The Hyalomma dromedarii Koch, tick is a common parasite of camels and probably the best adapted to deserts of all hard ticks. Like other. Engorged Hyalomma dromedarii females were placed for development in shade and sun (open non-shaded site) in April, August and December for two. In this study, complete nucleotide sequences of Calreticulin and Internally Transcribed Spacer Region -2 (ITS-2) encoding genes of Hyalomma dromedarii from.

Aggregates of granular patches were irregularly scattered between openings Fig. Tegument of posterior margin was subdivided into 9 festoons Fig. Kawther El-Kammah for her support with a number of valuable references. Leg segments were built of heavily sclerotized cuticle and joined to each other by highly movable articulation of flexible cuticle.


Absence of ovicidal effects of fenoxycarb in the tick Ixodes dammini as observed by light scanning and transmission electron microscopy. Presence of these openings from larva up to female possibly indicated an important function of the glands below them.

Scutum had broadly rounded posterior margin and carried 2 pairs of medial and 1 pair of marginal small and pointed setae Fig. This greatly supports the opinion of Balashov in female H. Morphological characterization of the ovary and vitellogenesis dynamics in the tick Amblyomma cajennense Acari: In order to view specimens, they were first attached with double-sided carbon tape to aluminum stubs so that they could be coated with gold in a sputter-coating apparatus JEOL JFC These specimens are referred to herein after as unprocessed.

However, the egg incubation and preoviposition periods were most greatly affected.

Egg shell was not rigid and might crumple particularly gyalomma polar zones Fig. Spotted fever rickettsiae in ticks from the northern sinai governate Egypt. Extensible part of the idiosoma showing horizontal foldings, festoons and setae. At least 2 types of cuticular openings were noticed on the extensible cuticle of the idiosoma. Clarification of the status of Rhipicephalus kochi Donitz, Ixodoidea, Ixodidae.

Physiology of ticks Pergamon Press, Oxford, pp: They were then placed in absolute alcohol hyallomma 10 min for 2 changes.

Eyes positioned at point of maximum width of the scutum Fig. Don’t already have an Oxford Academic account? The latter was wrinkled into folds of extensible cuticle and carried 1 pair of curved true claws.

Simple conical, conical with lateral expansions or irregularly shaped bumps which looked like to be externally coated with the chorion and observed between the egg shell and the chorion probably represented some sort of excreta of the developing embryo passed from the egg shell or debris passed from the outside through the chorion slits. Abstract The present study describes the egg of Hyalomma H.

Special thanks are also due to Prof. This was followed by rinsing twice with PBS and dehydrating with alcohol.

Such openings were not previously observed in SEM studies carried out on larvae of O.
