Abstract

The changes in major moth populations were monitored by sex pheromone traps in pear orchards at Yuseong-Gu, Daejeon from 2008 to 2010. Among four major moths, Grapholita molesta and Caposina sasakii occurred most frequently. Their occurrences peaked 2 to 3 times during the growing season from May to September. G. molesta was exceptional, occurring until September. For the environmentally-friendly control of these moths, 9 control materials including insect pathogenic bacteria and environmentally-friendly agricultural materials, were examined on the larva of 4 kinds of moth and sprayed on pear leaves in the field. As the generalized results of bioassay, Bacillus thuringiensis subsp. kurstaki and Sophora flavescens extract were shown to have better control effects than any other control material.
