국내시판 살충제에 대한 미국선녀벌레의 감수성

Insecticidal activity of 31 registered insecticides was tested against Metcalfa pruinosa adults. All experiments were conducted at the recommended concentration (ppm) of each insecticide. Among them, 16 insecticides from organophosphates (dichlorvos, fenitrothion, fenthion, methidathion, phenthoate)...

Zusammenfassung:Insecticidal activity of 31 registered insecticides was tested against Metcalfa pruinosa adults. All experiments were conducted at the recommended concentration (ppm) of each insecticide. Among them, 16 insecticides from organophosphates (dichlorvos, fenitrothion, fenthion, methidathion, phenthoate), carbamates (methomyl), pyrethroids (${\alpha}$-cypemethrin, deltamethrin, fenpropathrin, ${\gamma}$-cyhalothrin), neonicotinoids (acetamiprid, clothianidin, dinotefuran, imidacloprid, thiamethoxam), and other (endosulfan) showed 100% mortality by spraying on the body of M. pruinosa adults. Dichlorvos, fenitrothion, fenthion, methidathion, phenthoate and endosulfan showed 100% mortality by plant-dipping method. The residual effect was showed 100% mortality in four insecticides (fenitrothion, fenthion, methidathion, phenthoate) at one day after treatment, and three insecticides (fenitrothion, methidathion, phenthoate) were showed the mortality of 90% at three days after treatment. 미국선녀벌레(Metcalfa pruinosa)의 방제약제를 선발하기 위하여 시판되고 있는 31종 살충제의 성충에 대한 살충 활성을 조사하였다. 모든 시험은 살충제의 추천농도(ppm)로 수행하였다. 성충에 대해 직접 분무 처리한 결과, 100%의 살충 효과를 보인 약제는 유기인계 5종(dichlorvos, fenitrothion, fenthion, methidathion, phenthoate), 카바메이트계 1종(methomyl), 합성피레스로이드계 4종(${\alpha}$-cypemethrin, deltamethrin, fenpropathrin, ${\gamma}$-cyhalothrin), 네오니코티노이드계 5종(acetamiprid, clothianidin, dinotefuran, imidacloprid, thiamethoxan), 그리고 기타 약제 1종(endosulfan) 등 총 16종이었다. 분무처리에서 100%의 살충률을 보인 약제를 대상으로 기주식물을 침지 처리하고 성충을 접종한 결과, 100%의 살충률을 보인 약제는 유기인계 5종(dichlorvos, fenitrothion, fenthion, methidathion, phenthoate)과 endosulfan 등 6종이였다. 잔효성 시험에서 유기인계인 fenitrothion, fenthion, methidathion, phenthoate은 처리 후 1일째까지 100%의 살충률 나타내었고, 약제처리 3일 후에 90% 이상의 약제는 fenitrothion, methidathion, phenthoate이었다.
