2010년부터 2011년까지 미얀마 예진 지역의 과수원에서 methyl eugenol trap을 이용하여 과수원 해충인 과실파리에 대한 발생빈도와 피해정도에 대한 연구를 수행하였다. 망고, 구아바, 대추나무를 대상으로 과실파리의 발생 정도를 알아보고 아울러 강수량, 온도, 습도, 일조시간 등 발생과 기후적요인과의 상호관계 등을 분석하였다. 그 결과 회귀분석에서 강수, 최저온도 그리고 상대습도는 과실파리의 발생에 긍정적인 영 향을 주었고 반면에 일조량은 발생을 억제하는 요인으로 작용하였다. 그리고 Bactrocera arecae, B. carambolae, B. correcta, B. dorsalis, B. kandiensis, B. latilineola, B. malaysiensis, B. neocognata, B. raiensis, B. verbascifoliae와 Carpomya vesuvina 등, 모두 11종의 과실파리가 조사되 었고, 그 중 B. correcta와 B. dorsalis가 29.3%와 28.6%로 많은 개체수를 나타내었다. 구아바가 가장 피해가 심했고(59±15.4), 다음은 망고였으 며(35.5±12.1), 반면에 대추에서 가장 낮은 비율을 보였다(18.5±7.9).

Population of fruit flies was monitored by using methyl eugenol trap during 2010-2011 in Yezin, Myanmar. Population numbers were analyzed with meteorological factors including rainfall, temperature, relative humidity and duration of sunshine. Samples of mango, guava, and jujube fruits were collected from orchards. The fruits were kept in containers so that the species of flies infesting the fruit could be identified when the adult insects emerged and to assess damage caused by fruit flies. Regression analyses indicated that populations of fruit flies were observed to be positively correlative with rainfall, minimum temperature and relative humidity, and negatively correlative with the duration of sunshine. Eleven species of fruit flies, Bactrocera arecae, B. carambolae, B. correcta, B. dorsalis, B. kandiensis, B. latilineola, B. malaysiensis, B. neocognata, B. raiensis, B. verbascifoliae, and Carpomya vesuvina, were identified. B. correcta and B. dorsalis were the most abundant and accounted for 29.3% and 28.6% of total emerged adults in the different fruit samples. The highest percentage of fruit damage was observed on guava (59±15.4), followed by mango (35.5±12.1) while the lowest was recorded on jujube (18.5±7.9).
