Abstract

친환경 시설재배 시금치에서 생장점 부위를 가해하는 응애를 채집하여 곤봉가루응해(Tyrophagus similis Volgin, 1949)로 동정되었다 곤봉가루응애에 의한 시금치의 피해는 주로 생장점부근의 어린잎에서 나타나는데 곤봉가루응애의 크기가 0.5 nm 정도로 매우 작아 농민들이 육안으로 해충을 확인하기는 매우 어렵다. 본 연구에서는 우리나라에서 처음으로 확인된 곤봉가루응애에 의한 시금치 피해에 대해 보고하고 응애의 형태 및 피해증상에 대한 정보를 제공하고자 한다. A mite damage was observed in spinach (Spinacia oleracea L.) under organic culture greenhouses. The mite was identified as Tyrophagus similis Volgin, 1949. It was very difficult for the farmers to diagnose the mite damage because of its tiny size about 0.5 nm in length. And the symptom was not clear at the early growth stage of the spinach because the mite mainly attack the very young leaves. In this study, we first report the spinach damages by T. similis in Korea. Informations on the mite morphology and the spinach damage symptoms are provided for the diagnosis.
