Abstract

Thrips populations were monitored in field-cultivated pepper at Gochang, Jeonbuk province, Cheongyang, Chungnam province, and Goesan, Chungbuk province during the field growing seasons of 2017 to 2018, respectively. We classified and quantified thrips population in each plot and year. Most of the monitored thrips were composed of three species: Frankliniella intonsa, F. occidentalis, and Thrips tabaci, respectively. F. intonsa was the dominant species in all the monitoring season. The density of thrips was increased from late June in each field and year with the highest density being recorded in mid-July. Based on the results, management strategy of thrips in red peppers should be evaluated from early June with monitoring and appropriate controls.

2017년과 2018년 노지고추 재배기간인 6~8월 간 전북 고창, 충남 청양, 충북 괴산지역 노지 고추 포장에서 총채벌레의 종류와 발생현황을 조사하였다. 시기별로 총채벌레를 채집하여 동정한 결과 꽃노랑총채벌레 (Frankliniella occidentalis), 대만총채벌레(F. intonsa), 파총채벌레(Thrips tabaci)의 발생이 확인되었다. 이들 3종 중 대만총채벌레가 시기별로 가장 발생 밀도가 높은 것으로 보아 우점종으로 보여진다. 총채벌레의 발생은 6월 하순부터 증가하기 시작하여 7월 중순에 밀도가 가장 높았다. 따라서, 노지고추에서 총채벌레 방제전략은 6월 상순부터 모니터링하여 밀도증가 이전에 적절한 방제방법을 동원하여야 할 것이다.
