Abstract
Ticks are widely distributed in most of regions of the world in tropical and subtropical regions including India. Hyalomma anatolicum are the commonest tick species in India infesting cattle and buffaloes and cause significant economic losses to diary and leather industries by adversely affecting the milk production and quality of hides. Synthetic pyrethroid (deltamethrin) and formamidine (amitraz) have been used to control Hyalomma anatolicum in most part of Hisar, Haryana. Which result in development of resistance against both the acaricides. Collection of the ticks were done from different gaushalas around Hisar, Haryana. Then these ticks were subjected to adult immersion test with a discriminating dose (AITDD) against deltamethrin and amitraz. Results revealed high degree of resistance against Deltamethrin 76.6% and 93.3% in R.(B.) microplus and Hyalomma anatolicum ticks of Gurana and Mangali region respectively. Which may be due to long time exposure to pyrethroids or may be due to inappropriate application of deltamethrin in tick infestation. In case of amitraz prevalence of resistance is low in comparison with deltamethrin, which was 23.3% in R.(B.) microplus ticks collected from Gurana region.
