黄刺蛾Cnidocampa flallescens(Watker)是亚洲的主要森林害虫之一,分布在我国多达21个省(区)。为害木本植物多达34种以上。几年前,在我省的双辽、梨树曾大量发生,虫口高达500—600头/株。1979年—1984年,原来大量发生黄刺蛾为害的林分,由于黄刺蛾NPV的流行,使虫口显著下降。为此,笔者在林间进行了流行致病情况调查,并应用染病毒的土壤、树皮、树叶进行了防治黄刺蛾的试验。现将情况整理如下。 Cnidocampa flallescens (Watker) is one of the major forest pests in Asia and is distributed in up to 21 provinces (regions) in China. Damage to woody plants up to 34 or more. A few years ago, Shuangliao in our province, pear tree has occurred in large numbers, insect population up to 500-600 heads / strain. From 1979 to 1984, a large number of the original boreal moth damage occurred due to the prevalence of Trichoplusia NPV, the insect population decreased significantly. To this end, I conducted a survey of the prevalence of disease in the forest, and the application of the virus-infected soil, bark, leaves of yellow thorn moth test. The situation is now organized as follows.
