  • Researchers collected Hyalomma anatolicum ticks from dairy farms in Haryana to assess their resistance to acaricides deltamethrin and coumaphos.
  • The study found that Charkhi Dadri tick larvae were completely susceptible, while some isolates from Hisar showed varying levels of resistance to coumaphos and deltamethrin.
  • Increased activity of certain detoxification enzymes was linked to the resistance, but no genetic mutations were detected in the genes tested, suggesting that heightened enzyme expression contributes to the ticks' resistance.
