1980年中林院从日本引进赤松毛虫质型多角体病毒(JDS—CPV),曾先后在广东、河北、浙江等省用于马尾松毛虫的增殖和大面积防治试验,取得了良好的效果。为扩大JDS—CPV的应用范围,我们于1984和1986年采用塑料围栏集虫感染增殖方法,在文山松毛虫上生产JDS—CPV获得成功。84年7—8月,在红旗林场进行50亩大龄虫的防治试验,防治效果也十分显著。现将试验结果整理如下。
In 1980, Zhonglin Academy introduced the Dendrolimus punctatus polyhedrosis virus (JDS-CPV) from Japan. It was used in the proliferation and large-area prevention and control of Dendrolimus punctatus successively in Guangdong, Hebei and Zhejiang provinces and achieved good results. To expand the scope of application of JDS-CPV, we successfully used plastic fence collection in 1984 and 1986 to produce JDS-CPV on Pinus densiflora. From July to August in 1984, prevention and control of 50-year-old insects in Hongqi Forest Farm was carried out, and the control effect was also remarkable. The test results are summarized below.
