Acaricidal Resistance in Indian Ticks against Organophosphates

The book "Acaricidal Resistance in Indian Ticks against Organophosphates" provides a comprehensive investigation of acaricide resistance in Rhipicephalus (Boophilus) microplus in India. It highlights the effects of organophosphates, particularly the acaricide Diazinon, on ticks in four Indian states: Uttar Pradesh, Punjab, Bihar, and West Bengal. The study employs various methods to determine resistance, including the adult immersion test, which uses tick mortality and oviposition rate as primary criteria. Additionally, the results of LC50, LC95, and LC99.9, as well as the discriminating dose (DD), are analyzed to assess the sensitivity status of the ticks. The investigation also includes biochemical analyses to measure acetylcholinesterase activity and explores the molecular basis of resistance through gene sequencing analyses. This research is of great significance for understanding resistance mechanisms and their implications for tick control in agriculture.
