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。
In order to explore the classification of Anopheles sinensis in China, we observed the salivary gland chromosomes of Anopheles sinensis from 1979 to 1982 in Zhengzhou, Shanghai and Youxi, Fujian Province. The salivary gland chromosomes of the 4th instar larvae of Aedes aegypti in 3 regions differed significantly from the 2R free ends except for a few details on each arm. The distribution of salivary gland chromosomes in Youxi, Fujian Province, is consistent with that of Anopheles sinensis in Shanghai, and is consistent with that in Zhengzhou. The three regions of Anopheles sinensis X chromosome similar. But bubble location, size and composition vary. In particular, the location of the bubble on the X chromosome differences most obvious. According to the comparison with Anopheles sinensis in Nanjing, the difference of the salivary gland chromosome patterns in the fourth instar larvae of Anopheles sinensis may be the reflection of the polymorphism prevailing in the biosphere.
