简介：社会昆虫展览建筑群学习和记忆机制当时foraging。Vespulagermanica(Fab)(Hymenoptera：Vespidae)是一只侵略社会黄蜂经常undepleted食物来源上的牧草，做在资源和巢之间的几架班机。以前的研究证明了在这重定位的行为期间，黄蜂学会把食物与某个地点联系，并且能记起这个协会1h以后。在这个工作，我们评估了这黄蜂种是否能够在24h以后检索一个确定的协会。为这个目的，我们训练了自由飞的个人从位于一个试验性的数组的一个试验性的盘子(feeder)收集proteinaceous食物。150个个人的一个总数被给予2，4，或8访问。在训练阶段以后，数组以后，但是这次再被搬迁并且设置24h第二个引诱盘子被放对第一相反。在24h以后，我们记录了回到了从以前有学问的喂车站或nonlearned车站收集了食物的试验性的区域和那些的黄蜂的率。在严峻的阶段期间，而归还黄蜂的率与4或8训练了，我们观察到黄蜂的低率与2训练了收集还给试验性的区域(22%)的收集访问更高(51%和41%，分别地)。而且，与8喂的访问训练的黄蜂比从nonlearned那只做了的那些以更高的率从以前有学问的喂车站收集了食物。相反，黄蜂训练了2或4次以类似的率选择了两个喂的车站。因此，显著地，更多的黄蜂在8架重复foraging班机以后然而并非在仅仅2或4访问以后回到了以前有学问的喂车站。这是在V表明长期的空间记忆的存在的第一份报告。germanica黄蜂。
