“…Interestingly, the isolates were comparatively less resistant to another synthetic pyrethroid, cypermethrin. The resistance to cypermethrin was in level I-II in both adults and larvae and these results are in accordance with previous results reported by Sharma et al (2012), Chigure et al (2018) and Sagar et al (2019).…”

“…Although RR 50 of all the isolates were in the range of 1.55-3.27, the data indicate the emergence and establishment of IVM resistant tick populations in some parts of the state. Resistance against IVM has been reported from other states, viz., Punjab, Uttar Pradesh, Bihar and Madhya Pradesh (Singh et al 2015;Nandi et al 2018;Sagar et al 2019). The easy availability and applicability of the drug has resulted in excessive use of this compound without maintaining proper regimen.…”

“…The gradual establishment of organophosphate (OP) and synthetic pyrethroid (SP) resistant tick populations has increased the dependency of farmers on use of formamidine (amitraz) and macrocyclic lactones. But as in the case of OP and SP group of acaricides, with increased usage of formamidine and macrocyclic lactones, several reports of resistance have been published (Singh et al 2015(Singh et al , 2019Nandi et al 2018;Ravindran et al 2018;Sagar et al 2019).…”

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 [RR 50 ] = 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 (RR 50 ) 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.

The development of acaricide resistance in ticks infesting cattle is a major problem in the livestock industry in tropical and subtropical regions worldwide. To determine the current global trends and prevalence of acaricide resistance development (ARD) in tick populations of cattle, a systematic review and meta-analysis with an emphasis on Rhipicephalus (Boophilus) microplus was conducted. Data searches from five English electronic databases yielded 88 journal articles published between 1992 and 2020. In total, 218 in-vitro bioassays were used to investigate 3939 tick populations of cattle; of these, the 57.6% that exhibited ARD were largely limited to South America (Brazil), Central America (Mexico), and Asia (India). A total of 3391 of these tick populations were R. (B.) microplus, of which 2013 exhibited ARD. Random effects meta-analyses indicated that the exhibition of ARD was higher in R. (B.) microplus (66.2%) than in other tick species. Global prevalence estimates of ARD in R. (B.) microplus vary as a function of geography, detection methods, and acaricide compounds. In general, high heterogeneity was noted among the studies. However, homogeneity was observed among studies from India, suggesting the establishment of acaricide resistance in Indian R. (B.) microplus populations. Current tick control interventions are urgently required to limit the evolution and implications of resistance development.
