将黑腹果蝇雌雄同体引入含有 2 个野生型同种雄性的交配室中。从这些雄性求偶反应的差异来看，使雄性能够区分同种雄性和雌性并仅向雌性进行持续求爱的唯一重要因素是雌性的组织成分。这暂时用女性特有的性信息素来解释。遗传、胚胎学和解剖学方面的考虑表明，成年黑腹果蝇雌性的信息素产生细胞分散在整个体内，并且是雌性背甲、背甲和胸体皮的一部分。行为观察表明，随着雌雄同体引起的兴奋性刺激强度的增加，它最终会被更持久、更长时间地求爱。初步的命运图谱表明，男性和女性之间的行为差异是由位于前方的器官决定的，并且无论目标器官的组成或物理结构如何，这些器官都可以触发行为反应。
D. melanogaster gynandromorphs were introduced into a mating chamber containing 2 wild-type conspecific males. From the differential courting responses of these males, the only important factor that enabled a male to distinguish between conspecific males and females and to direct persistent courtship only toward females was the tissue composition of females. This is tentatively interpreted in terms of a female-specific sex pheromone. Genetic, embryological and anatomical considerations suggested that the pheromone producing cells of adult D. melanogaster females are dispersed throughout, and are part of the female''s tergites, sternites and thoracic integument. Behavorial observations indicated that as the intensity of the excitatory stimuli invoked by a gynandromorph increased, it ended to be courted more persistently and for longer periods of time. Preliminary fate mapping indicated that behavioral differences between males and females are determined by anteriorly located organ(s) and that these organ(s) can trigger behavioral responses regardless of the composition or physical structure of the target organs.
