title: A possible pathway of chitin synthesis as revealed by electron microscopy in Tetranychus urticae (Acari, Tetranychidae).
abstract: Two chitin synthesising systems in Tetranychus urticae area described: one chitosomal system located in the oocytes where spatial and temporal distances are large, and one membrane bound system located in the hypodermis. Similarity of mechanisms of chitin synthesis in animals and plants is suggested.
