中文摘要 | 利用雙選 I 形管生物活性測定法(長 250 cm× 直徑 30 cm )檢測 Solanum viarum 葉片萃取物對番茄夜蛾刺激產卵的影響。將不同溶劑萃取物滴於 I 形管一端網子之濾紙( 9 cm )上,另一端僅滴溶劑做為對照組,比較二者對產卵刺激之差異。結果顯示,比較 I 形管二端在網子上及圓筒管壁上之平均產卵量,以網子上含有來自密閉壓克力箱內 Solanum viarum 葉片氣味之丙酮或正己烷萃取物,及浸泡於正己烷或二氯甲烷之葉片萃取物等之平均產卵量,較對照組有顯著性差異;然而以乙醚蒸餾出的葉片萃取物則可明顯抑制番茄夜蛾產卵。比較圓筒管壁上之平均產卵量,則顯示只有浸泡於正己烷或二氯甲烷之葉片萃取物較對照組具顯著刺激番茄夜蛾產卵,但以其他萃取方法獲得之葉片萃取物對番茄夜蛾則無明顯刺激產卵作用。 |
英文摘要 | Effects of Solanum viarum leaf extracts on stimulating the oviposition of Helicoverpa armigera (H ü bner) were evaluated in 2-choice I-tubes bioassay (250 cm long x 30 cm in diameter). Different types of solvent-extracts were placed on filter paper (90 mm) and compared their oviposition stimulation against the check with only the respective solvent in each treatment. Oviposition was evaluated by the mean number of eggs laid on both net and cylinder. There were significant difference in the mean number of eggs laid on the net containing the leaf extracts with acetone and hexane airtight acrylic, hexane and methylene chloride dipping. However, the aqueous extract trapped in diethyl ether from the steam distillation appeared to inhibit the oviposition of H. armigera . From the mean number of eggs laid on the cylinder, it showed that only the dipping in hexane and methylene chloride significantly stimulated the oviposition of H. armigera but no significant difference was observed in the extracts from the other methods. |
