Abstract: Objective To make a clear understand of whether there are some difference or generative isolation among those Anopheles anthropophagus from Sichuan,Liaoning(Faku county) and Guangdong(Hengqin island) provinces of China.Methods Hybridization was carried out on Anopheles anthropophagus from Sichuan,Liaoning(Faku county) and Guangdong(Hengqin island),China.The salivary gland chromosome slides of their filial generations were checked.Results Generative isolation is not being existed on Anopheles anthropophagus from Sichuan,Liaoning(Faku county) and Guangdong(Hengqin island) provinces,mosquitoes from three provinces can mate by themselves in cages and produce their offspring and enlarge their numbers.The salivary gland chromosome on filial generation shows complete synapsis.Conclusion There is no generative isolation and species difference among Anopheles anthropophagus from Sichuan,Liaoning(Faku county) and Guangdong(Hengqin island) provinces.
