바퀴에 대한 dichlorvos(DDVP) 약제로 11세대 누대 도태한 계통에 대한 저항성 유발정도, 교차저항성 및 효소활성을 조사한 결과는 반수치사농도 비교시 감수성에 비하여 8.58배 증가하였고 교차정항성은 chlorpyrifos, propowur, fenvalerate 와 permethrin 약제에서 각각 3.35, 4.09, 2.83 및 2.00배의 저항성을 보였으며 효소활성은 filter paper testdptjrka수성 대비 33%가 증가하였고 전기영동시험에서는 4개의 band인 esterase-1,2,4 및 7 band 가 확인되었다.

영어 초록

The german cockroach, Blattello germanica L, populations were successively selected with dlchlowos for 11 generations. The resulting selected shin was investigated the resistance development. the cross resistance and the esterase actim@. In the dichlowos-selected(Rd) strain, the values of LCs increased 858 times more compared to the susceptible (S) strain. In the dich!o~vos-selected (Rd) strains, the cross-res~stance to chlorpyrifos, propoxur, fenvalerate and pemethnn showed 3.35. 4.09. 283 and 2.00 times. Esterase.activity of the Rd strain showed 1.33 times higher than that of the S strain in the filter paper test. In comparison of zymogram paitems of the estemse isoryme by thin agarose gel electrophoresis against the german cockroach, the S strain was separated by 4 bands uf esterase 3, 5, 6 and 8 bands and the Rd strain was separated by 6 bands of esterase 1, 2, 4, 5, 7 and 8 bands, and the resistant mechanisms of the Rd strain were considered as the 4 bands of esterase-1.2.4 and 7 bands except the common 2 bands of esterase.6 and 8 bands.
