Abstract: This paper shows Sea swallow 650C plane carried with a HY-1 model wind power spraying machine can lay um mines(contacted breaking release micro capsules)smoothly on pine forest by means of aerial ultra low volume spray,per 67?hm 2 volume of contacted breaking release microcapsults:water=1∶3 is about 900 mL.The adults of Monochamus alternatus can be effectively killed by microcapsules when the adults ate or stepped on one,which led to decreasing by 38.8% of mortality rate of pine trees in the infected pine forest,compared with that in pine forest C.K.
