摘要
以长白山地区落叶松毛虫为研究对象,对其不同防治技术及效果进行了研究。结果表明:人工采摘卵和蛹可有效防治落叶松毛虫的发生,但在虫口密度较低时则不适于落叶松毛虫的防治;黑光灯和频振灯均能有效地控制落叶松毛虫幼虫虫口密度,降低其危害程度;化学药剂防治中以利用1.8%阿维菌素乳油3 500倍液可达到最佳防治效果,其平均死亡率达92.23%。
The artificial picking of eggs and pupae can effectively prevent the occurrence of Dendrolimussuperans , but it is not suitable for the control of Dendrolimus superans when the density of insect population is low. Both the black light lamp and the frequency vibration lamp can effectively control the density of the larvae of Dendrotimus superans , reduce the degree of damage, and obtain optimal control effects. Using 1.8% avermectin EC 3 500 times solution to control Dendrolimus superans can achieve the optimal control effect, the average mortality rate is 92.23%.
