应用信息化合物防治小蠹虫的研究进展

Advance in Reaearches on Using Semiochemicals to Control Bark Beetles

小蠹虫是世界上重要的森林害虫,常造成森林大面积死亡。小蠹虫多存在于高中山区且其生活隐蔽,利用传统的防治方法很难达到较好的效果。近年来利用化学信息物质防治小蠹虫成为国内外研究的热点。本文简要概述了化学信息物质,特别是寄主次生性物质和小蠹虫信息素对小蠹虫寄主选择行为的影响,以及国内外应用化学信息物质防治小蠹虫的进展。

As one of global forest pests,bark beetles often make lots of trees withered.Bark beetles mostly live in the high and cliffy mountainous areas,so using traditional methods are often difficult to achieve better control results.In recent years,using semiocheicals to control bark beetles has been a hot spot at home and abroad.This paper reviewes the impact of semiochemicals on bark beetles,especially the important role of secondary substances and pheromones,and the present conditions and advances of using semiochemicals to control bark beetles.
