摘　　要：目的:观察广西凌云微小按蚊与云南元江微小按蚊之间是否存在生殖隔离。方法:分别在两地的牛房采集胞血的微小按蚊,在实验室单雌驯养2代,用人工交配方法进行杂交试验,观察子1代(F1)的可育性。结果:Y×L组的产卵率极低,卵的孵化率为0,卵内未见胚胎形成,显示不育。Y×F1的孵化率、化蛹率均明显低于亲本,可育性低。结论:广西凌云微小按蚊与云南元江微小按蚊已存在部分生殖隔离,系两个不同的亲缘种。Objective： To observe whether there is any reproductive isolation between Anopheles minimus from Lingyun （L）and Yuanjiang. （Y）. Methods. Anopheles minimus were collected from cattle sheds on the spot. Each isofemal line was set up in the laboratory. Hybridization experiments were conducted by using forced mating between Anopheles minimus from Lingyun and Yuanjiang, for observing the reproductive ability of F1 hybrids. Result. No embryo formation was found within the eggs produced by group Y♀ × L ♂ , with zero hatching rate was. Conclusion： Reproductive isolation did exist in Anopheles minimus from Lingyun and Yuanjiang.
