Rhipicephalus sanguineus (Latreille, 1806) was reared under laboratory conditions of27± 3° C and 75± 5% R. H., for three generations. The mean of life cycle duration was 41- 73 days. The conversion efficiency index (CEI) was 0.3130± 0.173, the reproductive efficiency index (REI) was 33257.9± 14895.7 and the reproductive fitness index (RFI) was 9288.6 ± 4481.9. The males/ females ratio was 1.1 :1. Females fed for 9± 1.16 days. Pre-oviposition and oviposition periods were 4.0± 0.81 and 7.5± 1.72 days respectively. Number of oviposted eggs per female averaged 4598± 429.7. A positive correlation was observed between the weight of engorged female and number of its deposited eggs (r= 0.76). However, the highest number of eggs was recorded on the 4th day (1751 eggs/ female). Pre-hatching period was 15± 1.87 days and hatching rate was 92.4 %. Larvae and nymphs feeding periods were 4.5± 1.16 and 5.5± 1.12 days respectively.
