Abstract

The sea-swallow 650 C plane carried with a set of HY-1model wind-power spraying machine could spray PEM , a new kind of pesticide which means the pine trees could be exempted from mortality , smoothly on pine forest by means of aerial ultra-low-volume spray , 3.00 ～ 3.75 Lhm-2 (v PEM ∶vwater =1∶2).The adults of Monochamus alternatus could be effectively killed by PEM, by the both way of stomach poison and contact kill.The rate of contact kill to the adults reached 100 %.The rate of stomach poison to feeding adults reached 100 %, with pine branches after 17 days spraying PEM .The absolute mortality rate of pine trees in the pine forest infected by the pine wilt disease , decreased by 37.7 %, comparing with that pine forest without praying PEM .The relative mortality rate of pine trees decrease by 153 %.The best spray dates were in the mid-June , during which the absolute mortality rate of pine trees decreased by 64.0 %.
