We use symbolic dynamics to describe Drosophila courtship communication. We posit that behavior should be defined in terms of irreducible periodic orbits of fundamental acts. This leads to a first operational definition of behavior, which allows for a fine grained quantitative analysis of behavior. We obtain evidence that during Drosophila courtship, individual characteristics of the protagonists are exchanged (predominantly from the male to the female) and that males in the presence of fruitless males perform a behavioral switch from male to female behavior.
我们使用符号动力学来描述果蝇求偶交流。我们假定行为应以基本行为的不可约周期轨道来定义。这导致了行为的首个操作性定义，从而能够对行为进行精细的定量分析。我们获得的证据表明，在果蝇求偶过程中，求偶双方的个体特征会发生交换（主要是从雄性到雌性），并且在无果基因（fruitless）突变雄性存在的情况下，雄性会发生从雄性行为到雌性行为的行为转变。
