Abstract

Methyl (E,E,Z)-2,4,6-decatrienoate is the aggregation pheromone of brown-winged stink bug Plautia stali (Hemiptera: Pentatomidae). Attractiveness of the pheromone synthesized in Korea was compared with that of synthesized in Japan in the field. A lure filled with hexane was used as a control treatment. Catches in trap baited with Korean pheromone was significantly higher than that baited with Japanese one only in one orchard out of three sweet persimmon orchards in 2008. However there was no difference in trap catches between Korean and Japanese pheromones at three sites in 2009. Gas chromatography analysis showed that the components of both pheromones were not different each other. Monitoring of P. stali seasonal fluctuation using Korean pheromone showed that the bugs were most captured in August, 2008 and in September, 2009.

갈색날개노린재의 집합페로몬은 methyl (E,E,Z)-2,4,6-decatrienoate이다. 야외에서 우리나라에서 합성된 집합페로몬의 유인력을 일본산과 비교하였다. 2008년에는 유인력을 조사한 3개의 단감 과원 중에서 한 곳에서만 국산 페로몬에 더 많은 수가 유인되었다. 그러나 2009년에는 국산과 일본산 페로몬의 유인력 차이는 없었다. 국산과 일본산 집합페로몬을 GC분석 한 결과 두 페로몬의 성분에는 차이가 없었다. 국산페로몬으로 갈색날개노린재의 발생 시기를 조사한 결과, 2년 동안 모두 뚜렷한 발생 경향이 없었으며, 2008년에는 8월에, 2009년에는 9월에 가장 많이 유인되었다.
