Morphofunctional investigations of five Ixodes species (Ixodes pacificus, I. pavlovsky, I. persulcatus, I. ricinus and I. scapularis) were carried out. It was established, that the change of midgut epithelium lags at the each next developmental stage, and it is not synchronized with general processes of metamorphosis and organogenesis during molts. The midgut epithelium of a previous phase of the life cycle persists and functions during the feeding stage at the next phase.
对五种硬蜱（太平洋硬蜱、巴甫洛夫硬蜱、全沟硬蜱、蓖麻硬蜱和肩突硬蜱）进行了形态功能研究。结果表明，中肠上皮的变化在每个后续发育阶段都滞后，并且在蜕皮过程中与变态和器官发生的一般过程不同步。生命周期前一阶段的中肠上皮在下一阶段的进食阶段持续存在并发挥功能。
