Abstract

This study investigated the efficiency of mating disrupters for the control of Grapholita molesta(Busck) and Adoxophyes orana in pear orchards. G. molesta was shown 4 peak occurrence, which were different according to treatments. In conventional control, many moths were captured in mid and late April and peaks occurred in mid June, August, and early-mid September. In the non-control treatment, there were low populations in April. A. orana also appeared to 4 peak in 2007. Moths were rarely captured in mating disrupter treatment but many were captured in both the non-control and in conventional treatment. A. orana damage differed significantly between mating disrupter use and conventional control in 2006. Especially, the difference was significant between conventional control and mating disrupter to leaf damage in August, and there were similar results in the damage by G. molesta in the shoots and fruits.

본 연구는 배 과원에서 과실과 신초 등에 피해를 주는 복숭아순나방과 사과애모무늬잎말이나방에 대한 교미교란제의 효과를 검토하기 위해 수행하였다. 2007년에 복숭아순나방은 4회의 발생 peak를 보였으나 처리에 따라 약간 다르게 나타났다. 관행방제의 경우 4월 중 하순에 가장 많은 수가 포획되었고, 6월 중순, 8월 중순, 9월 상.중순에 각각 발생 peak를 보였으나 무방제구의 경우, 4월 발생량은 미미하였다. 사과애모무늬잎말이나방도 4회의 발생 peak를 보였다. 교미교란제 처리구에서는 예찰트랩으로 거의 포획되지 않았고, 무방제구와 관행방제구에서는 유사하게 포획되었다. 배 과원 나방류의 피해는 2006년의 경우, 사과애모무늬잎말이나방에 대한 교미교란제 처리구와 관행방제구간에는 유의성이 있었으며, 특히 교미교란제처리구에 살충제 처리내용에 따라 8월의 피해엽율간에는 유의성이 달랐고, 복숭아순나방에 의한 신초와 수확한 과실에서도 유사한 결과를 보였다.
