在人类盘尾丝虫病的传播中，黑蝇媒介的能力通过调节产生多少感染期幼虫来影响传播强度。这种疾病在厄瓜多尔日益加剧，在那里，Simueleciguum是一种高效的限制型病媒，就苍蝇发育成感染期幼虫的百分比和每只感染苍蝇的幼虫数量而言，可与非洲森林物种相媲美。与此相反，危地马拉和墨西哥南部的地方病疫源地保持稳定，并密切限制在幼虫发育地点周围。赭曲霉，一种表现出易化型能力的媒介，必须以具有相对较高微丝蚴血症的人为食，以产生大量感染期幼虫。这种比较表明，在规划盘尾丝虫病区域控制方案时，应包括媒介能力的评估。
In the transmission of human onchocerciasis, competence of the black fly vector influences intensity of transmission by regulating how many infective-stage larvae are produced. The disease is intensifying in Ecuador where Simulium exiguum is a highly efficient limitation-type vector comparable with African forest species in terms of the percentage of flies developing infective-stage larvae and the numbers of larvae per infected fly. In contrast, the endemic foci in Guatemala and southern Mexico have remained stable and closely circumscribed around larval development sites for S. ochraceum, a vector that exhibits a facilitation type of competence and must feed on people with comparatively high microfiladeremia to develop significant numbers of infective-stage larvae. This comparison indicates that assessments of vector competence should be included when planning regional control programs for onchocerciasis.
