This preliminary report provides information concerning genetic variation in the vector mosquito Anopheles pseudopunctipennis sensu lato that could have malaria control implications. Because of inconsistencies in malaria transmission patterns within geographic zones inhabited by this vector, the possibility that it represents a species complex was investigated. Hybrid crossing studies, electrophoretic analysis of enzyme variation, and DNA restriction studies were carried out in mosquitoes captured in nine areas of Mexico, Bolivia, and Peru. The findings demonstrated the existence of a species complex believed to have resulted from allopatric speciation. This research points to a need for establishing the geographic distribution of the newly recognized species because of their potential influence on malaria control.
本初步报告提供了有关媒介蚊虫伪点按蚊复合组（Anopheles pseudopunctipennis sensu lato）遗传变异的信息，这些信息可能对疟疾控制具有重要意义。由于在该媒介所栖息的地理区域内疟疾传播模式存在不一致性，因此对其是否代表一个复合种的可能性进行了调查。在墨西哥、玻利维亚和秘鲁的九个地区捕获的蚊虫中开展了杂交研究、酶变异的电泳分析以及DNA限制研究。研究结果表明存在一个据信由异域物种形成导致的复合种。这项研究指出，鉴于新确认的物种对疟疾控制的潜在影响，有必要确定它们的地理分布。
