The biocidal activity of castor oil plant (Ricinuscommunis) in controlling the whitefly Bemisiatabaci (Genn) (Homoptera: Aleyrpdidae) was examined. Castor oil was extracted from seeds using different solvents, hexane, acetonitril and methanol.Assays were performed with adults and larvae. Mortality of the pest increased with increasing concentrations of castor oil. The lethal concentrations of the castor oil extracts was higher for adult fly than the immature stage. The insecticidal values of castor oils were compared with other formulations based on Azadirachtin (neemix, 4.5% EC) and Pyrethrum 5% SC. Emulsions of castor seed oil gave effective control against the whitefly Bemisiatabaci (Genn).
