Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae: Phlebotominae) is a vector of visceral leishmaniasis in the Americas and it might represent a complex of sibling species. Reproductive isolation between closely related species often involves differences in courtship behaviour. cacophony (cac) and period (per) are two Drosophila genes that control features of the "lovesong" males produce during courtship that has been implicated in the sexual isolation between closely related species. We are using gene fragments from L. longipalpis' homologues of these two genes to study the speciation process in this putative species complex.
长须罗蛉（Lutzomyia longipalpis）（Lutz & Neiva，1912年）（双翅目：毛蠓科：白蛉亚科）是美洲内脏利什曼病的传播媒介，它可能代表一个姐妹物种复合体。近缘物种之间的生殖隔离通常涉及求偶行为的差异。刺耳（cacophony，cac）和周期（period，per）是两个果蝇基因，它们控制雄性果蝇在求偶期间产生的“情歌”特征，这与近缘物种之间的性隔离有关。我们正在使用这两个基因的长须罗蛉同源基因片段来研究这个假定的物种复合体的物种形成过程。
