对我国新疆地区的疟疾媒介米赛按蚊(Anopheles messeae Fall,1926)进行了唾腺多线染色体的研究,报道了多线染色体的核型照片和模式图。本研究还发现,米赛按蚊存在着4类种内多态性臂内倒位:①2R的杂合子倒位,②3R的杂合子倒位,③3L的杂合子倒位,④3L的纯合子倒位,并统计了倒位频率。新疆地区与苏联境内的米赛按蚊比较,多线染色体带型未见明显差异;多态性倒位类型相符,但频率不一致。 Polymorphism of the salivary gland in Anopheles messeae Fall (1926), a malaria vector in Xinjiang, China, was reported. Karyotype pictures and patterns of multiliner chromosomes were reported. This study also found that there are four kinds of intraspecific intramuscular inversions in A. mosquito: ① heterozygous inversions of 2R, ② heterozygous inversions of 3R, ③ heterozygous inversions of 3L, ④ homozygous inversions of 3L , And statistics upside down frequency. There was no significant difference in multi-line chromosome banding between Xinjiang Anopheles stephensi and Anopheles mosquitoes in the Soviet Union. The polymorphism was consistent with the inverted type, but the frequencies were inconsistent.
