昆虫的行为受生理和神经系统的调节。生物胺作为神经系统中的神经递质、神经调节剂和神经激素，在刺激行为中起着重要作用。在蚂蚁中，脑胺水平的变化与各种行为特性有关：繁殖、合作和敌意。攻击性也受到神经系统的控制。一些蚂蚁的社会结构是通过蚁后之间的相互攻击建立起来的。然而，也有一些案例显示了生物胺对蚁后攻击的假定作用。一种群居寄生蚁，建立了功能性的一夫一妻制，多个蚁后之间的对抗相互作用导致了统治等级。在这一次，我们检查了日本皇后头部生物胺水平的变化，与观察到的攻击行为有关。在蜂群中，雌蜂通过撕咬和拉扯身体部位来猛烈攻击对方。然而，在晚期蜂王中从未观察到攻击性行为。在血清素（5-HT）、多巴胺（DA）、八胺（OA）和酪胺（TA）四种生物胺的测量中，脱酸盐中5-HT和DA的水平明显高于丙酸盐。OA和TA水平在两组间无显著性差异。此外，在幼蜂（10-30天）和老蜂（6个月以上）组中也证实了类似的变化。日本猕猴、5-羟色胺和DA对攻击动机具有调节作用，与年龄无关。然而，生物胺的变化可能受到其他行为因素的影响。
Insect behavior is regulated by physiological and neurological systems. Biogenic amines play a role in motivating the behavior as neurotransmitters, neuromodulators, and neurohormones in the nervous systems. In ants, the change of brain amine levels is linked to various behavioral properties: reproduction, cooperation, and hostility. Aggressiveness is also manipulated by the neurological systems. The social structures in some ant species are established by aggressive interactions among queens. However, there are a few cases showing the putative role of biogenic amines for the queen aggression.Vollenhovia nipponicais a social parasite ant, which establishes functional monogyny that antagonistic interactions among multiple queens lead to dominance hierarchy. In this time, we examined changes in the levels of biogenic amines in heads of queens inV. nipponica, associated with the observation of aggressive behavior. In the colonies, dealate queens violently attacked toward each other by biting and pulling on body parts. Whereas, the aggressive behavior was never observed in alate queens. In the measurements in four biogenic amines, serotonin (5-HT), dopamine (DA), octopamine (OA), and tyramine (TA), the levels of 5-HT and DA in dealates were significantly higher than those in alates. The levels of OA and TA were not significantly different between them. Moreover, the similar changes were confirmed in the groups of young (10–30 days old) and old queens (more than 6-month old). InV. nipponicaqueens, 5-HT and DA could regulate motivation of aggression, irrespective of age. However, the changes of biogenic amines are possibly affected by other behavioral factors.
