产生蜜露的昆虫和蚂蚁之间的互利关系改变了植物挥发物的排放，但这种变化是否改变了照顾产生蜜露的昆虫的蚂蚁或寄生产生蜜露的昆虫的黄蜂的行为仍然未知。这项研究比较了蚂蚁 Tetramorium bicarinatum 和寄生蜂 Aenasius bambawalei 对感染粉蚧粉虱或感染粉蚧和饲养粉蚧的蚂蚁的棉花植株气味的行为反应。蚂蚁无法区分仅感染粉蚧的植物的挥发物和感染粉蚧和蚂蚁的植物的挥发物。同样，天真的黄蜂也无法区分两种处理方法中的挥发物。相比之下，经验丰富的黄蜂更喜欢来自被粉蚧和蚂蚁侵染的植物的挥发物。挥发性分析表明，当植物被粉蚧和蚂蚁侵染时，与植物未侵染或仅被粉蚧侵染时相比，MeSA 的量增加，烟酸甲酯的量减少。因此，粉蚧和蚂蚁之间的互利共生改变了棉花植物排放的挥发物，从而增加了A. bambawalei（但不是蚂蚁）对植物的吸引力。
Mutualisms between honeydew-producing insects and ants change the emission of volatiles from plants, but whether such changes alter the behaviors of ants that tend honeydew-producing insects or wasps that parasitize honeydew-producing insects remain unknown. This study compared the behavioral responses of the ant Tetramorium bicarinatum and the parasitoid wasp Aenasius bambawalei to odors from cotton plants infested with the mealybug Phenacoccus solenopsis or infested with the mealybug and the ant, which tends the mealybug. The ant could not distinguish between the volatiles from plants infested with the mealybug alone and those from plants infested with the mealybug and the ant. Likewise, naïve wasps failed to distinguish between volatiles from the two treatments. In contrast, experienced wasps preferred volatiles from plants infested with the mealybug and the ant. Volatile analysis showed that the amounts of MeSA were increased and those of methyl nicotinate were decreased when plants were infested by the mealybug and the ant rather than when plants were uninfested or were infested by the mealybug alone. Thus, the mutualism between the mealybug and ant changed the volatiles emitted by cotton plants such that the attraction of A. bambawalei (but not that of the ant) to the plants was increased.
