目的 了解中国嗜人按蚊的分布 ,判定辽宁法库县、广东横琴岛可疑嗜人按蚊和四川嗜人按蚊是否存在生殖隔离 ,有无种间差异 ,是否为同一蚊种。方法 采用遗传学方法进行人工杂交 /自然交配 ,并对杂交后的子代进行多腺染色体制片观察。结果 辽宁法库县、广东横琴岛可疑嗜人按蚊与四川嗜人按蚊亲代杂交、回交、子代自交均能产生正常子代 ,并能大量繁殖。子代唾腺染色体制片观察未发现不联会现象。结论 辽宁法库县、广东横琴岛可疑嗜人按蚊与四川嗜人按蚊不存在生殖隔离 ,也无种间差异 ,系不同地域分布的同一种嗜人按蚊。
Objective To understand the distribution of Anopheles anthropophagus in China, and to determine whether there is reproductive isolation, whether there is inter-species difference or not among the same mosquito species in the faulted anopheles and the anopheles sinensis in Faku County of Liaoning Province and Hengqin Island of Guangdong Province. Methods Genetic methods were used for artificial mating / natural mating, and the progeny of the hybrids were observed by polychromatic chromosome. Results In Liaoning Faku County and Guangdong Hengqin Island, the anopheles anthropophagus and An. Children’s salivary gland chromosome production observed no association phenomenon. Conclusion There is no reproductive isolation between An. An. Sinensis and An. An. Sinensis in Faku County, Liaoning Province and Hengqin Island in Guangdong Province. There is no inter - species difference between the two species. They are the same kind of Anopheles anthropophagus distributed in different regions.
