15对D.分析了雄性和雌性黑腹果蝇求偶行为的时间平稳性、行为多样性、行为相关性、序列特性和信息传递。在求偶的前半期至后半期，雄蛾的定向回跳行为和雌蛾的理毛和站立行为的持续时间发生了变化。男性多样性大于女性多样性;两者都随时间而稳定。相关性分析未能挑出任何特定的男性或女性的行为是有影响力的控制求爱时间。男性行为序列形成了几个多行为循环，女性行为只包括几个终端2元组的过渡。对男性/女性联合转移矩阵进行的传播分析显示，男性向女性的传播率（12%）高于女性向男性的传播率（7%）。这种多变量分析的果蝇求偶行为的神经生物学和进化方面的调查提出了潜在的应用。
Courtship records of 15 pairs of D. melanogaster were analyzed for temporal stationarity of courtship behaviors, behavioral diversity, behavioral intercorrelations, sequential properties and information transmission for both sexes. Durations of 1 male behavior, orient-back and 2 female behaviors, preen and stand still, were changed from the 1st to the 2nd half of courtship. Male diversity was greater than female diversity; both were stationary over time. Correlation analyses failed to single out any particular male or female behaviors as being influential in controlling courtship duration. Male behavior sequences formed several multibehavior loops; female behavior consisted of only a few terminal 2-tuple transitions. Transmission analysis carried out on the joint male/female transition matrix showed a higher transmission rate from males to females (12%) than from females to males (7%). Potential applications of this multivariate analysis to investigations of neurobiological and evolutionary aspects of Drosophila courtship behavior are proposed.
