Drop-off rhythms and survival periods of Hyalomma dromedarii (Acari: Ixodidae) fed on camels (Camelus dromedarius) in the Sudan

Drop-off rhythms and survival of Hyalomma anatolicum (Acari: Ixodidae) fed on crossbred (Friesians x Zebu) calves in Sudan

“…Similar results were obtained by Ahmed (1987 cited in El Ghali et al 2003b) who stated that larvae are slightly more resistant to desiccation than nymphs, and Londt and Whitehead (1972 cited in El Ghali et al 2003b) working on water balance of larvae stated that both dead and live larvae responded similarly [29]. El Ghali and Hassan stated that it is possible that H. dromedarii larvae are more resistant to the desiccation than larvae of H. anatolicum [33]. This finding is possibly attributed to the fact that all stages of H. anatolicum infest cattle in cattle-sheds which may account for its shorter longevity [24].…”

Life Cycle of Hyalomma dromedarii Ticks (Acari: Ixodidae) on Sheep under Experimental Conditions

“…Alahmed and Kheir [17] reported that this tick behaved as a two-host tick when fed on rabbits. A similar finding was also documented in Northern Sudan where they found that this tick behaved as a two-host tick when fed on camels [20]. This variation in the type of life cycle of H. dromedarii based on the host species prompted us to investigate the feeding behavior of this tick fed on sheep and drop-off rhythms.…”

“…Likewise, ELGhali [19] documented that H. dromedarii on sheep and cattle is a three-host tick. In contrast, this tick behaved as a two-host tick when fed on camels under field conditions in Sudan and on rabbits under laboratory conditions [17,20]. In other studies performed in Iran, they found that H. dromedarii behaved as a one-host tick on camels [24].…”

Molecular Assay Proves the Presence of Theileria annulata Infection in Camels in Al-Diwaniyah Province, Iraq

“…Since then, T. camelensis and T. dromedarii have been recorded in Turkmenistan, Egypt, Somalia, India and Saudi Arabia ( 9 , 10 ). Little is known about these two species, and since only erythrocytic piroplasm stages have been observed, so their classification is not clear yet ( 11 ).…”
