    松梢象对红松萜烯类挥发物的触角电位及行为反应

    Electroantennogram and behavioral responses of Pissodes nitidus to terpene volatiles of Pinus koraiensis

    • 摘要: 本文研究了松梢象对寄主红松挥发物组分S型α--蒎烯、R型α--蒎烯、β--蒎烯、β--月桂烯、罗勒烯、莰烯、3--蒈烯及反--柠檬烯8种挥发物,在0.000 4、0.004、0.04、0.4及0.8 mol/L浓度下的触角电位反应及行为反应。结果表明:这8种挥发物单体在各浓度下均能引起松梢象的触角电位(EAG)反应,且相同挥发物EAG反应值随浓度的增加而增加;松梢象尤其对0.4和0.8 mol/L浓度下的S型α--蒎烯、R型α--蒎烯反应较强。“Y”型嗅觉仪行为测定表明,除β--月桂烯无明显定向作用、反--柠檬烯具有明显的驱避作用外,其他6种挥发物对松梢象均表现出不同程度的诱引作用。反--柠檬烯在0.4和0.8 mol/L下具明显驱避作用,驱避率达62.5%~80%;0.4 mol/L的S型α--蒎烯、R型α--蒎烯和罗勒烯对松梢象诱引作用极显著,诱引率达80%以上。说明以上红松挥发物,尤其是S型α--蒎烯、R型α--蒎烯、罗勒烯及反--柠檬烯对松梢象具有较强的潜在行为调控作用。

       

      Abstract: In this study, we tested the electroantennographic (EAG) and behavioral responses of the weevil (Pissodes nitidus) to eight volatile compositions released from red pine (Pinus koraiensis). The volatiles include (1S)-(-)-α-pinene, (1R)-(+)-α-pinene, (1S)-(-)-β-pinene, camphene, β-myrcene, careen, D-limonene and ocimene in a series of concentrations, i.e., 0.000 4, 0.004, 0.04, 0.4 and 0.8 mol/L. The results show that the weevil had higher EAG responses to all eight volatiles in five concentrations compared with the control (P0.05) and its EAG responses intensified with increased concentrations of volatiles. (1S)-(-)-α-pinene and (1R)-(+)-α-pinene caused the most significant EAG responses with concentrations of 0.4 and 0.8 mol/L. The behavioral responses to the eight volatiles were also examined with a Y-tube olfactometer. The weevils presented significantly repellent behavior to D-limone with concentrations of 0.4 and 0.8 mol/L and the repellent rate was 62.5% to 80%. Except β-myrcene, the weevils were attracted to the other six volatiles and most significantly inclined to 0.4 mol/L of (1S)-(-)-α-pinene, (1R)-(+)-α-pinene and ocimene, with trapping rates of above 80%. These volatiles assayed in this study, especially (1S)-(-)-α-pinene, (1R)-(+)-α-pinene, ocimene and D-limone, may be potentially useful as repellents or attractants for the control and management of P. nitidus.
