Phenotypic and genotypic characterization of acaricide resistance in Rhipicephalus microplus field isolates from South Africa and Brazil [PDF]

International Journal for Parasitology: Drugs and Drug Resistance
Rhipicephalus (Boophilus) microplus is one of the most successful ticks infesting cattle around the world. This highly-invasive species transmits cattle parasites that cause cattle fever leading to a high socio-economic burden.

Effect of essential oils against acaricide‐susceptible and acaricide-resistant Rhipicephalus ticks [PDF]

Experimental and Applied Acarology, 2021
The indiscriminate use of acaricides is a problem worldwide and has increased the selection of acaricide-resistant tick populations. The goal of this study was to evaluate the acaricide effects of two essential oils (from Schinus molle and Bulnesia ...

Acaricide resistance in livestock ticks infesting cattle in Africa: Current status and potential mitigation strategies [PDF]

Current Research in Parasitology and Vector-Borne Diseases, 2022
In many African countries, tick control has recently been the responsibility of resource-poor farmers rather than central government veterinary departments. This has led to an increase in acaricide resistance, threatening the welfare of livestock farmers

Evolutionary Aspects of Acaricide-Resistance Development in Spider Mites [PDF]

Psyche: A Journal of Entomology, 2009
Although the development of acaricide resistance in spider mites is a long-standing issue in agricultural fields, recent problems with acaricide resistance may be characterized by the development of complex- and/or multiresistance to acaricides in ...

Knowledge, attitude and practices study of acaricide usage and tick control in South Omo Zone pastoral areas, South-Western Ethiopia

Heliyon, 2023
Although acaricide chemotherapy is widely used to control tick infestation in Ethiopia, its effectiveness is uncertain due to misusage by herdsmen. Currently, there is no study being conducted in the South Omo Zone of Ethiopia which shows the knowledge ...

Cost-Effectiveness of Acaricide Application Methods against Heartwater Disease in South Africa

Agriculture, 2023
In an economic sense, heartwater disease is the most important tick-borne disease faced by South African livestock farmers. Methods to control the disease vary among farmers, and the preferred method depends on the prevalence of the disease in a specific

Widespread acaricide resistance and multi-resistance in Rhipicephalus microplus in Ecuador and associated environmental and management risk factors

Ticks and Tick-Borne Diseases, 2023
Rhipicephalus microplus is a cattle tick widely distributed in tropical and subtropical areas. Various acaricides are used and applied to control the ticks, but resistance is common.

Relationship between acaricide resistance and acetylcholinesterase gene polymorphisms in the cattle tick Rhipicephalus microplus

Parasite
In this study, we aimed to develop a comprehensive methodology for identifying amino acid polymorphisms in acetylcholinesterase transcript 2 (AChE2) in acaricide-resistant Rhipicephalus microplus ticks.

Genomic assessment of targets implicated in Rhipicephalus microplus acaricide resistance.

PLoS ONE
Globally, the prevalence of Rhipicephalus microplus resistance to various acaricides has increased, and there is a need for the identification of molecular markers that can predict phenotypic resistance.
