Characterization of deltamethrin, cypermethrin, coumaphos and ivermectin resistance in populations of Rhipicephalus microplus in India and efficacy of an antitick natural formulation prepared from Ageratum conyzoides.

Ticks and Tick-borne Diseases, 2021
Rhipicephalus microplus is posing a serious threat to productive animal husbandry. Excessive use of synthetic chemicals in tick management has led to the development of resistant tick populations.

RmKK, a tissue kallikrein inhibitor from Rhipicephalus microplus eggs

Biochemical and Biophysical Research Communications, 2014
Rhipicephalus microplus is an important ectoparasite that is responsible for transmission of anaplasmosis and babesiosis to cattle. Tissue kallikrein inhibitors might play an important role in R. microplus eggs. In the present work, we purified and characterized, a tissue kallikrein inhibitor presents in R.

Rhipicephalus (Boophilus) microplus embryo proteins as target for tick vaccine

Veterinary Immunology and Immunopathology, 2012
Rhipicephalus (Boophilus) microplus is one of the most widely distributed tick in the world. The control of the parasite is based mainly on the use of chemical acaricides, which are produced from a limited set of molecules. These drugs induce selection of acaricide-resistant ticks, and are an important source of environmental pollution.

Deltamethrin resistance in south Indian isolates of Rhipicephalus (Boophilus) microplus

Veterinary Parasitology: Regional Studies and Reports, 2016
The present communication deals with the detection and characterization of deltamethrin resistance in tick populations using biological (larval packet test), biochemical (esterase enzyme assay) and molecular assays. Ticks were collected from cattle farms of Korutla, Telangana (KOR), Mehboob Nagar, Telangana (MBN), Nagpur, Maharashtra (NAG), Parbani ...

Cattle herd shearing can help to control Rhipicephalus microplus ticks

Experimental and Applied Acarology, 2019
Given the difficulties of controlling the tick Rhipicephalus microplus due to acaricide resistance, this study aimed to ascertain whether shearing could reduce infestation in cattle. 17 taurine cattle were sheared on the anterior third of one randomly selected side. Shearing was undertaken using a machine with a blade, leaving coats with a thickness of

Microbial agents for the control of ticks Rhipicephalus microplus

Parasitology Research
Ticks are ectoparasites responsible for the transmission of various pathogens to vertebrates. They represent one of the major threats to livestock production worldwide due to their impact on the health, production and welfare of livestock destined for human consumption.

Multiple paternity in Rhipicephalus (Boophilus) microplus confirmed by microsatellite analysis

Experimental and Applied Acarology, 2009
The aim of this study was to determine if individual ticks among the progeny of a single female Rhipicephalus (Boophilus) microplus tick removed from cattle under natural conditions are the result of mating with one or several males. To this end, simulations were run using an existing dataset of genotypes from 8 microsatellite loci to predict the ...

Rhipicephalus microplus thyropin-like protein: Structural and immunologic analyzes

Veterinary Parasitology
Tick saliva has a pivotal function in parasitism. It has pharmacological and immunomodulatory properties, with several proteins reported in its composition. Thyroglobulin type-1 domain protease inhibitor (thyropin)-like proteins are found in tick saliva, but their function, properties and structures are poorly characterized.
