| dc.description.abstract | The current study was conducted to determine the epidemiology of ixodid ticks in cattle along with assessment of associated risk factors in Mid hill zone of Himachal Pradesh. The study was conducted from October, 2020 to September, 2021. A total of 749 animals were screened for tick infestation from five districts of Himachal Pradesh viz.Kullu, Mandi, Shimla, Kangra and Chamba. The overall tick prevalence rate was recorded to be 68.62%. Three species of ticks were recorded viz. Rhipicephalus (Boophilus) microplus, R. (B.) annulatus and Hyalomma anatolicum anatolicum with the prevalence rate of 64.56, 32.91 and 2.53%, respectively. Ticks were most prevalent in rainy season (76.2%) followed by summer (65.1%) and in winter season (63.9%) (P1 year of age group (78.9%), followed by >6months-1 year age (44.1%) and least in young animals (25.6%) (P0.05) when the acaricidal application was done both on body of animals and shed after period of every three months. In order to determine the resistance against synthetic pyrethroids viz. deltamethrin and cypermethrin in R. (B.) microplus, in vitro Larval Packet Test bioassay was performed. The results revealed that R. (B.) microplus field isolates collected from districts Kangra and Kullu were found to be having level I resistance whereas isolates collected from districts Mandi, Shimla and Chamba were having level II resistance against deltamethrin. Rhipicephalus (Boophilus) microplus was found to be susceptible against cypermethrin in all the five districts of mid hill zone of Himachal Pradesh. | en_US |
