盘尾丝虫病媒S. ochraceu的卵发生特点是卵泡发育的不同阶段，包括出现、摄食糖和完成血餐。第一次排卵后卵巢的变化也被描述。该黑蝇属非自生体，具有淋养性。产卵后卵泡扩张的形成遵循一种独特的模式，在144小时内都有明显的细胞碎片痕迹。通过冷蒽酮试验检测到果糖的存在，表明产卵和未产卵的果蝇通常会吸收花蜜，这是它们觅食行为的一部分。花蜜的可用性和频繁使用可能对产蝇的寿命有显著贡献，从而增加其媒介潜力。
Oogenesis in S. ochraceu, Onchocerca volvulus vector, is characterized in terms of distinct stages of follicular development following emergence, sugar feeding and completion of a blood meal. Changes in the ovary following the 1st oviposition are also described. This black fly species was anautogenous and exhibited gonotrophic concordance. The formation of follicular dilatations after oviposition followed a distinct pattern with traces of cellular debris evident up to 144 h. The presence of fructose, as detected by the cold Anthrone test, indicated that parous and nulliparous flies routinely imbibe nectars as part of their foraging behavior. The availability and frequent use of nectar may contribute significantly to longevity of parous flies, hence increasing their vector potential.
