摘　　要：Previous studies have confirmed that both honeybee and Drosophila are capable of learning and memory. This study aimed to investigate whether the house fly （Aldrichina grahami）, with strong instincts to adapt their living environment, have the learning ability to associate odor stimulus to avoid electric shock in free flying state using a device developed by the authors. The result showed the learning ability ofA. grahami at the electric shock voltages of 5 V, 25 V and 45 V AC. When 60 V was used, the flies were frequently injured. Our results indicate that A. grahami is a good model to study the neural mechanism of learning and memory. The paradigm in this study has some advantages that can be used in future studies of free insects.研究证实:蜜蜂和果蝇具有良好的学习记忆能力。利用自主改良的研究装置对另一种具有强大生存本能的双翅目昆虫——巨尾阿丽蝇(Aldrichina grahami)在自由状态下电击回避学习能力进行研究。结果表明,巨尾阿丽蝇具有良好的学习记忆能力,因为当刺激电压范围为5V到45V时,观察到巨尾阿丽蝇有显著的回避电刺激行为,而当电压达到60V时会受到明显伤害。由此推测,巨尾阿丽蝇适合作为神经系统研究的动物模型。该实验所采用的实验范例较以往有所改进,适合作为自由状态下研究昆虫的工具。
