摘　　要：直升机喷洒噻虫啉防控松墨天牛,采用镁化玻片、塑料薄膜及人工悬挂诱捕器,进行喷洒后的综合评价。结果表明:林冠层雾滴的平均直径为(91.6±2.86)μm,雾滴数量平均为(14.20±2.31)个/cm2,多于林下层,随着林间郁闭度的增大,雾滴直径和数量在减少。喷药后,诱捕器的诱捕数量急速降低,松墨天牛虫口基数下降较大。通过几种监测效果显示,飞机喷洒噻虫啉防治松墨天牛的效果可行。广东河源飞机喷洒噻虫啉防控松墨天牛,天气晴朗,并未偶遇降雨,其对松墨天牛具有较好的防控效果。Thiaeloprid was used for controlling Monochamus alternatus with the helicopters. Magnesium slide, plastic membrane and traps were continued to evaluate control effect. The results showed that the average diameter and number of the droplets could reach 91.6±2.86μm and 14.20±2.31 （cm^2）. With the increase of canopy density, the diameter and number of droplets decreased. After spraying,the trap number of traps decreased rapidly, and the population of M. ahematus decreased greatly. The results detected that it is feasible to control of M. ahernatus by aerial spraying.
