시판하고 있는 39종의 살충제에 대한 북방수염하늘소(Monochamus saltuarius)성충에 대한 약제 감수성, 침투이행성, 잔효성 및 방제효과를 조사하였다. 두가지 검정법(충체분무와 가지침지)으로 성충에 대해 100% 살충율를 보인 약제는 fenitrothion, fenthion, phenthoate, phosphamidon, dinotefuran, actamiprid, clothianidin, thiacloprid, thiamethoxam, esfenvalerate+fenitrothion, fipronil 등 11종이었으며, 방제효과가 좋은 11종에 대해 2000배, 4000 배액으로 희석된 약액을 성충에 처리한 결과 처리농도에 상관없이 모두 100% 살충효과를 보인 약제는 fenitrothion, fenthion이고 2000 배액에서만 100% 살충율를 보인 약제는 phenthoate, thiacloprid, thiamethoxam, fipronil 등 4종이었다. 뿌리 침투이행성 효과는 phosphamidon, clothianidin, thiamethoxam이 100%, thiacloprid는 77.7%의 침투이행 효과를 나타냈다. 잔효성에서는 fenitrothion, thiamethoxam은 15일째까지 80%이상, fenthion, phosphamidon, clothianidin은 10일째까지 80%이상, fenitrothion, thiamethoxam, fipronil은 처리 후 7일까지, thiacloprid는 처리 후 3일까지, fenthion, phenthoate은 처리 후 1일째까지 100% 살충율을 보였다. 방제효과에서는 11약제중 6약제(fenitrothion, fenthion, phenthoate, phosphamidon, fipronil, esfenvalerate+fenitrothion)가 처리 1일째에 그리고 3일째에는 시험약제 모두 100% 방제효과를 나타냈다.
This study was performed to investigate the toxicity of 39 registered insecticides to the susceptibility, systemic effect, and residual effect and control effect against Pine sawyer beetle, Monochamus saltuarius. Eleven kinds of chemicals such as fenitrothion, fenthion, phenthoate, phosphamidon, dinotefuran, actamiprid, clothianidin, thiacloprid, thiamethoxam, esfenvalerate+fenitrothion, and fipronil were showed 100% insecticidal activity both in body spray and twig dipping bioassay. Among these chemicals, fenitrothion and fenthion were showed 100% insecticidal activity when sprayed at 4000 times diluted solutions, and phenthoate, thiacloprid, thiamethoxam and fipronil were showed 100% insecticidal activity when sprayed at 2000 times diluted solution. Root systemic effect was showed 100% mortality in phosphamidon, clothianidin, thiamethoxam, and 77.7% in thiacloprid. In residual effect, fenitrothion and thiamethoxam were showed 80% mortality fifteen days after treatment (DAT), and fenthion, phosphamidon, clothianidin were showed 80% mortality ten DAT, fenitrothion, thiamethoxam, fipronil showed 100% mortality in seven DAT, thiacloprid was showed 100% mortality in three DAT. Fenthion and phenthoate were showed 100% mortality one DAT. In the control effect, 6 kinds of chemicals were showed 100% mortality one DAT and all chemicals showed 100% mortality three DAT.
