Abstract

This study was conducted to assess the occurrence and damages by thrips on greenhouse-cultivated fig in Hwaseong, Gyeonggi Province, Korea. We identified the collected species as Thrips tabaci Lindeman, Frankliniella occidentalis Pergande, and F. intonsa Trybom. The density of thrips in the greenhouses during the summer months was monitored using yellow sticky traps; T. tabaci showed the highest density, followed by F. occidentalis and F. intonsa. The damages by thrips were characterized by stunted plant growth because of delayed discoloration of the pericarp, and development of rough fruit surface. Stereomicroscopic observation on the fruit flesh revealed the growth of gray mold at the damaged area, as well as the dead bodies and exuviae of thrips. The rates of fig fruit damages per month, were 18.2%, 9.7%, 2.9%, and 1.3% in July, August, September, and October, respectively.

경기도 화성지역에서 시설재배 무화과를 대상으로 총채벌레의 발생현황과 피해특성을 조사하였다. 황색끈끈이트랩 및 피해과실에서 발생하는 총채벌레를 동정한 결과 파총채벌레(Thrips tabaci Lindeman), 꽃노랑총채벌레(Frankliniella occidentalis Pergande), 대만총채벌레(Frankliniella intonsa Trybom) 등 3종의 발생이 확인되었다. 이들 3종 중 파총채벌레의 밀도가 가장 높았으며, 다음은 꽃노랑총채벌레, 대만총채벌레 순으로 나타났다. 총채벌레에 의해 피해를 받은 과실은 비대생장과 착색이 정상적으로 이루어지지 않았고 표면이 거칠고 코르크화 되었다. 실체현미경을 이용하여 피해 받은 과실의 내부를 조사한 결과 피해부위에 회색곰팡이가 발생하였고, 총채벌레의 사체 및 탈피각이 관찰되었다. 무화과 주 수확기에 총채벌레에 의한 과실의 피해율은 7월이 18.2%로 가장 피해가 많이 나타났으며, 이후에는 8월(9.7%), 9월(2.9%), 10월(1.3%) 순으로 나타났다.
