摘要:

测定青杨脊虎天牛雌、雄成虫对13种植物挥发物的电生理和行为反应。结果表明: 丁香酚、2-苯乙醇、糠醛、柠檬烯、月桂烯5种挥发物在最大浓度下(1 mol·L-1)均能引起雌雄成虫强烈的触角电位反应(P<0.01); 行为反应测试表明: 柠檬烯在高于或等于10-3 mol·L-1的浓度时对雌虫均有引诱作用(P<0.01),在1和10-1 mol·L-1浓度下能够引诱雄虫(P<0.01); 丁香酚于10-1和10-1mol·L-1浓度下对雌、雄成虫均有引诱作用(P<0.01); 2-苯乙醇在10-1和10-2mol·L-1浓度下均能引诱雌、雄成虫(P<0.01); 浓度为1和10-1 mol·L-1的糠醛对雌、雄成虫产生驱避作用(P<0.01); 月桂烯只在10-1 mol·L-1浓度下对雌、雄成虫有引诱作用(P<0.01); 其他挥发物对青杨脊虎天牛均无明显定向作用。

Abstract:

The electroantennogram(EAG) and behavioral responses of female and male beetles of Xylotrechus rusticus to 13 plant volatiles were tested. The female and male adults exhibited very strong EAG responses(P<0.01)to 1 mol·L-1 Eugenol,2-Phenylethanol,furfural,limonene and myrcene. Limonene exhibited lure effect to females adult (P<0.01),when the concentration higher than or equal to 10-3 mol·L-1 and exhibited lure effect to males at 1 and 10-1 mol·L-1 (P<0.01) concentrations. Eugenol exhibited lure effect to females and males at 10-1 and 10-2 mol·L-1 (P<0.01); 2-Phenylethanol showed lure effect to females and males at 10-1 and 10-2 mol·L-1 concentrations(P<0.01). Furfural exhibited repellent effect to females and males at 1 and 10-1 mol·L-1 concentration(P<0.01). Myrcene exhibited lure effect to females and males at 10-1 mol·L-1 concentration(P<0.01). Females and males showed no distinct directional behavior to the other volatiles.
