MaleSpodoptera littoralis stimulated by a mixture ofS. littoralis female sex pheromone with a positional isomer and by the pheromone alone, gave greatly amplified electroantennograms (EAGs) when the antennae were connected in series. The technique is described and examples are given of its use in screening extracts for EAG activity. Dose-response curves obtained with this technique are presented and discussed. Through biological amplification, EAG discrimination between the pheromones was increased.
雄夜蛾受到性信息素混合物（包含滨海夜蛾的一种位置异构体）以及单独的性信息素刺激时，若将触角串联，触角的电生理触角图（EAG）会得到极大增强。本文描述了该技术，并提供了使用该技术筛选具有 EAG 活性提取物的实例。本文还展示和讨论了使用该技术获得的剂量反应曲线。通过生物放大，EAG 对信息素的分辨能力得到增强。
