding and other places to collect the dead worm of venom,
