为害陕西眉县猕猴桃的小绿叶蝉族害虫学名更正

Identifying the species of Empoascine pests damaging kiwifruit in Meixian, Shaanxi

【目的】明确为害陕西眉县猕猴桃园的小绿叶蝉族害虫学名和形态特征,对首次发现的优势种多型现象进行描述。【方法】采用网捕法采集小绿叶蝉族成虫,用相机拍摄相关生态照片;在体视解剖镜下观察标本形态特征,进行分类鉴定,对主要形态特征进行拍照。【结果】为害陕西眉县猕猴桃的小绿叶蝉族害虫有单片膜瓣叶蝉Membranacea unijugata Qin&Zhang,2011、广道小绿叶蝉Empoasca(Empoasca)hiromichi(Matsumura,1931)和松田小绿叶蝉Empoasca(Empoasca)matsudai(Dworakowska,1972);本研究共采集小绿叶蝉族标本685头,其中单片膜瓣叶蝉有深色型(均为雄性)88头,浅色型472头(包括雄性13头、雌性459头),该种标本数占所采标本总数的81.75%,广道小绿叶蝉和松田小绿叶蝉的标本数量分别占标本总数的17.66%和0.58%。【结论】为害陕西猕猴桃的小绿叶蝉族害虫优势种是单片膜瓣叶蝉,其成虫存在多型现象。我国猕猴桃的其他小绿叶蝉族害虫学名有待进一步调查明确。

[Objectives]To identify the empoascine species damaging kiwifruit in Meixian county,Shaanxi province and describe the polymorphism of the dominant species.[Methods]A sweep net was used to collect specimens and a camera to take habitat photos in the field.Microscopes were used to observe morphological characters and main diagnostic features were photographed.[Results]Three species were identified,Membranacea unijugata Qin&Zhang,2011,Empoasca(Empoasca)hiromichi(Matsumura,1931)and Empoasca(Empoasca)matsudai Dworakowska,1972.A total of 685 specimens were collected,of which Membranacea unijugata accounted for 81.75% of all specimens and Empoasca(Empoasca)hiromichi and Empoasca(Empoasca)matsudai for 17.66%and 0.58%,respectively.The M.unijugata specimens included 88 dark-colored males and 472 light-colored individuals(13 males and 459 females).[Conclusion]The dominant empoascine species damaging kiwifruit in Meixian county,Shaanxi province is M.unijugata,the adults of which are polymorphic.Further investigation is required to identify other empoascine species damaging kiwifruit in China.
