초록

전국 8개 지역별 각 사과원에서 채집된 점박이응애(Tetranychus urticae Koch)에 대한 저항성 정도를 일본 감수성 계통과 비교한 결과 지역별 현저한 감수성 차이를 보였다. Azocyclotin, fenpropathrin, propargite 및 abamectin에 대해서는 낮거나 중간 정도의 저항성을, dicofol, fenpyroximate 및 pyridaben에 대해서는 높은 저항성을 나타내었다. 이들 계통은 한종 또는 두종 이상의 약제에 대해 감수성을 보여 특정 지역에 대해서는 적당한 살비제의 선택적 이용으로 점박이응애를 효과적으로 방제할 수 있을 것으로 사료된다.

Eight field-collected populations of the two-spotted spider mites, Tetranychus urticae (Koch) from apple orchards of different geographical areas were tested for resistance to seven acaricides by leaf disk method in comparison with a susceptible strain. Marked regional variations of susceptibility were observed. Only low to moderate resistance to azocyclotin, fenpropathrin, propargite, and abamectin was obtained. However, high resistance to dicofol, fenpyroxymate, and pyridaen by eight field-collected populations was produced. Resistance to dicofol and fenpyroxymate was widespread. All of the strains tested were susceptible to one or more o the acaricides used. These results indicate that careful selection of the chemical used against any population of the two-spotted spider mite might result in satisfactory control.
