Abstract

Endotherapy is a tactic for phytosanitary products application to trees and palm. The goal of this study was to verify the efficiency of trunk injections in cashew trees to control of whitefly (Aleurodicus cocois) (Curtis, 1846) (Hemiptera: Aleyrodidae). To test this technology were used 17 cashew trees with one trunk or more. The injections were applied in just one trunk in plants with two or more trunks. Two doses of acephate were tested. For each centimeter of trunk diameter were applied 5.4 g or 0.25 g of active ingredient. Immediately before the application of the insecticide and at 1, 6, 9 and 16 months later, 12 mature leaves per plant were collected in the median part of the cashew canopy to count the number of adult whiteflies. There was no significant difference in the number of A. cocois over the months after the insecticide trunk injection in plants with a single trunk. Injections with acephate in cashew tree trunk are effective on whitefly control.
