Rhipicephalus decoloratus infests a wide range of livestock. Control is mainly by acaricides based on a good knowledge of its reproductive life cycle. The ability of the control regime to effectively destroy the larvae, nymphs and the adults would enhance the success of the control strategy. Also the effectiveness of the control process is dependent on incorporating the effect of variations in physical parameters of the ecological zone and their effect on life cycle of the ticks. In this study, the life cycle of the tick was studied in the laboratory to maximize their survival and ascertain their possible maximum reproductive capacity so as to effectively develop the most acceptable acaricide control strategy for the tick. Engorged weight, fecundity, larval survival to adult tick, number of days for eggs to hatch to larvae and percentage survival of larvae to adult ticks were studied. Egg output per engorged female was 1720 to 3158 (p＜0.05), eggs needed 24 to 25 days (p＜0.05) to hatch to larvae and survival rate of larvae to adulthood was 25 to 47 (p＞0.05) per total number of eggs laid. Eggs output, hatching period did not differ from literature values. With this low survival rate, it should be possible to design an effective control strategy to reduce their menace on livestock production. We therefore concluded that current control methods especially, the use of acaricides based on the ticks reproductive life cycle should be maintained.
