Polytene chromosome studies were undertaken to elucidate taxonomic relationships among populations of Anopheles aquasalis and A. emilianus in Venezuela. Four collection sites were chosen: two in Sucre state (Santa Fe and Guayana) where A. aquasalis (considered to be A. emilianus by Gabaldón and Escalante) is presumed to be the major regional vector of Plasmodium vivax; and two in areas where no malaria transmission occurs (Caño Rico, Aragua state, and Puerto Cabello, Carabobo state). The chromosome banding pattern of the four populations was identical and conformed to the standard chromosome map of A. aquasalis from Brazil. These results suggest that the population from Santa Fe and Guayana, considered to be A. emilianus, is conspecific with A. aquasalis. However, its status as a distinct species with a homosequential polytene chromosome banding pattern cannot be ruled out.
开展了多线染色体研究,以阐明委内瑞拉的咸水按蚊和埃氏按蚊种群之间的分类关系。选择了四个采集地点:两个在苏克雷州(圣菲和圭亚那),在那里咸水按蚊(加瓦尔东和埃斯卡兰特认为是埃氏按蚊)被认为是间日疟原虫的主要区域传播媒介;另外两个在没有疟疾传播的地区(阿拉瓜州的卡尼奥里科和卡拉沃沃州的卡贝略港)。这四个种群的染色体带型相同,符合来自巴西的咸水按蚊的标准染色体图谱。这些结果表明,来自圣菲和圭亚那的种群,被认为是埃氏按蚊,与咸水按蚊是同种。然而,不能排除其作为具有同序列多线染色体带型的独特物种的地位。
