Abstract

Adoxophyes spp. are the major rests of a pear. The larvae attack both leaves and fruits. (Z)-9-tetradecenyl acetate (Z9-14:Ac), (Z)-11-tetradecenyl acetate (Z11-14:Ac), (E)-11-tetradecenyl acetate (E11-14:Ac) and 10-methyldodecyl acetate (10me-12:Ac) have been reported as the sex pheromone components of the genus Adoxophyes. Our objective was to determine the difference in sex pheromone composition of three different A. spp. populations each from Cheonan, Sangju, and Naju area orchards in Korea. Gas chromatography (GC) analyses of pheromone gland extracts of virgin females confirmed the presence of two compounds (Z9-14:Ac and Z11-14:Ac) in Cheonan and Sangju populations, and four compounds (Z9-14:Ac, Z11-14:Ac, E11-14:Ac and tome-12:Ac) in Naju population. The Z9-14:Ac and Z11-14:Ac were detected in the ratio of 80:20 in the Cheonan population and 3:97 in the Sangju population. Females of Naju population produced sex pheromone blend consisting of Z9-14:Ac, Z11-14:Ac, E11-14:Ac and 10me-12:Ac at a ratio of 31:62:6:1. Field trapping tests in pear orchards with Z9-14:Ac and Z11-14:Ac indicated that maximum captures of the male were obtained with traps baited by 80:20 in Cheonan, 10:90 in Sangju, and 30:70 in Naju. These results suggest that there are remarkable geographical variations in the sex pheromone composition of A. spp. in pear orchards in Korea, and taxonomic classification of these species must be carefully assessed.

애모무늬잎말이나방은 배의 주요 해충으로서 유충이 잎과 과실을 가해한다. Adoxophyes 속의 성페로몬은 4가지 성분(Z9-14:Ac, Z11-14:Ac, E11-14:Ac, 10me-12:Ac)이 보고되어 있다. 본 연구는 3개 지역(천안, 상주, 나주)의 배 과원에서 발생하고 있는 개체군들 간에 성페로몬 조성의 차이를 구명하기 위해 실시하였다. 처녀 암컷의 성페로몬 샘에서 추출한 물질을 GC로 분석한 결과, 천안과 상주개체군에서는 2가지 성분(Z9-14:Ac와 Z11-14:Ac)이 검출된 반면, 나주 개체군의 경우에는 4가지 성분이 모두 검출되었다. 천안 개체군에서는 Z9-14:Ac와 Z11-14:Ac가 80 : 20의 비율로 검출되었으나 상주개체군에서는 3 :97의 비율로 검출되었다. 한편 나주 개체군의 경우에는 Z9-14:Ac, Z11-14:Ac, E11-14:Ac, 10me-12:Ac가 31:62:6:1의 비율로 검출되었다. 야외에서 Z9-14:Ac와 Z11-14:Ac의 혼합비율을 달리한 트랩에 유인된 수컷 수를 조사한 결과, 천안, 상주, 나주 지역의 배 과원에서 가장 효과적인 성분조성은 각각 80:20, 10:90, 30:70이었다. 이러한 결과들은 배 과원에서 발생하고 있는 애모무늬잎말이나방의 성페로몬 조성이 지역에 따라 상당한 변이가 존재하는 것으로 보아 이들 개체군간의 분류학적 위치에 대한 면밀한 검토가 필요함을 보여주고 있다.
