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.

This article about a mite or tick is a stub. Egg surface following chorion removal was not smooth Fig. Mouth enclosed 2 cheliceral digits, each terminated with 3 lobes.

You do not currently have access to hyallmma article. Length of each opening was 8. Merging of these vesicles, originated from Golgi complex and rough endoplasmic reticulum of the developing oocyte, was formerly observed in Amb.

The second type was numerous, slit-like and without rings or lips.

Patella length was Both polar and lateral zones of the egg surface contained numerous openings Fig. Each technique showed some characters.

Arrows points to large openings. Fine structure of the hyalonma of Argas persicargas persicus oken ixodoidea argasidae. Hyalomma Hyalomma dromedarii, the camel tick, is distributed in deserts, semideserts and steppes from northwestern India and southern USSR to Arabia and Africa north of the equator wherever camels occur Hoogstraal et al.

Extensible part of the idiosoma showing horizontal dromedarji, festoons and setae. Hyapomma and Rhipicephalus decoloratus Infesting Cattle in Uganda. Egg shell was also perforated particularly at poles. Don’t have an account? Terminally the dorsolateral and ventral plates enclosed the mouth opening in which 2 cheliceral digits were arisen from lateral sides Fig.

Scanning electron microscopy study of the egg of Haemagogus Haemagogus capricornii Lutz Dromedarrii You could not be signed in. Two openings were noticed on the dorsal side of basis capituli Fig. The hypostome extended anterior to the basis capituli.

Egg incubation, nymphal premolting, and female preoviposition and oviposition periods were prolonged with decrease in temperature.

Finally, they were subjected to critical point drying in order to complete the dehydration process Junkum et al. Morphological characterization of the ovary and vitellogenesis dynamics in the tick Amblyomma cajennense Acari: Immatures may feed on camels but commonly infest a wide variety of wild rodents and also lizards, birds, hedgehogs and hares Hoogstraal, Leg segments were built of heavily sclerotized cuticle and joined to each other by highly movable articulation of flexible cuticle.

Higher magnification of small openings showing their lack to outer rings or internal lips. These setae were thick hair-like and terminated with rounded tips Fig. SEM investigation of the larva revealed smooth scutum with slight irregular ornamentation and horizontally folded extensible cuticle with vertical ridges. This was followed by rinsing twice with PBS and dehydrating with alcohol. In other projects Wikimedia Commons Wikispecies.


Larvalnymphal and female feeding periods of this two-host tick were not affected by temperature. Less common hosts of adults are sheep, buffaloes, horses, donkeys and mules. Rare studies were concerned with the morphology of acarine eggs particularly those using SEM technique. This page was last edited on 5 Octoberat Redescription of all Parasitic Stages of H. Each leg was divided into 7 primary segments Fig.

Don’t already have an Oxford Academic account? With the purpose of presenting exact description of acarine eggs, it is preferable to examine them both with and without SEM processing. In order to accurately examine H. Related articles in Web of Science Google Scholar.

This most likely allows anteroventral movement only for the capitulum. Each palp consisted of 4 segments. Dorsal view of the capitulum. The present study also presented more measurements similar or greater than those carried out by many authors in other tick species in order to be useful for instructing keys based on larvae for classifying Hyalomma species.

Special thanks are also due to Prof. SEM processing caused partial removal of the chorion which made the egg shell clear and easily observed.

These setae were simple, short and pointed Fig.
