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.
