dc.description.abstract This study was carried out to determine the seasonal infestation rate of Amblyomma lepidum on cattle under field conditions. Tick collection was carried out on a monthly basis for two consecutive years. Tick burden, stage and sex ratio were recorded. The results indicated marked seasonal variations on the infestation rate of cattle by the different stages of the tick Amblyomma lepidum. The tick infestation started to increase during the first shower and reached a peak towards or shortly after the end of the rainy season. Tick load declined during the cool dry season to become very low or almost nil during the hot dry season. Compared to the first year, larvae in the second year were significantly high (P≤0.01). Other stages were almost the same with only minor negligible differences. Season and breed significantly affected the infestation rate (P≤0.001). The effect of age on the infestation by female ticks was insignificant, but it affected the larvae and males (P≤0.01) and nymphs (P≤0.05). On the other hand, the effect of animal sex on the infestation by larvae was insignificant, while it significantly (P≤0.01) affected other stages. en_US
