摘要: 为了探讨我国中华按蚊种下分型的问题,我们于1979~1982年对郑州、上海和福建尤溪地区的中华按蚊唾腺染色体进行了观察。3个地区的中华接蚊四龄幼虫唾腺染色体,除了各臂上有若干细节不同外,以2R游离端的差异为明显。 3个地区中福建尤溪的唾腺染色体特征与上海地区中华按蚊特征的相符点比与郑州地区相符的为多,推想与地理差异有关。3个地区中华按蚊的X染色体基本相似。但泡的位置、大小和组成上存有差异。尤以泡在X染色体上的位置差异最为明显。根据与南京地区中华按蚊的比较结果,认为这些地区中华按蚊四龄幼虫唾腺染色体带型等的差异,可能是生物界中普遍存在的多态现象的反映。

Abstract: The chromosomes of salivary glands of Anopheles sinensis from Zhengzhou (Henan), Shanghai and Youxi (Fujian) districts were studied in 1979-1982 to detect their subspecies classification.The main differences among the gland chromosomes of the 4th instar larvae in these three districts were on the free ends of 2R besides tiny changes on each arm.The characteristics of chromosomes in Youxi was more identical with those in Shanghai than in Zhengzhou. It is seemingly due to the geographical variation.X chromosomes of Anopheles sinensis in these three districts were basically similar one to another, but they vary in position, size and component, especially in the puff position.Compared with Anopheles sinensis from Nanjing, the variance among salivary gland chromosomes of Anopheles sinensis 4th instar larvae renders another evidence of chromosomal polymorphism in the biological world as a whole.
