松墨天牛林间防治试验

Control Trail of Monochamus alternatus (Hope) in the Forest

松墨天牛[Monochamus alternatus(Hope)]是松材线虫病的主要传播媒介,又是马尾松、黑松、雪松、落叶松、云南松等松类植物的重要害虫。为了控制虫灾探讨有效防治技术,特进行噻虫啉、绿僵菌防治松墨天牛的试验。结果表明:应用噻虫啉和绿僵菌无纺布菌条林间防治松墨天牛均有良好的防治效果,从维护物种多样性和森林健康的角度来看,采用绿僵菌无纺布菌条防治松墨天牛具有更好的发展前景。

Monochamus alternatus（Hope） is the major media of pine wilt disease,and are also the main pests of Masson＇s Pine,Pinus thunbergii,Cedrus deodara,larch,Larix olgensis and other conifers.Thiacloprid and Metarhizium were chosen in the experiment to control the insect number and find the control techniques.Results showed that both Thiacloprid and Metarhizium anisopliae had good control effects,of which Metarhizium anisopliae controlled Monochamus alternatus（Hope） than what Thiacloprid did if from the angle of maintaining species diversity and forest health.
