Electroantennograms (EAGs) were recorded from male and female cabbage seed weevils (Ceutorhynchus assimilis Payk.) in response to volatiles isolated and identified from the odor of oilseed rape (Brassica napus ssp.oleifera DC. cv. Ariana). Relatively large EAGs were obtained on stimulation with volatiles produced by the oilseed rape crop at the time when seed weevils were actively searching for host plants. Artificial rape odor without certain key volatile compounds was in most cases significantly less stimulatory than odor containing these volatiles. There were significant differences in the EAG response of the sexes ofC. assimilis to the green leaf volatiles of oilseed rape and several terpenes present in rape flower odor. The importance of the qualitative and quantitative composition of host-plant odor in host location byC. assimilis is discussed.
电生理触角反应（EAGs）记录了雄性和雌性甘蓝籽象鼻虫（Ceutorhynchus assimilis Payk.）对从油菜（Brassica napus ssp.oleifera DC. cv. Ariana）气味中分离和鉴定出的挥发物的反应。在油菜作物产生的挥发物刺激下，雄性和雌性甘蓝籽象鼻虫在积极寻找寄主植物时，会产生相对较大的 EAGs。没有某些关键挥发性化合物的人工油菜气味在大多数情况下的刺激性明显低于含有这些挥发性化合物的气味。油菜绿叶挥发物和几种存在于油菜花香中的萜烯对 C. assimilis 雌雄两性的 EAG 反应有显著差异。讨论了寄主植物气味的定性和定量组成在 C. assimilis 寄主定位中的重要性。
