Abstract

The diamondback moth, Plutella xylostella, overwinters in some protected areas in Korea. Using a sex pheromone trap, the adults were monitored since the occurrence of the overwintering populations. In Andong, P. xylostella exhibited four adult peaks in a year. Biological characters, such as cold tolerance, insecticide susceptibility, and developmental rate, were analyzed and showed a significant variation among different local overwintering populations. Population genetic variation was assessed with molecular markers, in which the initial high genetic variation among the overwintering populations decreased with the progress of seasons. These results suggests that there may be a significant migration of P. xylostella to decrease the genetic variation among the different local populations that are different in biological characters.

배추좀나방(Plutella xylostella)은 시설재배지를 중심으로 국내 자연 상태에서 월동한다. 안동지역에서 이른 봄부터 배추좀나방 성페로몬트랩을 이용하여 배추좀나방의 성충 발생 시기를 주기적으로 조사한 결과 연중 4 회의 성충 발생 피크를 보였다. 월동 집단을 대상으로 서로 다른 지역 집단 간 생물적 특성을 조사한 결과 내한성, 약제감수성 및 발육속도에서 뚜렷한 집단 특성을 나타냈다. 분자마커로 집단변이를 분석한 결과 월동세대의 높은 집단변이는 계절이 진행됨에 따라 낮아지는 양상을 나타냈다. 이 결과는 배추좀나방의 국내 월동 집단 사이의 생물적 특성 차이를 나타냈고, 이들의 높은 유전적 분화는 계절이 진행됨에 따라 감소하여 이들 집단 사이의 개체들의 이동에 따른 유전적 교환이 이뤄졌다는 것을 제시했다.
