  • 우리나라 주요 녹차재배지에 발생하는 동백가는나방(차굴나방 전가칭. Caloptilia theivora (Walshingham))의 생활사와 발생소장을 조사한 결과는 다음과 같다. 동백가는나방은 야외 사육상 조건에서 년 6세대 경과하였는데, 난에서 우화까지의 평균기간은 봄.가을에는 32.1~38.6일, 여름에는 24.8~32.7일이었으며, 성충수명은 봄.가을에 8.4~14.5일, 여름에는 6.3~8.6일이었고 산란수는 55~71개였다. 유충의 연중 발생소장을 보면, 1992~1993년에는 5월 중순에 발생 peak를 보이기 시작하여 3~4회의 peak가 나타났으나 1994년에는 발생량이 감소하여 초기에는 뚜렷한 발생 peak가 나타나지 않다가 9월 하순~10월 초순에 발생량이 가장 많았으며, 잎에서 용태로 월동하였다. 동백가는나방의 유증기생봉으로는 Stenomesius japonicus (Ashmead). Sympiesis ringoniellae Kamijo, S. dolichogaster Ashmead와 Elasmus sp.등 4종이 채집 동정되었으며, S. dolichogaster가 우점종이다.

  • The occurrence of major pest infestation was compared between conventional tea plantation and organic tea plantation at Sulloc tea garden in Dosun-dong, Seogwipo-si, Jeju-do from 2002 to 2009. Tetranychus kanzawai was observed a lot in the second year, but it waned from late June. There was not much difference between conventional farming and organic farming in terms of pest density. Empoasca onukii was infested in the second year of organic farming compared with conventional farming, which highlighted the fact that second year of organic farming requires a special care. Scirotothrips dorsalis was highly dense in the second and third year of conventional farming, but its occurrence was lowered when the farming technique was shifted to organic farming. The number of Homona magnanima peaked 4 times each year. In 2008, the first year of organic farming, saw high occurrence of 771.2 per trap per year. In 2009, the second year, the population per trap dropped to 80, showing a great variance depending on year. The occurrence of Caloptilia theivora peaked 5 times annually. In 2008, the first year of organic farming, an average of 2,779 pests per trap was found, and in the following year, 4,143 pests were observed. It showed that density rose in organic growing period.
