Abstract

These studies were carried out to investigate the toxicities of 38 registered insecticides to the sweetpotato whitefly (Trialeurodes vaporariorum). Insecticide activities were evaluated by testing systemic action and residual effect in the laboratory, and control efficacy in the greenhouse. All experiments were tested at the recommended concentration(ppm) of each insecticides. Insect growth regulators (IGRs), only pyriproxyfen showed over 90% of ovicidal effect. The insecticides that showed over 90% of larvicidal activity oil 3rd nymphal instars were abamectin, acetamiprid, chlorpyrifos-methyl, imidacloprid, pyripoxyfen, and acetamiprid+ethofenprox. Insecticides with 100% adulticidal activity were abamectin, acephate, acetamiprid, benfurcarb, bifenthrin, furathiocarb, endosulfan, fenitrothion, imidacloprid, phenthoate, pymetrozine, acetamiprid + ethofenprox, ethofenprox + diazinon, furathiocarb + difluberlzuron, and triazamate+${\alpha}$-cypermethrin. Abamectin, acetamiprid, imidacloprid, pyriproxyfen, and acetamiprid + ethofenpox showed both residual effect and systemic activity. In tile control efficacy test on B. tabaci, 90% control values were obtained at 11th day after treatment of the insecticides including abamectin, acetamiprid, imidacloprid, pyripoxyfen and acetamiprid + ethofenprox. These results indicate that abamectin, acetamiprid, imidacloprid, pyriproxyfen and acetamiprid + ethofenprox can be used for tile control of B. tabaci in field.
