Tick distribution pattern in India and Overview on possible methods for their control
Ticks have a major impact on husbandry, productivity and welfare of domestic animals. They are responsible for substantial economic losses to the livestock industry directly through dermatitis, weight loss, loss of quality of hides, itching, irritation, anaemia and indirectly through transmitting viral, rickettsial, bacterial and protozoan diseases. The studies show that prevalence of ticks has a seasonal distribution, preferable host selection and also depends on rearing practices adopted by small holders and the rearers. Ticks have been controlled by using chemical acaricides since past several decades, but, the method has been posing several deleterious effects including environmental pollution and resistance development. Therefore, focus is given on several alternative methods to control the ticks. The present paper deals with the distribution pattern of ticks in India and possible factors that affect their prevalence. The paper also discusses several strategies (conventional and alternatives) for tick control.
