蚂蚁（Formica japonica）是杂食性蚂蚁，工蚁会捕猎其他昆虫作为食物。在这项研究中，研究了工蚁和蚁后的种间攻击行为。行为实验表明，工蚁的种间攻击性明显高于蚁后。工蚁对蟋蟀表现出掠夺性攻击行为，而蚁后则引发威胁行为，但不会攻击蟋蟀。为了研究调节攻击动机的神经元机制，通过使用高效液相色谱（HPLC）和电化学检测（ECD）测量生物胺来检查大脑中生物胺在诱发攻击行为中的作用。工蜂和蜂王之间的章鱼胺（OA）水平没有显着差异，但蜂王大脑中的N-乙酰章鱼胺（NacOA）水平显着高于工蜂。这项研究表明，大脑中的 OAergic 系统必须参与控制蚂蚁的攻击动机。
The ant, Formica japonica, is polyphagous and workers hunt other insects as foods. In this study, interspecific aggression was examined in the workers and queens. Behavior experiments demonstrated that interspecific aggressiveness was significantly higher in workers than queens. Workers showed predatory aggressive behavior towards crickets, on the other hand, queens elicited threat behavior but they didn't attack crickets. In order to investigate neuronal mechanisms underlying regulation of aggressive motivation, the role of biogenic amine in the brain in evoking aggressive behavior was examined by measuring biogenic amine using high-performance liquid chromatography (HPLC) with electrochemical detection (ECD). No significant difference in the octopamine (OA) level was found between workers and queens, but the level of N-acetyloctopamine (NacOA) in the brain of queens was significantly higher than that of workers. This study suggests that OAergic system in the brain must involve in controlling aggressive motivation in the ants.
