Abstract

Monitoring was conducted to investigate the occurrence of Grapholita dimorpha Komai in Korean apple orchards using sex pheromone traps. G. dimorpa showed four peaks per year: early May, from late June to early July, from late July to mid August, and from late August to September. After adult emergence of the over-wintered G. dimorpha, G. dimorpha catches was decreased significantly and increased again after July. In G. molesta traps, G. molesta and G. dimorpha were trapped by 98.8 and 1.2%, respectively. Conversely in G. dimorpha traps, G. dimorpha and G. molesta were trapped by 99.7 and 0.3%, respectively. The 30.6% of the moths from the damaged apple fruits were G. dimorpha. This is the first report on G. dimorpha in apple orchards in Korea.

국내 사과원에서 복숭아순나방붙이 발생여부를 조사하기 위하여 성페로몬트랩을 이용하여 조사하였다. 복숭아순나방붙이는 연간 4세대 발생을 보였으며, 월동성충 발생은 5월 상순, 제 1세대는 6월 하순~7월 상순, 2세대는 7월 하순~8월 중순, 3세대는 8월하순~9월이었다. 복숭아순나방붙이의 초기 월동성충 밀도는 높았으나 점차 감소하였다가, 7월 이후 발생밀도가 증가하였다. 성페로몬 조성성분이 비슷한 복숭아순나방과 복숭아순나방붙이 성페로몬트랩에 두 종이 혼재하여 유살되는지를 확인한 결과, 복숭아순나방 성페로몬 트랩에는 복숭아순나방이 98.8% 복숭아순나방붙이가 1.2% 유살되었으며, 복숭아순나방붙이 트랩에는 복숭아순나방붙이가 99.7%, 복숭아순나방이 0.3%로 유살되었다. 심식충류에 의해 피해를 받은 과실에서 유충을 우화하여 동정한 결과, 33.3%가 복숭아순나방붙이였다. 이상의 결과를 종합해 볼 때 복숭아순나방붙이가 사과원의 새로운 주요 과실가해 해충으로 확인되었다.
