摘　　要：本试验利用直升飞机在林间喷洒8%氯氰菊酯微囊悬浮剂,并采用诱捕器监测松褐天牛和褐梗天牛的虫口密度。结果表明,在喷药后2 d,8%氯氰菊酯微囊悬浮剂对松褐天牛的虫口减退率和防效分别为96%和95.09%,对褐梗天牛的虫口减退率和防效分别为70.97%和67.34%;喷药后连续观察32 d,8%氯氰菊酯微囊悬浮剂对松褐天牛的虫口减退率和防效始终高于90%和86.75%,波动不大,且曲线接近直线,而对褐梗天牛的虫口减退率和防效低于松褐天牛,曲线呈波动状态。说明用直升飞机在林间喷洒8%氯氰菊酯微囊悬浮剂对松褐天牛的防效比对褐梗天牛的速效性强,防效好。In this experiment,helicopters were used to spray 8%Cypermethrin microcapsule CS in the forest,and traps were used to monitor the population density of Monochamus alternatus and Arhopalus rusticus.The results showed that,2 days after spraying,8%Cypermethrin microcapsule CS was 96%and 95.09%for Monochamus alternatus and 70.97%and 67.34%for Arhopalus rusticus.After continuous observation for 32 days after spraying,the reduction rate and control effect of 8%Cypermethrin on monochamus alternatus were higher than 90%and 86.75%,and the curve was close to a straight line,however,the population decline rate and control effect of Arhopalus rusticus were lower than that of Monochamus alternatus.The results showed that spraying 8%cypermethrin microcapsule CS in forest by helicopter had better control effect on Monochamus alternatus than that on Arhopalus rusticus.
