近十年来,国际上已有五种昆虫病毒作为商品生产,供应防治害虫,为少用化学农药、减轻环境污染提供了有利条件。这五种病毒都是核多角体病毒,简称“NPV”,是由感染昆虫的细胞核内自己复制的,所含病毒颗粒是嵌入一种多角形的蛋白质模型或内含体中,颗粒含有核酸,由核酸而引发病毒病。 大约有83%的病毒是从鳞翅目昆虫的幼虫分离而得。幼虫吃进有病毒的植物,在胃里溶解几秒钟后
In the past ten years, five kinds of insect viruses have been produced as commodities in the world and pest control has been provided. This has provided favorable conditions for reducing the use of chemical pesticides and alleviating environmental pollution. These five viruses are both nuclear polyhedrosis viruses (NPVs), which are themselves replicated in the nucleus of infected insects and contain virus particles embedded in a polygonal, protein model or inclusion body containing nucleic acids, Virus caused by nucleic acid disease. About 83% of the virus is isolated from larvae of Lepidoptera. The larvae eat the virus-bearing plants and dissolve in the stomach for a few seconds
