Abstract: Rhipicephalus (Boophilus) microplus, commonest tick species in India, cause significant economic losses to dairy and leather industries by adversely affecting the milk production and quality of hides. Tick control strategy involves mainly the use of synthetic acaricides which results into development of acaricide resistance. In the present study, the resistance status of Rhipicephalus (Boophilus) microplus against commonly used acaricides was evaluated by standardized method of FAO. The tick samples were collected from cattle owned by livestock holders to determine the status of development of acaricide resistance to Deltamethrin and cypermethrin using larval packet test. The results indicated that isolates of R (B) microplus has developed resistance to deltamethrin and cypermethrin. The data on field status of acaricide resistance will be helpful to adopt suitable strategy to overcome the process of development of resistance in ticks.
