五十年代初,国外报导了菜青虫Peris rapae发生颗粒体病毒病。此后不少工作者以引入种群、诱导流行病或喷雾防治等方法,用此种病毒防治菜青虫,均获得良好结果。我国1972年在广州发现了菜青虫颗粒体病毒,近年又相继在各地发现。我们于1978年春季开始进行颗粒体病毒防治菜青虫的试验,现报导部分结果。 In the early 1950s, foreign reports of cabbage worm Peris rapae granulosis virus disease. Since then, many workers have introduced good results by introducing populations, inducing pandemic or spray prevention and control methods and using such viruses to control Pieris rapae. In 1972, we found Pieris rapae virus in Guangzhou. In recent years, it has been found around the world. We started the test of granulosis virus against Pieris rapa on the spring of 1978, and we report some results.
