Survival analysis of Rhipicephalus microplus larvae treated with coumarinic derivatives.

Rhipicephalus (Boophilus) microplus represents one of the greatest challenges for livestock production in tropical and subtropical regions. Its control has been based on the use of synthetic chemical acaricides, which has led to the development of resistance to active ingredients belonging to the pyrethroid and organophosphate groups. Therefore, the search for new compounds with acaricidal potential is a priority in the control of ticks in cattle.
