Acaricides resistance in Hyalomma anatolicum ticks collected from a Gaushala in Sirsa district, Haryana was investigated. FAO recommended adult immersion test (AID) was carried out using different concentrations of commercially available cypermethrin, deltamethrin, Amitraz and fipronil following 10 minutes’ immersion time and 14 days’ observation protocol. Probit analysis of the data revealed LC50 and LC95 to be 53.70ppm and 501.18 ppm for deltamethrin; 303.39 ppm and 3467.37 ppm for cypermethrin and 1602.83 ppm and 5574.42 ppm for Amitraz, respectively. There was complete inhibition of egg laying in ticks exposed to varied doses of fipronil, the lowest dose being 15ppm. The results indicated the emergence of acaricides resistance against cypermethrin, deltamethrin and Amitraz while fipronil was found to be highly effective in control of H. anatolicum ticks.
