危害紫藤的新害虫——紫藤阿西克象甲

Report of Acicnemis palliata damaging Wisteria sinensis in China

2018年4月,在紫藤Wisteria sinensis树上发现一种钻蛀性害虫,经专家鉴定为紫藤阿西克象甲Acicnemis palliata Pascoe(Coleoptera:Curculionidae),其幼虫在寄主树干内取食危害,严重影响紫藤健康生长,威胁到紫藤的种植、栽培和景观效应。文献记载该虫在中国、日本、韩国均有分布,但在国内尚未见相关研究报道。经过大量观测研究记录,报道其分类地位、形态特征、生物学特性、危害性状和防治方法,以期为紫藤阿西克象甲的识别与防治提供参考。

A borer pest was found on Wisteria sinensis in April 2018,and was identified as Acicnemis palliata Pascoe(Coleoptera:Curculionidae).The larvae fed on the trunk of the host plants,which seriously affects the healthy growth of W.sinensis and threatened the planting,cultivation and landscape effects of W.sinensis.It was reported that A.palliata was distributed in China,Japan and South Korea,but had not been reported in China.In this paper,we reported its morphological characteristics,biology,damage characters as well as control methods based on laboratory and field observations.
