abstract
The acaricidal and repellent activity of three ethanolic extracts of two plant species on Raoiella indica was evaluated under laboratory conditions. The ethanolic extract of Plectranthus amboinicus caused the highest repellence of 61% over R. indica at 96 hours of evaluation, being statistically superior to the other extracts. Extracts of leaves and seeds of Brosimum alicastrum caused maximum 24% repellency. It was also observed that three extracts can not be considered as potential acaricides, due to the low mortality that they caused on R. indica.
