非洲热带实蝇属Ceratitis MacLeay是一个重要的经济类群，包括超过89种，细分为6个亚属。形态学和寄主利用特征的分支系统学分析产生了几个属的系统发育假说。只有单系的Pardalaspis和Ceratitis亚属（严格意义上）和多系的Ceratalaspis亚属是共同的所有这些属。在这项研究中，从形态和主机使用字符的假设进行了测试，使用基因树产生的两个线粒体基因（细胞色素氧化酶1和NADH脱氢酶亚基6）和核基因（周期）的DNA序列数据。基因树比较表明，Pardalaspis亚属为单系，Pterandrus亚属A亚组为单系，Pterandrus亚属可能为并系或多系，Ceratalaspis亚属为多系，Ceratitis s亚属为多系。S.可能不是单系的此外，Ceratitis属和Trirhithrum属在基因树中没有形成单系分支。虽然数据在统计学上拒绝单系下田-长谷川测试下的三色菊，他们不拒绝单系的Ceratitis。(c)2005年爱思唯尔公司All rights reserved.
The Afrotropical fruit fly genus Ceratitis MacLeay is an economically important group that comprises over 89 species, subdivided into six subgenera. Cladistic analyses of morphological and host use characters have produced several phylogenetic hypotheses for the genus. Only monophyly of the subgenera Pardalaspis and Ceratitis (sensu stricto) and polyphyly of the subgenus Ceratalaspis are common to all of these phylogenies. In this study, the hypotheses developed from morphological and host use characters are tested using gene trees produced from DNA sequence data of two mitochondrial genes (cytochrome oxidase 1 and NADH-dehydrogenase subunit 6) and a nuclear gene (period). Comparison of gene trees indicates the following relationships: the subgenus Pardalaspis is monophyletic, subsection A of the subgenus Pterandrus is monophyletic, the subgenus Pterandrus may be either paraphyletic or polyphyletic, the subgenus Ceratalaspis is polyphyletic, and the subgenus Ceratitis s. s. might not be monophyletic. In addition, the genera Ceratitis and Trirhithrum do not form reciprocally monophyletic clades in the gene trees. Although the data statistically reject monophyly for Trirhithrum under the Shimodaira-Hasegawa test, they do not reject monophyly of Ceratitis. (c) 2005 Elsevier Inc. All rights reserved.
