Abstract

The populations of Riptortus pedestris (Fabricius) cause serious economic damages in local apple orchards. However, there was no study to manage its populations with environment friendly tactics. Thus, this study was conducted to analyze its attraction effects of one of R. pedestris aggregation pheromone compounds, (E)-2-hexenyl (Z)-3hexenoate (E2HZ3H), to its parasitoids, Ooencyrtus nezarae (Ishii) and Gryon japonicum (Ashmead). This compound did not increase the number of these two parasitoids and change its spatial distribution. However, this compound could attract two parasitoids within limited distance. These results indicates that one compound of R. pedestris aggregation pheromone, E2HZ3H, could be a good candidate to manage R. pedestris populations in conditions that its populations locally occurs in apple orchards.

톱다리개미허리노린재(Riptortus pedestris Fabricius)는 지역에 따라 사과에 심각한 경제적 피해를 야기하고 있지만, 사과에서 톱다리개미허리노린재 친환경 방제에 대한 연구는 전무한 실정이다. 따라서, 이번 연구에서는 톱다리개미허리노린재의 집합페로몬 성분 중 (E)-2-hexenyl (Z)-3hexenoate (E2HZ3H)이 노린재검정알벌(Gryon japonicum Ashmead)과 노린재깡충좀벌(Ooencyrtus nezarae Ishii)에 미치는 영향을 조사하였다. 사과 과수원에서 E2HZ3H는 전체 과수원에 발생하는 2종의 포식기생자의 밀도에는 직접적으로 영향을 주지 않았고 이들 포식기생자의 공간분포도 변화시키지 않았다. 그러나, E2HZ3H 루어가 설치된 지역 주변에서는 2종의 포식기생자 모두 제한적으로 유인하는 것을 확인하였다. 따라서, E2HZ3H 루어는 사과 과수원 내에서 정밀방제를 목적으로 친환경 방제에 고려될 수 있을 것으로 생각된다.
