结果表明，菜青虫优先选择甘蓝亚种的个体作为寄主。对苦味酸根试验呈强阳性反应的甘蓝属植物。结果表明，烯丙基腈是一种特异的甘蓝型油菜引诱剂。幼虫对食物植物的选择是非选择性的，唯一的选择发生在产卵时。结果表明，在营养体期、开花前失去高苦味酸分的植株是这种差异选择的结果。
It is shown that gravid Pieris brassicae L. preferentially select as hosts, individuals of Brassica oleracea L. subsp. oleracea with a strongly positive reaction to the Guignard picrate test. It is suggested that allyl nitrile is a specific attractant for P. brassicae. The larvae are shown to be non‐selective in their choice of food plant, the only selection taking place at egg‐laying. It is suggested that the loss of high picrate score plants during the vegetative, preflowering stage is due to this differential selection.
