据报道，蚕豆植物蚕豆(Vicia faba, cv。被豌豆蚜虫（Acyrthosiphon pisum）侵染的“萨顿”（the Sutton）吸引了一种专门的寄生性蚜虫（Aphidius ervi），这些蚜虫是从英国、意大利和保加利亚的种群中收集的，这些种群以前对被寄主侵染的植物挥发物没有任何经验。在日本北海道采集的蚜虫也被寄主侵染的蚕豆植物的挥发物所吸引。当黄蜂被允许在受感染的植物上出现时，在y管嗅觉仪中，“Nintoku Issun”的气味比来自完整植物的气味更受欢迎，但在干净的培养皿中出现的黄蜂在两种气味来源之间没有明显的选择。当人工暴露于受侵染植物挥发物时，黄蜂对受侵染植物挥发物的偏好明显高于完整植物的挥发物。在进一步的风洞研究中，当黄蜂暴露在受感染的植物挥发物中时，更多的黄蜂降落在受感染的植物上，而不是完整的植物上。然而，幼稚的黄蜂对受感染的植物没有表现出更高的着陆反应。这些数据表明，北海道品系的ervi在寻找寄主行为中对受侵染植物挥发物的反应需要学习。
It has been reported that volatiles from broad bean plants, Vicia faba (cv. ‘the Sutton’) infested by the pea aphid, Acyrthosiphon pisum, attract a specialist parasitoid Aphidius ervi, collected from populations in England, Italy and Bulgaria, which had no previous experience of the host-infested plant volatiles. Aphidius ervi collected in Hokkaido, Japan were also attracted to volatiles from host-infested broad bean plants (cv. ‘Nintoku Issun’) in preference to those from intact plants in a Y-tube olfactometer when the wasps were allowed to emerge on the infested plants, but wasps that had emerged in a clean Petri dish showed no significant choice between the two odor sources. When artificially exposed to the infested plant volatiles during emergence from the mummy, the wasps showed a significant preference for infested plant volatiles over those from intact plants. In further studies in a wind tunnel, significantly more wasps landed on infested plants than on intact plants when wasps were exposed to infested plant volatiles. Naive wasps, however, did not show a higher landing response to infested plants. These data suggest that learning is required by A. ervi of the Hokkaido strain for their response to infested plant volatiles in their host searching behavior.
