Abstract

The blueberry gall midge, Dasineura oxycoccana (Diptera: Cecidomyiidae), has known as a key pest of blueberries in the southeastern United States, Europe and Canada. It can cause considerable damage to developing flower buds and also injure vegetative growth by distorting and blackening shoot tips on blueberries. In 2010, same damage symptoms were observed on blueberries, Vaccinium spp., in Hwaseong-si, Gyeonggi-do. And, D. oxycoccana was identified from the farms and it was designated as a quarantine pest in Korea. The occurrences of D. oxycoccana and its damages were investigated in the blueberry greenhouse in 2011. Nationwide survey revealed that most of the blueberry greenhouses were infected by D. oxycoccana. An environment-friendly management method for D. oxycoccana was developed by changing soil environment in the blueberry greenhouse.

Dasineura oxycoccana는 미국, 캐나다, 유럽 등에 분포하는 해충으로, 블루베리에 발생할 경우 신초와 꽃눈을 가해하여 막대한 피해를 유발하는 주요 문제 해충이다. 국내에서는 2010년 경기도 화성시 블루베리 재배지에서 유사증상이 발견되어 피해조사 및 정밀동정을 실시한 결과 D. oxycoccana에 의한 피해로 확인되어 블루베리혹파리로 명명하였고 검역관리해충으로 지정되었다. 2011년 전국적인 조사 결과 대부분 블루베리 재배지역에서 블루베리혹파리 발생 및 피해가 확인되었다. 시설 비가림 재배 농가에서 건조한 펄라이트나 친환경 부산물인 왕겨 등을 이용하여 블루베리혹파리 유충 및 번데기 증식에 불리한 물리적 환경조건을 조성함으로써 블루베리혹파리 발생 및 그에 의한 신초 피해를 감소시킬 수 있어서 블루베리혹파리의 친환경 방제 수단으로 활용 가치가 높았다.
