Abstract
Two types of hard tick have been collected and identified belongs tothefamily Ixodidae called :Hayalomma anatolicum anatolicum and Rhipicephalus sanguineus sanguineus, after checking the description of the external features of both types. The tick samples have been collected between the periods from 5/4/2009 till 30/3/2010. Four regions have been chosen randomly for collecting the tick samples in Nineveh:(Goggchali, college ofagriculture and forestry field/animal husbandry department, veterinary medicine hospital area/ Al-hadbaa region and Veterinary medicine hospital area/Bab senjar). The sample were collected from three types of Animals with economic importance, have been selected, which considered as a suitable places for hard tick developing : the cows, sheep, and dogs. The rabbits as (experimental animals) and incubator were used to complete tick life cycle. in both which provides the proper temperature, and relative humidity in all seasons of the year according to the changes which takes place in the external milieu.The aim of the research includes a comparison of the life cycle. The first trial of the life cycle in spring took (67-68) days for Hayalomma anatolicum anatolicum and (88) day for Rhipicephalus sanguineus sanguineus, studying the life cycle during the summer took (58) days for Hayalomma anatolicum anatolicum and (87) days for Rhipicephalus sanguineus sanguineus, whereas during autumn took (71) days for Hayalomma anatolicum anatolicum and (118) days for Rhipicephalus sanguineus sanguineus, whereas the fourth trial of life cycleduring winter took (131) days for Hayalomma anatolicum anatolicum and (143)days for Rhipicephalus sanguineus sanguineus. A comparison was made to check the rates of eggs hatching into larvae, and the rates of the nymph weight for the engorged weight and percentages for the engorged nymph and the rates of the females number, and the percentages of the congested females before and after oviposition of the eggs. Also observed the rates and the range of eggs weight blocks, and the number of the eggs for both types of ticks.During the life cycles studied the optimum temperature and the relative humidity measured for each season which eventually had affected the life cycle of the ticks.
