The ovipositional pattern of fully engorged adult female Rhipicephalus sanguineus infesting sheep was studied under belljar conditions of mean ± SD (range) temperature of 25.4±2.16 (23-29oC) and relative humidity 90% and ambient conditions of 26.4±2.4 (23.6-31.6oC) and relative humidity 63.0±3.93 (51.3-72%). The pre-oviposition days under belljar conditions (11.1±9.15) was significantly shorter (p0.05) under belljar (22.3±9.69) than ambient (23.7±10.7) conditions with the total mean ± SD number of eggs laid under each condition as 1021.9±1082.4 and 1096.9±1173.0 respectively (p
