【摘要】 运用Mallory染色方法,对拟黑多刺蚁(Polyrhachis vicina)脑部形态结构进行了显微观察.结果表明,拟黑多刺蚁脑由前、中、后脑三部分组成:前脑中具有较大的蕈形体,说明它可能具有比较发达的学习和记忆的能力;中脑中具有较大的嗅觉神经纤维球,表明拟黑多刺蚁具有发育良好的嗅觉系统.和其它膜翅目昆虫相比,拟黑多刺蚁前脑中的视叶较小.因此推测,视叶在其觅食、学习、记忆及其他行为中的作用不及中脑嗅叶.后脑在整个脑部占据的面积很小,它在蚂蚁脑部的作用目前还不清楚.更多还原

【Abstract】 The brain structure of Polyrhachis vicina Roger was observed by Mallory dyeing.The results indicated that the brain structure were composed of anterior,middle and hindbrain.A gigantic mushroom body in anterior showed that the ant has transcendent capability in learning and memory.There is big olfactory nerve fiber globe in middlebrain,which indicated that Polyrhachis Vicina Roger ant has well developed olfactory system.However,the optic globe was samller compared with other hymenoptera in anteriorbrain.So the optic system’s function in looking for food,learning,memory and other behavior is inferior to olfactory globe.The hindbrain is very small,and its function is not clear as yet.更多还原
