Abstract

The tomato leaf miner (Phthorimaea absoluta(=Tuta absoluta)) was confirmed in 16 counties in the Gyeonggi region. Its occurrence began in March, with density increasing from mid-May and peaking in early July. A sharp decline in density was observed following the transition in the cropping season. Based on field trials, two chemical pesticides were selected for larval control. Additional research is needed to optimize spraying intervals and systematic treatments for controlling tomato leaf miners.

경기지역에서 토마토뿔나방의 발생이 16시군에서 확인되었으며, 3월부터 발생이 시작되어 5월 중순부터 밀도가 증가하고 7월 상순에 최고 수준에 도달한 후, 작기 전환에 따라 밀도가 급감하는 경향을 보였다. 유충 방제용 화학농약을 선발하였으며, 효과적인 방제를 위해 살포 주기 설정과 체계처리 등 추가 연구가 필요하다.
