1974년 7월부터 10월사이에 전남 곡성에 있는 개간지에서 재배되고 있는 과수 지대에서 주로 전지를 이용하여 채집된 흡수나방의 종류와 피해 상황을 조사하였는데 그 결과를 요약하면 다음과 같다. 1. 우리나라에서 이미 보고된 흡수나방은 14종인데 그 밖에 태극나방 (Speiredonia retorta Clerck), 모시나방(Cocytodes coerulea Guenee), 흰줄태극나방(Metoptarectifasciata Menetries), 애으름나방(Ophideres fullonica Linnaeus), 왕잎밤나방(Serrodes campana Guenee), 쌍띠밤나방(Mythimna turca Linne), 까마귀밤나방(Amphipyra livida Schiffermulleret Denis), 보라끝 빠른밤나방(Parallelia maturata Walker), 남방검양옷나방(Ophiusa tirhaca Cramer), 무궁화잎밤나방(Anomis mesogona Walker), .도타타밤나방(Thyas dotata Fabricius)의 11종을 새로이 기록한다. 2. 곡성 과수원에서 흡수나방의 최감기는 9월 중하순이며, 8월초 이전과 10월초부터는 나방의 수가 아주 줄어졌다. 3. 흡수나방의 비래시간과 비래수를 보면 일침후 계속 증가하다가 12시 이저네는 점점 수가 줄어지며 아침 5시 30분까지도 체재한 개체가 있었다. 4. 포도의 피해율을 보면 8월 10일 경에는 피해가 거의 없으나 8월 15일에 $1.0\%$, 9월 26일에는 $17.6\%$, 10월 4일에는 $20.3\%$였다. 5. 당도가 높아지고 산도가 낮아짐에 따라 피해 과수는 증가하였다. 단 당도 10도이하, 산도 6.2도 이상에서는 피해가 없었다.

The damage by fruit-piercing moths in orchards, primarily on grapes cultivated on reclaimed hillsides in Koksung, Cholla Namdo, was surveyed during July to October, 1974. Moths collected at night, mostly with the aid of flash light, were then classified. Results are summairzed as follows; 1. In addition to the 14 species of fruit-piercing moths reported in Korea, 11 new species were collected lot the first time ia Korea. These include. Speiredonia retorta Clerck, Cocytodes coerulea Guenee, Metopta rectifasciata Menetries, Ophideres fullonica Linnaeus, Serrodes campana Guenee, Mythimna turca Linnaeus, Amphipyra livida Schiffermuller et Denis, Paralleia maturata Walker, Ophiusa tirhaca Cramer, Anomis mesogona Walker and Thyas dotata Fabricius. 2. The maximum emergence of moths in Koksung Orchard was from the 10th to the end of September. Only a few moths were observed befroe the begining of August or after October 10. 3. The number of moths flying to grape vines increased as the time advanced from sunset to midnight. Populations gradually decreased thereafter until 5:30 a. m., when only occasional moths were observed. 4. Average damage to grape fruits by these insects was virtually nil until August 10; with subsequent infestation rates of $1.0\%$ on August 15, $17.6\%$ on September 26, and $20.3%$ on October 4, respectively. 5. Fruits of less than 10 percent sugar content and higher than 6.2 acid value were free from damage by these moths, and those of higher sugar content and lower acid value to be more heavily attacked.
