摘　　要：The cholinergic system plays an important role in the central nervous system of insects and is closely related to the complex behavior of insects. The immunohistochemical technique was performed to detect the expression of like-muscarinic acetylcholine receptor M2 in the brain of three castes of Polyrhachis vicina. A positive expression of like-muscarinic acetylcholine receptor M2 was observed in the mushroom body, central body and antennal lobes of the ant brain; but there is great diversity in their location and intensity among worker, queen and male ants. It is speculated that like-muscafinic acetylcholine receptor M2 plays a critical role in the central nervous system, in terms of projecting visual information and olfactory information into the protocerebrum and integrating many inputs.昆虫脑内胆碱能系统在中枢神经系统中起着重要作用,其与昆虫的复杂行为密切相关。本文选取有复杂行为的膜翅目社会性昆虫拟黑多刺蚁为研究材料,用免疫组织化学方法,对毒蕈碱Ⅱ型乙酰胆碱受体类似物在拟黑多刺蚁工蚁、雌蚁和雄蚁脑中进行定位检测。结果表明,毒蕈碱Ⅱ型乙酰胆碱受体类似物在拟黑多刺蚁前脑蕈形体、中央体和中脑嗅叶中普遍存在,但不同品级表达区域和强弱存在差异。这意味着毒蕈碱Ⅱ型乙酰胆碱受体类似物在拟黑多刺蚁视觉信息、嗅觉信息的整合输出中起着重要作用。
