We describe a low-cost system for monitoring the behavioral activity of the fruit fly, Drosophila melanogaster. The system is readily adaptable to one or more cameras for simultaneous recordings of behavior from different angles and can be used for monitoring multiple individuals in a population at the same time. Signal processing allows discriminating between active and inactive periods during locomotion or flying, and quantification of subtler movements related to changes in position of the wings or legs. The recordings can be taken continuously over long periods of time and can thus provide information about the dynamics of a population. The system was used to monitor responses to caffeine, changes in temperature and g-force, and activity in a variable size population.
我们描述了一个低成本的系统，用于监测果蝇的行为活动。该系统可以轻松适应一个或多个摄像头，以便从不同角度同时记录行为，并且可以同时监测群体中的多个个体。信号处理可以区分运动或飞行期间的活动和不活动期，并量化与翅膀或腿部位置变化相关的更微妙的运动。记录可以长时间连续进行，因此可以提供有关群体动态的信息。该系统用于监测对咖啡因、温度和 g 力变化的反应，以及在可变大小的群体中的活动。
