The formation of the peritrophic membrane in adult female mosquitoes, Culex tarsalis, was examined by light and electron microscopy. The initial evidence of secretion of peritrophic membrane precursors occurred at 8-12 h after ingestion of the bloodmeal. Morphogenesis of the peritrophic membrane occurred within 12-16 h after the initial secretion; culminating with a fibrous, multilayered peritrophic membrane 20-24 h after bloodmeal ingestion. A discussion of the potential participation of the peritrophic membrane in a midgut barrier to infection by arboviruses is presented. The participation of the peritrophic membrane in a midgut barrier to infection of C. tarsalis, and many other mosquito species, by arboviruses is considered a moot point.
利用光学显微镜和电子显微镜对成年雌性致倦库蚊中围食膜的形成进行了研究。围食膜前体分泌的最初迹象出现在吸食血餐后8至12小时。围食膜的形态发生在最初分泌后的12至16小时内；在吸食血餐后20至24小时形成纤维状、多层的围食膜。文中讨论了围食膜在中肠对虫媒病毒感染的屏障作用中的潜在参与情况。围食膜在致倦库蚊以及许多其他蚊种的中肠对虫媒病毒感染的屏障作用中的参与情况被认为是一个有争议的问题。
