Abstract

Volatile oils have been extensively investigated as an alternative for tick control. This study evaluated thein vitroeffects of volatile compounds emanated byCorymbia citriodora(Hook.) K.D.Hill \& L.A.S.Johnson andEucalyptus globulusLabill., Myrtaceae, volatile oils and their major compounds, citronellal and 1,8-cineole, respectively, at doses of 10, 20, 40, 60, 80 and 100 mg/g, onRhipicephalus micropluslarvae and engorged females. The effects of these volatile oils were compared with those of commercial acaricides. In bioassays with engorged females, percentages of oviposition inhibition (OI %) and efficacy of the product (EP %) were determined, as well as tick larval mortality. The larval tests with citronellal presented high mortalities (> 80%) for all analysed doses, except 10 mg/g, while those for 1,8-cineole at the lowest dose (10 and 20 mg/g) produced the highest mortality (> 85%). In general, the volatile compounds released by these oils resulted in larval mortality and inhibition of the reproductive parameters in the engorged females, with efficacies over 80%. (AU)
