Abstract

The resistance status against deltamethrin, cypermethrin, coumaphos and ivermectin was assessed of Rhipicephalus microplus from five districts of Uttarakhand, through adult immersion test and larval packet test. The field isolates were highly resistant to deltamethrin (median resistance ratio [RR50] = 9.10–29.13-fold) followed by cypermethrin (2.23–3.55). Surprisingly the isolates were susceptible to coumaphos (0.34–3.17). Emerging resistance against ivermectin (1.55–3.27) was also observed in all the isolates. Elevated levels of esterases (enzyme ratio = 2.93–5.84-fold), glutathione S-transferases (5.10–10.06) and monooxygenases (1.68–4.02) in resistant fields isolates were highly correlated (47.4–86.0%) with the resistant factor (RR50) determined by bioassay. All the isolates except Uttarkashi possess mutation at the 190th position in domain II of the sodium channel gene. As a mitigation strategy an Ageratum conyzoides-based characterized natural formulation was tested against all the isolates and was found effective at the concentration of 10.1–11.5%. The possibility of using the natural formulation for the management of multi-acaricide resistant ticks is discussed.
