Abstract:
The life cycle of Hyalomma dromedarii (camel ticks) was
studied on cattle under experimental conditions from March to
July 2018 at range temperature 34.5 – 38.5°c and range
relative humidity 21 - 47 %. It behaved as three-host tick and
completed its life cycle in 97 – 131 at days. A total of 1500
larvae were fed 500 larvae for each cattle 1486 larvae were fed
on cattle (99.07%). The larval feeding period was found to be 3
– 17 days at mean temperature 38.5°c and relative humidity
21% and larval moulting periods 14 – 16 days. 300 nymph fed
on three cattle 296 nymphs were fed (98.7%) found nymph
feeding period 3 – 10 days at mean temperature 35.4°c and
relative humidity 26% and nymph moulting periods 14 – 15
days. 30 adult ticks were fed on three cattle that were able to
feed all 100% adult ticks found adult ticks feeding period at
mean temperature range 34.5°c – 35.5°c and relative humidity
range 28 - 47% . while the pre-oviposition period 4 - 6 days and
Pre-eclosion periods 16 -20 days. This type of ticks higher
weight recorded engorged adult 0.961 grams and has given the
highest numbers of eggs 9452 and the highest hatching rate
99.47% the engorged female recorded the lowest engorged
weight 0.620 grams gave the lowest number of eggs 5461 and
hatching rate 95.24%.
