Changes in the integument of nymphal and adult hyalomma [hyalomma] dromedarii koch[Acari: Ixodoidea: Ixodidae] I the effects of feeding and moulting

ABSTRACT

The integument of the dorsal alloscutum in nymphal and female H. dromedarii consists of the cuticle underlined by epidermis. The cuticle contains two layers, a thin external epicuticle and a thick internal procuticle. The procuticle is distinguished into an outer endocuticle and an inner endocuticle. Changes occuring in the cuticle and epidermis in symphal and adult H. dromedarii are correlated with moulting and feeding
