Description A study was conducted to compare the reproductive profile of deltamethrin susceptible and resistant populations of Rhipicephalus (Boophilus) microplus collected from Himalyan and sub-Himalyan regions of Uttarakhand state to assess their implications in developing control strategies. The in-vitro bioassays revealed that ticks from Kashipur were 34- times more resistant to deltamethrin; ticks from Nagla and Dehradun were more than 5-times resistant whereas ticks from Pantnagar, Almora and New Tehri had resistance factor of 4.71, 3.21 and 2.04, respectively, when compared to the susceptible tick population from Pithoragarh. The mean pre-oviposition period ranged from 3.0±0.39 (Kashipur) to 7.08±0.2 days (New Tehri). The female ticks of Nagla laid eggs for the longest period 12.17±0.42 days. No significant difference was observed in mean daily incubation period of different populations of R. microplus. The mean daily percentage hatch was higher for eggs laid on first seven days and declined thereafter. The index of egg laying was comparable for Pithoragarh (0.2262±0.001) and New Tehri (0.226±0.004) populations and lowest for Kashipur (0.206±0.005). The study revealed that reduction in susceptibility to deltamethrin did not affect the reproductive potential of the resistant population of ticks. Thus number of applications along with the correct dosage of the drug is important in formulating management strategies against ticks.
