본 연구는 율무 주산단지인 경기도 북부의 연천 지역에서 율무에 크게 피해를 주는 조명나방에 대한 발생 생태 조사 및 방제적기에 관한 연구를 수행한 결과는 다음과 같다. 율무 조명나방은 연천지역에서 성충 발생은 년간
This study was carried out to select the effective insecticides for control of Ostrinia furnacalis(Guenee) in Yonchon, northern part of Kyunggi province, where is main producing region of adlay in Korea. The Asian corn borer in adlay field had three generations a year. The first stage of adult activity was higher from late May to middle June, the second from late July to early August and the third late September. Based on difference in control value, the relative ranks of some insecticides were lambda cyhalothrin EC > cartap hydrochloride GR > carbaryl EC. In control value by different application timing of Lambda cyhalothrin EC, yields were significantly different, that is, twice applications on second generation showed the control value of
