Abstract

This study was performed to investigate the susceptibility and control efficacy of 27 registered insecticides against pear psylla, Cacopsylla pyricola in laboratory and field (Jincheon). Mortality of 3rd instar of C. pyricola was higher treated with pyrifluquinazon WG (97.7%), flonicamid WG (94.7%), abamectin EC (92.8%), and acetamiprid+buprofezin EC (86.8%) sprayed with field recommended concentration using a prayer in laboratory. These four insecticides also showed control effects of > 90% at 5 days after treatment in field.

국내에 꼬마배나무이(Cacopsylla pyricola)의 방제약제로 등록되어 있는 27종의 약제를 사용하여 진천지역 꼬마배나무이에 대한 실내에서의 살충활성과 야외에서의 방제효과를 조사하였다. 그 결과 3령 약충에 대한 실내 스프레이 검정에서는 abamectin EC, acetamiprid + buprofezin EC, pyrifluquinazon WG, 그리고 flonicamid WG 등 총 4종의 약제가 추천농도에서 각각 92.8, 86.8, 97.7, 94.7%의 높은 살충효과를 보였다. 살충효과가 우수한 이들 4종 약제로 야외방제효과를 조사한 결과 약제 처리 후 5일차에서 모두 90%이상의 높은 방제가를 나타내었다.
