摘要
二化螟(Chilo suppressalis (Walker))又名為蛀心蟲或稻條螟，在台灣北部及中部無論第一期或第二期稻均可遭受其幼蟲危害導致枯心與白穗。性費洛蒙為二化螟綜合防治之重要資材，可以應用於雄蟲誘殺及蟲害密度監控。本文探討微膠囊緩釋膏劑與傳統塑膠管誘引成效。分別在103年與104年於彰化大村與雲林土庫水稻田進行二化螟性費洛蒙田間誘引活性試驗。以塑膠管及高劑兩種二化螟性費洛蒙劑型配搭翼型黏膠式誘蟲盒所誘捕之蟲隻數目以T檢定進行誘引成效之統計分析與比較。試驗結果顯示膠囊緩釋膏劑可展現與現有塑膠管相同甚至更優之誘引成效，且降低二化螟性費洛蒙劑量致原有劑量之一半並不會明顯影響誘引效果。本實驗結果可提供做為開發新型二化螟蟲害防治資材之依據。
並列摘要
Striped rice stem borer (Chilo suppressalis (walker)) is a wild-spread pest in Asia. The stem borer larvae would cause “dead hearts” and “white heads” symptom in cropping paddy during both the first and the second periods of cultivation in Taiwan. Sex pheromone is one of the major materials for the pest control of Chilo suppressalis, which can be applied to male trap-to-kill and density monitoring strategies. The effectiveness of attraction is evaluated by the number of male stem borer attracted by the sex pheromone integrated with the wing sticky trap. The statistical results are analyzed by T-test. The micro-encapsulized formulation, demonstrated the control-releasing effect, showed similar or better attraction effect when compared to that of the plastic tube formulation. Reducing the dose of the active components to half of its original dose does not significantly affect the attracting effect. The experimental results can be provided as the basis for developing of new types of pest control materials for striped rice stem borer .
