我国米赛按蚊有丝分裂染色体和种内多态观象的研究

Study on Mitotic Chromosome and Intraspecific Polymorphism of Anopheles messeae in China

作者对我国米赛按蚊(Anopheles messeae Fall,1926)进行了有丝分裂染色体核型和异染色质带的研究。发现了性染色体的种内多态现象,并论证了这种多态现象可能是由于结构异染色质在数量和分布上的多态现象引起。结果提示,染色体核型和分带研究在按蚊近似种团的分类中具有一定的价值。

Smear method was used to study the mitotic chromosomal karyotype and heterochromatin-banding of Anopheles messeae in Xinjiang Uygar Zizhiqu of north-west China. Intraspecific polymorphisms were found in sex chromosome. It is explained that these polymorphisms were formed by variation in heterochromatin quantity and distribution. The result suggests that chromosomal karyotype and banding are valuable in anopheline identification especially in species complex.
