摘要 為了篩選出對藍(lán)莓上黑腹果蠅雌蠅具有驅(qū)避效果的植物精油單組分化合物，本文采用Y形嗅覺儀，評價10種植物精油單組分化合物對該種雌果蠅的驅(qū)避效果，篩選出驅(qū)避效果最優(yōu)的植物精油單組分化合物后進(jìn)行不同體積的混配，測定其對黑腹果蠅雌蠅的驅(qū)避活性。結(jié)果表明：D-檸檬烯、香茅醛2種植物精油單組分化合物對黑腹果蠅雌蠅的驅(qū)避效果最佳，且在濃度10%～50%范圍內(nèi)，驅(qū)避率與濃度呈正相關(guān);30% D-檸檬烯與30%香茅醛以不同體積比混配后，驅(qū)避效果均優(yōu)于其單劑驅(qū)避效果，其中以5∶5的配比對黑腹果蠅雌蠅驅(qū)避率顯著高于其他配比（P

Abstract To screen monocomponents from plant essential oils （PEOs） as repellents for female adults of Drosophila melanogaster， the repellency of the monocomponents derived from 10 PEOs was evaluated by Y-tube olfactometers test. The best candidates were mixed in different volumes to determine the repellent activities against female adults of D.melanogaster. The results suggested that among the screened PEO-derived monocomponents， dipentene and （±）-citronellal were most effective in deterring female adults of D.melanogaster， and the repellency was positively correlated with the concentrations of these monocomponents in the range between 10% and 50%. Mixtures containing different volumes of 30% dipentene and 30% （±）-citronellal outperformed the single monocomponent as repellents for female adults of D.melanogaster， with the solutions mixed at 5∶5 （V∶V） showing the optimal repellency of up to 79.68% significantly higher than other mixing proportion （P
