갈색여치(Paratlanticus ussuriensis)의 방제약제를 선발하는 목적으로 시판되고 있는 33종의 살충제의 종령약충과 성충에 대한 살충활성을 조사하였다. 모든 시험은 살충제의 추천농도(ppm)로 수행하였다. 종령약충과 성충에 대해 유기인계인 acephate, chlorpyrifos, diazinon, EPN, fenitrothion과 혼합제인 chlorpyrifos+${alpha}$-cypemethrin이 처리방법에 관계없이 100%의 살충률을 나타내었다. 그러나 페닐피라졸계인 fipronil은 엽침지법에서만 100%의 살충률을 나타내었다. 카바메이트계인 benfuracarb와 furathiocarb는 80%이상의 활성을 나타내었다. 혼합제인 etofenprox+diazinon, esfenvalerate+fenitrothion은 종령약충에 $60{sim}80%$의 살충활성을 나타내었다. 잔효성실험에서 acephate, chlorpyrifos, diazinon, EPN, fenitrothion 약제처리 후 1일째까지는 100%의 살충율을 나타내었으나, 그 이후는 효과가 없었다.
Insecticidal activity of 33 registered insecticides was tested against last nymphal instars and adults of ussur brown katydid (Paratlanticus ussuriensis). All experiments were tested at the recommended concentration of each insecticides by producer. Acephate, chlorpyrifos, diazinon, EPN and fenitrothion which were organophates, and a mixture combined with chlorpyrifos+${alpha}$-cypemethrin showed 100% mortality of P. ussuriensis. But fipronil showed only 100% mortality in leaf-dipping method. Carbamates insecticidal groups, benfuracarb and furathiocarb were showed over 80% and phenthoate was $60{sim}80%$ in mortality of P. ussuriensis. Among the mixture, etofenprox+diazinon and esfenvalerate+fenitrothion were showed 60-80% against last nymphal instars of P. ussuriensis. Otherwise, acephate, chlorpyrifos, diazinon, EPN and fenitrothion were showed 100% mortality of P. ussuriensis within only 24 hours after treatment, but there was no effective after then in residual tests with leaves.
