Precaution of an Alien Palm Pest——Palmetto weevil

深红棕榈象[Rhynchophorus cruentatus (Fabricus)]是棕榈植物的重要害虫,主要分布于美国南卡罗莱纳州、佛罗里达州、得克萨斯州。随着我国对外引进植物苗木贸易的频繁交流,该虫通过引进寄主植物携带传入我国的可能性很大。对深红棕榈象的分布、寄主植物、形态特征、生物学特性、危害特征作了简要介绍,并提出了预防与控制建议。

The palmetto weevil,Rhynchophorus cruentatus（Fabricus）,which has been reported from coastal South Carolina through the Florida,and west into coastal Texas,is a very dangerous palm pest.With the frequent trade of plant,it is likely to be invaded into China.For the precaution of an alien palm pest,we reviewed the research on its distribution,host,morphological feature,biology and harmfulness,and the prevention strategy was given in this paper.
