浙江茶园尺蠖新成员——大造桥虫

A New Member of Tea Looper in Zhejiang Tea Plantation——Ascotis selenaria

大造桥虫隶属于鳞翅目尺蛾科,是一种食性多杂的世界性农业害虫。在日本茶园中被列为主要的茶树害虫,在我国绝大多数茶树种植省份均有分布记载,但并不属于我国茶树害虫防治的重点目标,鲜有在茶树上的详细资料报道。近些年来,在江南茶区该虫呈现区域性、间隔年性发生。2020年8月,笔者在浙江省宁波市福泉山茶园调研时首次在浙江发现该虫呈区域爆发性为害茶树,为害面积约为53.3 hm^2。本文从大造桥虫的分类地位与分布,形态特征、生活习性与为害、防治措施几个方面对其进行了描述介绍,以供茶树植保工作者参考。
