This study will focus on control of the Brown Ear tick, Rhipicephalus appendiculatus. The preference of the R. appendiculatus for feeding on the ears of their hosts makes this species a prime candidate for control by acaricide-impregnated ear tags. Although this tick is not the only tick species commonly found on livestock in East Africa, its presence often dictates the frequency with which cattle should be dipped or sprayed (currently up to twice a week with unsafe products) because of the damage caused to the ears by high tick burdens and the risk for East Coast Fever.
The MSc student will conduct field trials to assess the efficacy of a commercial ear tag to control ticks on cattle. The availability of a convenient, safe, efficient solution to control this tick species would be a game changer in tick- and tick-borne disease control in East Africa serving.
