The spraying application method according to Damiani et al. (2010b) was used. Petri dishes (90×15 mm) padded with absorbent filter paper on the inner bottom and with an extra lid of metallic mesh were used. Five adult female mites and five adult worker bees (free of mites) were placed in every modified Petri dish. Once the mites were attached at the body of the bees in each experimental unit, 1 ml of each concentration (for both botanical extracts individually) was sprayed on the bees throughout the metallic lid using a hand sprayer. A device with candy and water was placed inside each unit as food for the bees. Five bees and five mites in a modified Petri dish sprayed with alcohol 55% were included as controls. Five replicates for each experimental group were run. Bioassay dishes were placed in incubators at 28±1°C and 60% RH. Death of bees and mites was assessed at 24 and 48 h. Mortality was evaluated by gently prodding each mite with a narrow paintbrush; lack of response to consecutive stimulus over 1 min was considered an indication of death. All bees (dead or survivor bees) were visually inspected for the presence of mites.
