Whiteflies are pests of many crops. They cause severe yield losses and reduce crop quality on fruits. Insecticides of differents modes of action have been used with little success in the control of this pest. In this work, the efficiency of buprofezin and pyriproxyfen applied alone and/or mixtured with fenpropathrin and acephate on Bemisia tabaci B biotype eggs, nymphs and adults was evaluated under field conditions. The experiment was conduced in a randomized complete block design in an irrigated area in Paraipaba, CE, Brazil, with six treatments and eight replicates. The mixture of the insecticides fenpropathrin + acephate applied weekly alone or mixtured wasefficient to control eggs, nymphs and adults of the whitefly, while the insect growth regulators buprofezin and pyriproxyfen did not control eggs and adults, but they controled nymphs, being pyriproxyfen more efficient than buprofezin.
