Journal ArticleDOI
Deltamethrin and cypermethrin resistance status of Rhipicephalus (Boophilus) microplus collected from six agro-climatic regions of India.
Anil Kumar Sharma,Rinesh Kumar,Sachin Kumar,Gaurav Nagar,Nirbhay Kumar Singh,Sumer Singh Rawat,M. Dhakad,A. K. S. Rawat,D. D. Ray,Srikant Ghosh +9 more
TL;DR: A cross sectional study to assess the prevalence of synthetic pyrethroids (SP) resistance in Rhipicephalus (Boophilus) microplus in India revealed higher density of resistant ticks where intensive cross bred cattle population are reared and the SP compounds are commonly used.
Journal Article
Problem of ticks and tick-borne diseases in India with special emphasis on progress in tick control research: a review.
Srikant Ghosh,Gaurav Nagar +1 more
TL;DR: There is a need to reassess the renewed threat posed by the tick vectors and to prioritize the tick control research programme, with emphasis on acaricide resistance, tick vaccine and the development of potential phytoacaricides as an integral part of integrated tick control programme.
Journal ArticleDOI
Survey of pyrethroids resistance in Indian isolates of Rhipicephalus (Boophilus) microplus: Identification of C190A mutation in the domain II of the para-sodium channel gene
Rinesh Kumar,Gaurav Nagar,Anil Kumar Sharma,Sachin Kumar,D. D. Ray,Pallab Chaudhuri,Srikanta Ghosh +6 more
TL;DR: The occurrence of mutation in the tick isolates having high resistance factor suggested that target site insensitivity and enhanced esterase activity is the possible mechanism of resistance to deltamethrin in the Indian isolates of R. (B.) microplus.
Journal ArticleDOI
Survey of acaricides resistance status of Rhipiciphalus (Boophilus) microplus collected from selected places of Bihar, an eastern state of India.
Srikant Ghosh,Rinesh Kumar,Gaurav Nagar,Sachin Kumar,Anil Kumar Sharma,Aman Srivastava,Suman Kumar,K.G. Ajith Kumar,B. C. Saravanan +8 more
TL;DR: Four novel amino acid substitutions in AChE2 gene of field isolates and in organophosphate (OP) resistant reference IVRI-III line were identified which can possibly have a role in resistance development.
Journal ArticleDOI
Acaricide resistance in Rhipicephalus microplus collected from selected districts of Madhya Pradesh, Uttar Pradesh and Punjab states of India.

TL;DR: The isolates of Rhipicephalus microplus collected from Madhya Pradesh, Punjab and Uttar Pradesh states of India were characterized using laboratory standardized adult immersion test (AIT) against macrocyclic lactone (ivermectin), synthetic pyrethroids, organophosphates (coumaphos and diazinon) and phenylpyrazole compounds (fipronil).
