단감원에서 복숭아명나방의 발생양상과 수확기 단감의 피해과율

초록

수은유아등과 성페로몬트랩을 이용하여 2000년과 2001년에 남부지방의 단감원에서 복숭아명나방의 발생양상을 조사하고 수확시기의 과실에 대한 피해정도를 1999년부터 2001년까지 조사하였다. 복숭아명나방은 년 3회의 발생피크를 나타내었는데, 제1화기는 6월 중하순, 2화기는 8월 중하순, 3화기는 9월 하순이 발생최성기이었다. 집중방제 과원에서는 방제소흘 과원보다 복숭아명나방이 적게 발생하였다. 조사대상 과수원에서 수확시기의 과실에는 복숭아명나방 유충에 의한 피해과를 발견할 수 없었다. 따라서 이들 두 검역해충이 수출용 단감에 존재할 가능성은 아주 낮다고 할 수 있다. 한편 단감원 주변의 식생과 수확기 과실의 피해율(0%)로 볼 때, 유아등이나 성페로몬트랩에 유인된 복숭아명나방은 주변의 밤나무로부터 이끌려온 것일 가능성이 크다.

Seasonal Occurrence Pattern of Peach Pyralid Moth, Dichocrosis punctiferalis, in Fuyu Persimmon Orchards and Fruit Damage at Harvesting Time

Abstract

Seasonal occurrence pattern of the peach pyramid moth (PPM), Dichocrosis punctfferahs, was studied by sex pheromone traps and mercury light traps in several Fuyu persimmon orchards under different control pressures in southern region of Korea in 2000 and 2001. Fruit damage by the larvae was also checked at harvesting time from 1999 to 2001. The pattern showed 3 distinct peaks, the 1st one in mid to late June, the 2nd one in mid to late August, and the 3rd one in late September. Number of PPM catches was higher in less controlled than in intensively controlled orchards. There were no persimmon fruits damaged by the larvae of PPM and persimmon fruit moth, Stathmopoda masinissa, in our samples from the testing orchards at harvesting time. Therefore, it is unlikely that these two quarantine pests are included in the exporting fruits. Considering flora adjacent to the tested orchards and zero levels of fruit damage by the larvae, there is a strong possibility that the moths flew from neighbouring chestnut trees or other host plants to be attracted to the traps in the persimmon orchards.
