摘要 叶蝉是茶树上重要的刺吸性害虫， 常造成茶树芽叶萎缩不展，甚至焦边、糊叶。野外调查发现一种特殊的可造成茶树叶片大面积雪花状失绿的叶蝉若虫，采回室内经单头饲养后获得其成虫，并通过成虫外部形态和雄性外生殖器结构鉴定该害虫为帕辜小叶蝉Aguriahana paivana （Distant）。本文报道了该害虫在贵州的发现和为害，首次记述了帕辜小叶蝉若虫形态特征及其在茶树上的典型为害状，并提供了相应的彩色图片。

Abstract

The leafhoppers are extremely harmful piercing pest on tea plants and seriously threaten to tea plant （Camellia sinensis） cultivation. It usually leads to bud leaf shrinkage， even causes leaf tissue necrosis. Through field investigation， we found that a special leafhopper could cause mass of snow-like spots on tea leaves with heavy infestation， then we took back the nymph leafhoppers and fed with fresh tea leaves until all of them emerged into adults. Based on the adult morphological features and male genitalia observation， the leafhopper was identified as Aguriahana paivana （Distant）. This paper records its occurrence and damage in Guizhou， and firstly describes the morphological features of nymphs and typical infestation characteristics in tea plant. Identification pictures of adults， nymphs and male genitalia were also provided in the paper.

叶蝉是茶树最重要的刺吸性害虫类群之一，据统计，在我国为害茶树的叶蝉种类达60余种[1]，其中以小贯小绿叶蝉Empoasca onukii發生为害最为严重[2-4]，其他诸如茶新折缘叶蝉Neovulturnus testacea[5-6]、大青叶蝉Cicadella viridis[1]、茶扁叶蝉Chanohirata theae[7]等也能造成一定的为害，但绝大多数种类仅限名录性记载而对其发生为害情况报道甚少。叶蝉类害虫通常为害茶梢嫩茎嫩叶，造成茶树芽叶生长迟缓、萎缩不展，严重时产生焦边、糊叶，影响树势[7-8]。然而，笔者于2017年底在贵州茶树害虫调查过程中却发现一种造成茶树叶片产生雪花状失绿斑点的叶蝉，通过其成虫外部形态特征和雄性外生殖器解剖观察，鉴定该害虫为帕辜小叶蝉Aguriahana paivana。目前，关于帕辜小叶蝉的报道仅见于分类学研究中[9-10]，其生物学信息等所知甚少。本文将鉴定结果和为害特征作一报道，记录该害虫在贵州的发现和为害，并提供了该虫成、若虫的彩色图片，研究结果可为茶树害虫的识别鉴定和科学防治提供参考。……
