从东南亚进口水果截获桔小实蝇复合种五近缘种的鉴别(双翅目:实蝇科)

介绍了近年从进口东南亚水果中经常截获的、最具经济重要性的桔小实蝇复合种5个近缘种:杨桃实蝇B.carambolae、桔小实蝇B.dorsalis、芒果实蝇B.occipitalis、木瓜实蝇B.papayae及菲律宾实蝇B.philippinensis,分别记述了翅、胸、足、腹及雌虫产卵器主要鉴别特征,并列出桔小实蝇复合种5近缘种鉴别特征检索表。

桔小实蝇5个重要复合种分类动态

桔小实蝇复合种已记录达100种,其中近十种是国际重要的经济意义种类。桔小实蝇复合种分类鉴定复杂,其中以杨桃实蝇(B.carambolae Drew&Hancock)、桔小实蝇(B.dorsalis Hendel)、木瓜实蝇(B.papayae Drew&Hancock)、菲律宾实蝇(B.philippinensis Drew&Hancock)和入侵果实蝇(B.invadens Drew,Tsuruta&White)等5个重要复合种的分类鉴定争议最大。本文介绍了桔小实蝇复合种的演化历史、5个重要复合种的分类特征及其最新研究进展。形态学、分子生物学和化学生态等新证据表明,杨桃实蝇是有别于桔小实蝇的独立种,桔小实蝇、木瓜实蝇、菲律宾实蝇和入侵果实蝇等其他四种为同一生物种,菲律宾实蝇是木瓜实蝇的同物异名种,桔小实蝇是木瓜实蝇和入侵果实蝇的高级同物异名种。5个复合种分类地位的变化已得到大多数实蝇专家的普遍认同,对桔小实蝇复合种的检疫和国际贸易中的生物安全有重要意义。
