摘　　要：应用直升机超低量喷洒DpCPV复合剂对第一代马尾松毛虫进行大面积防治试验,同时对其防治效果进行跟踪调查。结果表明:直升机H125和R44两种机型对DpCPV复合剂喷洒效果良好,第一代马尾松毛虫平均校正虫口减退率为87.51%;同时DpCPV对马尾松毛虫具有持续防控效果,一次防治至少可控制3—4年不成灾。研究结果为今后大规模利用DpCPV复合剂进行马尾松毛虫灾害的预防和控制提供科学依据。The control experiment of the first generation of Dendrolimus punctatus Walker was carried out by spraying DpCPV compound agents in ultra-low volume by helicopter,and the persistence of DpCPV to D.punctatus was investigated in this paper.The results showed that both H125 and R44 helicopters had good spraying effect on DpCPV compound agents,and the average corrected population decline rate of the first generation of D.punctatus was 87.51%.Meanwhile,the DpCPV had a sustained control effect on D.punctatus in the forest,and the control effect could last for at least 3-4 years.These results would provide a scientific basis for the prevention and control of D.punctatus disaster by using DpCPV compound agents on a large scale in the future.
