사과원에서 (E)-2-hexenyl (Z)-3hexenoate 성분이 노린재깡충좀벌(Ooencyrtus nezarae)(Hymenoptera: Encyrtidae)과 노린재기생알벌(Gryon japonicum) (Hymenoptera: Scelionidae) 발생에 미치는 영향

초록

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.
