利用病毒治虫,是一项很有发展前途的生物治虫措施。为了探讨松毛虫病毒对鳞翅目中苹果天社蛾、麻栎天社蛾、榆天社蛾、尺蠖等四种害虫的防治效果,一九七七年我们把新太县土门林场感染病毒而死亡的松毛虫带回捣烂,分别加水五十倍、一百倍、二百倍成三种浓度的死虫液进行了防治试验。试验结果:苹果天社蛾死亡百分之九十四点八至百分之百;麻栎天社蛾死亡百分之八十二至百分之九十七;榆天社蛾死亡百分之九十
The use of virus pest control is a very promising biological pest control measures. In order to investigate the control effect of the pine caterpillar virus on four kinds of pests such as Apple Tree Moss, Leech Tissue, Ulmus, Scylla, etc. in Lepidoptera, in 1977 we infected the Tumen Forest Farm in Xintai County The death of the caterpillars brought back smashed, respectively, water fifty times, one hundred times, two hundred times into three concentrations of insecticide for prevention and control tests. Test results: Death of apple-day moths by 94.8% to 100%; death of Oakland moths by 82% -97%; death of Ulmusteum moth by 90%
