摘要:本文描述了目前我国目前仅有的两种橘小实蝇复合种--橘小实蝇与泰国果实蝇的主要形态鉴别特征,并提供了详细的图片资料。两者的主要区别在于泰国果实蝇胸部缝后侧黄条较短,终止于内后翅上鬃之前;腹部第2背板前缘黑色条带较橘小实蝇更宽;橘小实蝇腹部第3-5背板中央有一条出烟褐色的纵带组成的"T"形,而泰国果实蝇腹部,除第4-5背板除黑色中纵条两侧外,均为黑褐色。

Morphological identification of Bactrocera dorsalis and Bactrocera thailandica
Abstract:This paper described the morphological characteristics of Bactrocera(Bactrocera)dorsalis (Hendel)and Bactrocera thailandica Drew & Hancock which are similar in external appearance. Meanwhile sharp photographs for different parts of each species are provided. B. thailandica differing primarily from B. dorsalis by having shorter lateral postsutural vittae, ending before a level of intra-alar setae; abdominal tergum 1 black except for a narrow orange-brown band along posterior margin but not reaching lateral margins, terga 3-5 predominantly dark fuscous to black with a red-orange to red-brown narrow submedial markins over terga 4-5 and the posterior part of tergum 3.
