Bovine genetic resistance effects on biological traits of Rhipicephalus (Boophilus) microplus

open access: yesVeterinary Parasitology, 2015
This study aimed to verify the influence of bovine genetic resistance on biological traits of the Rhipicephalus (Boophilus) microplus tick. Genetic resistance or susceptibility was determined according to breeding values for tick counts, predicted using a dataset of 9007 Hereford and Braford (Hereford×Zebu) bovines naturally infested and raised under ...

Phytochemical analysis and acaricidal activity of Aloe arborescens Mill. extracts against Rhipicephalus (Boophilus) microplus

open access: yesSemina: Ciências Agrárias, 2017
The indiscriminate use of chemical acaricides has allowed Rhipicephalus (Boophilus) microplus to develop resistance to several active principles. However, botanical extracts have been tested as an alternative method to control those ticks.

Repellent Effects of Encapsulated Carvacrol on the Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)

open access: yesJournal of Medical Entomology, 2019
Rhipicephalus (Boophilus) microplus (Canestrini) is a problem for livestock production systems, and its control has become challenging due to the selection of tick populations resistant to synthetic chemical acaricides. The use of repellent compounds prevents contact between the arthropod parasite and the host and can, thus, contribute to increases in ...
