Potencial das plantas do Cerrado no controle de carrapatos Rhipicephalus microplus: uma abordagem de bioprospecção

Abstract

Objective: to investigate the use of plant extracts from plants present in the Brazilian savanna as an alternative in the control of the cattle tick Rhipicephalus microplus. Methods: the study followed the criteria of the PRISMA method, with the descriptors: "plant extracts and Rhipicephalus microplus", "acaricidal activity and plant extracts", "Rhipicephalus microplusand Brazilian savanna ", "acaricide activity" and "plant extracts" and "Rhipicephalus microplus" and "plant extracts", selecting articles between 2013 and 2023. Results: a total of 19 studies were selected to investigate the potential of Brazilian savanna plants against R. microplus. Of these, 18 showed the efficacy of these plants in the mortality of larvae and females of the tick. They indicated 57 species of Cerrado plants, belonging to 31 different botanical families, with Lauraceae being the most studied (14%). Most studies have also reported a high mortality in ticks, even with variations in extraction solvents, with ethanol being the most frequent (60.5%), mainly for extracting leaves (60.5%). The studies also prioritized evaluation in engorged females (93.5%) and, to a lesser extent, in larvae (44%). Conclusion: limited studies on Brazilian savanna plants in controlling R. microplus show potential, but research on bioactive compounds in ticks is lacking, necessitating further studies to understand their role and importance in biome conservation.
