In Kenya, ticks and tick-borne diseases (TBDs) are a major constraint to further development of the livestock industry. Four tick-borne diseases, East Coast fever (ECF) which is caused by the protozoan parasite Theileria parva and transmitted by the tick Rhipicephalus appendiculafus, anaplasmosis and babesiosis both transmitted by Boophilus tick species and heartwater which is transmitted by Amblyomma tick species are prevalent in many cattle rearing areas. Currently, control of ticks through application of chemical acaricides is the main strategy used to control TBDs. The main method of acaricide application is through plunge dipping. In 1995, there were about 5,100 cattle dips in Kenya. However, such intensive tick control is difficult to sustain and is unlikely to be the most profitable control option. Integrated control options combining reduced use of acaricides with immunisation is being pursued as a potentially more profitable and sustainable method for controlling TBDs.
