摘要
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。
Salivary gland polyt-ne chromosome was studied in malarial vtctor Anopheles messeae Fall, 1926 of Xinjiang Uygar Zizhiqu.Photograph and diagram of polytene chromosomal karyotype were presented.Four types of intraspecific polymorphic paracentric inversion were found.They were heterozygous inversions in arm 2R and 3R,heterozygous inversion in 3L and its homozygous form.No obvious difference of polytene chromosomal bands was found between Xinjiang An.messeae and Soviet Union An.messeae and they shared the same polymorphic inversion form, but different inversion frequency.
