국내등록사용중인 살충제에 대한 온실가루이의 감수성

Susceptibility of greenhouse whitefly, Trialeurodes vaporariorum (Homoptera: Aleyrodidae) against commercially registered insecticides in Korea

본 연구에서는 시판되고 있는 38종의 살충제에 대한 온실가루이 (Trialeurodes vaporariorum)의 발육단계별 감수성을 조사하고, 침투이행성, 잔효성 및 방제효과를 평가하였다. 모든 시험은 살충제의 추천농도로 수행하였다. 알에 대해서는 IGR계인 pyriproxyfen만이 90%이상의 부화억제효과를 나타내었다. 3령약충에 대해서는 abamectin, acetamiprid, chlorpyrifos-methyl, imidacloprid, pyripoxyfan, acetamiprid+ethofenprox가 90%이상의 살충효과를 나타내었다. 그리고 성충에 대해서는 유기인계의 acephate, fenitrothion, phenthoate, 카바메이트계의 berfurcarb, furathiocarb, 피레스로이드계의 bifenthrin, 네오니코티노이드계의 acetamiprid, imidacloprid, 혼합제의 acetamiprid+ ethofenpox, ethofenprox+ diazinon, furathiocarb+ diflubenzuron, triazamate+${\alpha}$-cypermethrin 기타 abamectin, endosulfan, pymetrozine 등이 100%의 살충율을 나타내었다. Abamectin, acetamiprid, imidacloprid, pyriproxyfen, acetamiprid+ethofenprox는 성충에 대해서 잔효성뿐만아니라 침투이행효과도 나타내었다. 방제효과시험에서 abamectin, acetamiprid, imidacloprid, pyriproxyfen, acetamiprid+ethofenprox은 처리후 11일째부터 90%이상의 방제효과를 나타내었다.

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.
