초록

같은 속의 복숭아순나방(Grapholita molesta)과 복숭아순나방붙이(G. dimorpha)는 기주범위와 야외에서의 성충 발생 양상이 유사하다. 또한 두 종은 성페로몬 성분으로 cis-8-dodecenyl acetate (Z8-12:Ac)와 trans-8-dodenceyl acetate (E8-12:Ac)을 공통으로 사용하고 있는데, 이 두 성분으로 구성된 상용 성페로몬 유인제에 두 종이 혼합되어 유인된다. 본 연구는 복숭아순나방붙이 트랩에 복숭아순나방이 혼합유인되는 현상을 줄이기 위해 성페로몬 미량성분의 효과를 분석했다. 복숭아순나방붙이 성페로몬인 Z8-12:Ac/E8-12:Ac = 85/15에 cis-8-tetradecenyl acetate(Z8-14:Ac)를 첨가했을 때, 복숭아순나방붙이의 유인은 유지되면서 복숭아순나방의 유인은 유의하게 억제되었다. Dodecyl acetate (12:Ac)와 tetradecyl acetate (14:Ac)의 첨가는 두 종의 유인력에 영향을 주지 않았다. 한편 Z8-12:Ac/E8-12:Ac/Z8-14:Ac = 85/15/10의 세 성분 성페로몬에 trans-8-tetradecenyl acetate (E8-14:Ac)를 첨가했을 때, 복숭아순나방붙이의 유인이 오히려 유의하게 억제되었다. 이상의 결과로부터 Z8-12:Ac/E8-12:Ac/Z8-14:Ac = 85/15/10의 조성이 개선된 복숭아순나방붙이의 성페로몬으로 제시되었다.

Two congener species of Grapholita molesta and G. dimorpha have similar host ranges and adult occurrence patterns. In addition, the two species commonly use cis-8-dodecenyl acetate (Z8-12:Ac) and trans-8-dodecenyl acetate (E8-12:Ac) as their major sex pheromone components. The commercial lures made of the two components, therefore, suffer a mixed attraction of these two species. This study was conducted to assess any effect of their known minor sex pheromone components to reduce the mixed attraction. When cis-8-tetradecenyl acetate (Z8-14:Ac) was added to the commercial sex pheromone consisting of Z8-12:Ac/E8-12:Ac = 85/15, the attraction to G. dimorpha was not affected, but its attraction to G. molesta was significantly reduced. However, the addition of either dodecanyl acetate (12:Ac) or tetradedecanyl acetate (14:Ac) did not influence on the attraction of both species to the commercial lure. The addition of E8-14:Ac to 3-component sex pheromone, Z8-12:Ac/E8-12:Ac/Z8-14:Ac = 85/15/10, the attraction to G. dimorpha was rather significantly suppressed. From these results, the 3-component sex pheromone, Z8-12:Ac/E8-12:Ac/Z8-14:Ac = 85/15/10 was suggested as an improved composition of sex pheromone lure for G. dimorpha.
