【摘要】 目的构建黑腹果蝇(Drosophila melanogaster)的梳理行为谱并研究其行为序列。方法使用集中个体取样法和扫描取样法观察记录目标动物的行为,Ethom软件处理数据。结果黑腹果蝇梳理行为共计15种,且具特定的行为序列:前足参与的梳理行为很少与后足参与的梳理行为产生联系,当梳理前翅时,果蝇会趋向于继续梳理前翅或转向梳理身体后部;而当梳理身体后部时,果蝇会趋向于继续梳理身体后部或转向梳理前翅而不会趋向于梳理身体前部。去翅后梳理行为组成及行为序列均未改变。结论果蝇的梳理行为是一种先天定型行为,各梳理行为之间非随机出现,具有特定的时间序列。更多还原

【Abstract】 Objective To develop grooming behavioral ethogram of fruitfly Drosophila melanogaster and to study its behavioral sequence.Methods Grooming behavior of fruitfly was observed by focal sampling and scan sampling,and the data analysis was carried out by software Ethom.Results A total of 15 types of grooming behavior were displayed by fruitfly,with no significant differences between genders.The front legs have significantly more transitions to front legs,and significantly less to wings and rear legs,similarly,the rear legs have significantly high transitions to rear legs and wings,but a significantly reduced transition to front legs.(Conclusion)The grooming behaviors of fruitfly Drosophila melanogaster are sterreotype behaviors with specific behavior sequences.更多还原
