Acaricide resistance in Rhipicephalus (Boophilus) microplus and Hyalomma anatolicum collected from Haryana and Rajasthan states of India

Abstract

Acaricide resistance status of Rhipicephalus (Boophilus) microplus and Hyalomma anatolicum ticks against deltamethrin and diazinon was assessed in Hisar (Haryana) and its adjoining district Churu (Rajasthan) using adult immersion test (AIT) and larval packet test (LPT). The mortality slope, LC50, LC95, 95 % confidence limit and resistance factor of field ticks were determined. Results showed that R. (B.) microplus ticks collected from Tohana (Hisar) were found resistant to both the acaricides while the ticks of Agroha (Hisar) were found to be susceptible using AIT. Similar results were observed by using standard method of LPT. Again, H. anatolicum tick isolates of Tara Nagar (Churu) were found susceptible whereas Churu tick isolates were found to be resistant using AIT for both the acaricides. LPT indicated susceptible status of H. anatolicum ticks collected from Churu as well as Tara Nagar for both the acaricides. The study warrants the need for strategic use of available acaricides to overcome the development of acaricide resistance in ticks.

Assessment of acaricidal activity of nanoscale ZnO encapsulated piperine formulation against Rhipicephalus microplus

“…Acaricide resistance in arthropods is an inheritable trait [42], which is achieved by target site insensitivity to acaricides and increased metabolic detoxification by enzymes [56] such as esterases, mixed function oxidases and glutathione S‐transferases. Resistance of R. microplus towards deltamethrin was reported from different parts of India [15–18, 22]. These reports strongly coincide with the present findings on the development of acaricidal resistance in R. microplus against deltamethrin.…”

In vitro Efficacy of Deltamethrin against Hyalomma anatolicum anatolicum

“…microplus. Gaur et al, (2016) and Katuri et al, (2017) reported resistance against deltamethrin, cypermethrin, and diazinon. It is concluded from present work that deltamethrin at 75 and 100 ppm can be recommended for tick control/irradication programme.…”

An insight into the ecobiology, vector significance and control of Hyalomma ticks (Acari: Ixodidae): A review

“…Resistance to acaricides has also been reported in isolates of H. anatolicum in 20 areas of three agro climatic zones in India and these acaricides were diazinon, deltamethrin and cypermethrin (Shyma et al, 2012). The ticks, H. anatolicum, were also found resistant to deltamethrin and diazinon using adult immersion test in India (Gaur et al, 2016).…”
