暗翅足距小蠹为害新寄主植物李树

Harm of Xylosandrus crassiusculus to the New Host Plant,Prunus salicina

通过野外调查、剖干采集、室内镜检等方法,首次明确暗翅足距小蠹可危害生长健康的李树植株,记述了该害虫的分类地位和地理分布信息,明确了暗翅足距小蠹的鉴别特征,并描述了其在李树上的危害性状和根治方法。此外,提供了足距小蠹属的分种检索表。

This work,based on field investigation,cutting collection and indoor microscopic examination,confirmed for the 1st time that the Asian ambrosia beetle,Xylosandrus crassiusculus(Motschulsky)could attack the robust plums.Then,the classification status and geographic distribution of X.crassiusculus were summarized,and the diagnosis characters of this species were also defined.Also,the harmful characters of the newly discovered host plant plums and the control methods were well described.A key to the known species of Xylosandrus Reitter from China was finally proposed.
