【摘要】 为给植物挥发物引诱剂的开发提供理论依据和基础资料,选取了分月扇舟蛾(Clostera anastomosis)和黑杨为试验对象,利用触角电位技术测试了分月扇舟蛾成虫对11种杨树叶片挥发物及其混配物的触角电位反应。结果表明,雌虫与雄虫触角对杨树挥发物的触角电位(EAG)反应没有显著差异;成虫交配前后触角对杨树挥发物的EAG反应同样没有显著差异。将不同化合物进行混配发现,邻羟基苯甲醛、顺-3-己烯醇和丁(子)香酚相互混配时可增强分月扇舟蛾的触角电位活性。通过测定5种挥发物的5种浓度梯度的触角电位活性,发现成虫对混合物的触角电位反应相对值开始随着化合物浓度的升高而升高,但到达一定浓度后,触角电位反应相对值随着浓度的升高而降低。更多还原

【Abstract】 To provide theoretical basis and information for development of herbivore-induced plant volatiles as attractants,Clostera anastomosis were selected to detect the antennal electrophysiological responses to 11 plant volatiles from poplar leaf revealed by electroantennogram(EAG). The female and male adults gave similar EAG responses to poplar volatiles,and the EAG response of the antennae of adults before and after mating was consistent. The antennal activity of C.anastomosis be enhanced by the mixture of three volatiles,salicylaldehyde,cis-3-hexenol and eugenol. By measurement of the antennl electrophysiological activities of C. anastomosis in response to 5 concentration gradients of 5 volatiles,an increase of relative value of EAG response of adults to the mixtures was found as a function of increase in the concentration of the mixture at the beginning,but decreased after wards.更多还原
