바퀴(Blattella germanica L.)를 chlorpyrifos와 permthrin 살충제로 누대도태하여 얻어진 저항성 바퀴를 대상으로 저항성 유발 및 교차저항성에 대해서 조사한 결과는 다음과 같다. chlorpyrifos와 permethrin으로 6세대 도태 한 결과 감수성 계통 보다 도태계통의 반수치사농도가 각각 3.23배, 2.10배 증가하였다. chlorpyrifos도태계통에 있어서 propoxur, fenvalerate 및 permethrin의 반수치사농도가 각각 2.97배, 3.89배 및 1.31배로써 fenvalerate 와 proposur가 permethrin보다 비교적 높은 교차저항성을 보였으며, permethrin 도태계통에 있어서 chorpyrifos, propoxur 및 fenvalerate의 반수치사농도가 각각 1.42배, 1.08배 및 5.23배로써 fenvalerate가 다른 살충제에 비하여 비교적 높은 교차저항성을 보였다.

The German cockroach (Blattella germanical L.) populations were successively selected with chlorpyrifos and permethrin for xis generations. The resulting resistant strains, $R_{chlorpyrifos}$(Rc) and $R_{permethrin}$(Rp) were observed resistant development and the cross-resistance. The result indicated that the values of $LC_{50}$ were increased 3.32 and 2.10 times from the susceptible strain, respectively. In the Rc strains, the values of the $LC_{50}$ of fenvalerate, propoxur, permethrin were to 3.89, 2.97, and 1.31 times higher than that of the suseptible, respectively. In the Rp strains, the values of the $LC_{50}$ of fenvalerate, chlorpyrifos, and propoxur showed 5.23, 1.42, and 1.80 times cross-resistance.
