Tick - borne livestock diseases and their vectors. 4. Chemical control of ticks
Ticks are a problem because they transmit diseases, produce paralysis or toxicosis, and cause physical damage to livestock. Although only relatively few of the more than 700 species of ticks in the world are of importance to man and his domestic animals, these few species must be controlled if livestock production is to meet world needs for animal protein. Losses due to tick infestations can be considerable. For example, in Australia alone in 1974, losses due to the cattle tick (Boophilus microplus) were estimated to be US 62 million. The main weapon for the control of ticks at present is the use of chemical acaricides. In this article the need for tick control is reviewed and techniques for applying acaricides to animals, classes of acaricides, strategies of tick control, and precautions when using acaricides are discussed
