The formation of the peritrophic matrix in the midgut of females of 5 ixodid tick species (Ixodes pacificus, I. pavlovskyi, I. persulcatus, I. ricinus and I. scapularis) was studied by means of light and electron microscopy in different periods of the feeding and after detachment. The formation of the peritrophic matrix started when the first food portions came into the gut lumen, 9-12 hours after the attachment. Renovation of the peritrophic matrix took place during the whole feeding period; every new generation of midgut cells synthesized their own matrix. It was deposited on the apical surface of every midgut cell in the beginning of differentiation, and was functioning during the life of the cell. The peritrophic matrix separates spaces of the cavitary and cytozoic digestions.
通过光学显微镜和电子显微镜，研究了5种硬蜱（太平洋硬蜱、帕氏硬蜱、全沟硬蜱、蓖麻硬蜱和肩突硬蜱）雌蜱在进食不同阶段及饱血后中肠围食膜的形成情况。围食膜的形成始于附着后9 - 12小时，当第一批食物进入肠腔时开始。在整个进食期间围食膜都在更新；每一代中肠细胞都会合成自己的围食膜。它在分化开始时沉积在每个中肠细胞的顶端表面，并在细胞存活期间发挥作用。围食膜分隔了腔外消化和细胞内消化的空间。
