调查了来自台湾、鼎湖山和南昆山的9个果蝇品系及其近亲在中国和缅甸的比诺温和仰光的求偶行为和生殖隔离。台湾和大陆中国株之间没有发现交配前和交配后的分离。中国大陆的中国(DHS和NKS)或TWN品系与MMY或RGN品系杂交，产生了可育的F1杂交雌性和不育的F1杂交雄性。MMY品系与RGN品系之间的杂交表现出很强的分离性，要么不产生F1杂种，要么产生可育的F1杂交雌性和不育雄性。这些结果表明，至少存在三个遗传上截然不同的兄弟种。
Courtship behavior and reproductive isolation between nine strains of Drosophila lini and its siblings from Taiwan (TWN), Dinghushan (DHS) and Nankunshan (NKS) in China, and Pyinoolwin (MMY) and Yangon (RGN) in Myanmar were investigated. No premating and postmating isolation between the Taiwan and mainland China strains were found. Crosses between mainland China (DHS and NKS) or the TWN strain and the MMY or RGN strain produced fertile F1 hybrid females and sterile F1 hybrid males. Crosses between MMY strains and RGN strains which showed strong premating isolation produced either no F1 hybrids, or fertile F1 hybrid females and sterile males in some cases. These results suggest the existence of at least three genetically distinct sibling species of D. lini.
