A study of the vectors of onchocerciasis was carried out in 1961 in northern Venezuela at the request of the Venezuelan Government. This article, based on the report submitted, records various observations made-mainly during the dry season-on the identification and biology of the Simuliidae and on the possibilities of controlling them.Twelve Simulium forms were encountered; special attention was paid to the two common man-biting species; S. exiguum, which was abundant but of uncertain relation to onchocerciasis, and S. metallicum. The authors conclude that S. metallicum is the main or only vector in the area studied, but that S. exiguum might possibly also transmit onchocerciasis in certain places near large streams where it is found in great numbers.
1961 年，委内瑞拉政府要求在委内瑞拉北部进行盘尾丝虫病病媒研究。本文根据提交的报告记录了在识别和研究 Simuliidae 以及控制它们的可能性方面所做的各种观察结果——主要是在旱季进行的。共遇到 12 种 Simulium 形态，特别关注两种常见的叮咬人类的物种：大量存在但与盘尾丝虫病关系不确定的 S. exiguum 和 S. metallicum。作者得出结论，S. metallicum 是研究区域的主要或唯一病媒，但在靠近大型溪流的某些地方，大量存在的 S. exiguum 也可能传播盘尾丝虫病。
