Combination of the Entomopathogenic Fungus Beauveria Bassiana and the Plant Compound Eugenol Against the Rhipicephalus Microplus Tick: Mortality, Morphological Alterations and Ovarian Lipid Profile

Entomopathogenic fungi and eugenol have demonstrated great potential against ticks, particularly cattle tick Rhipicephalus microplus. In a pioneering study, Beauveria bassiana sensu lato (s.l.) CG 479 and eugenol were combined to assess their impact on the lipid profile and ovarian morphology of R. microplus. Germination tests revealed that regardless of concentration, the combination of B. bassiana s.l. at 1 × 106 conidia ml-1 with eugenol at 0.18 mg ml-1 or 0.75 mg ml-1 exceeded 98
