Abstract

The integument of Argas persicus was investigated using light, scanning and transmission electron microscopy. The study revealed that two layers, viz. an outer epicuticle and an inner procuticle, form the cuticle. The epicuticle includes wax, cuticulin and protein epicuticular layers. The wax layer carries numerous crater-like deposits, oval or circular discs and numerous infoldings. The procuticle contains an exo-, endo- and a subcuticle.Underlining the cuticle, flattened epidermal cells are connected via desmosomes and contain rough endoplasmic reticulum, free ribosomes and mitochondria. Scattered dermal glands are located beneath the cuticle and are continuous with the outside through dermal ducts and surface pores.
