在野外遇到同卵异种时，雄性必须迅速探测、整合和处理最相关的信号，以唤起适当的行为反应。求偶和攻击是自然界中繁殖和生存最重要的社会行为：对于雄性来说，在这两者之间做出正确的选择取决于识别对方性别的能力。在大多数种类的苍蝇中，雄性向雌性求爱，并攻击其他雄性。尽管性别识别涉及许多感觉模式，但由作为信息素的特定分子介导的化学感觉通信在帮助雄性区分求偶目标和攻击目标方面起着关键作用。苍蝇使用的化学感觉信号包括挥发性和非挥发性化合物，由嗅觉和味觉系统检测。最近，已经确定了几个假定的嗅觉和味觉受体，它们在性别识别中起着关键作用，使研究人员能够开始绘制神经元回路，将这种感觉信息传递给大脑中更高的处理中心。在这里，我们描述了雄性黑腹果蝇是如何利用味觉和嗅觉做出正确的行为选择的。
Upon encountering a conspecific in the wild, males have to rapidly detect, integrate and process the most relevant signals to evoke an appropriate behavioral response. Courtship and aggression are the most important social behaviors in nature for procreation and survival: for males, making the right choice between the two depends on the ability to identify the sex of the other individual. In flies as in most species, males court females and attack other males. Although many sensory modalities are involved in sex recognition, chemosensory communication mediated by specific molecules that serve as pheromones plays a key role in helping males distinguish between courtship and aggression targets. The chemosensory signals used by flies include volatile and non-volatile compounds, detected by the olfactory and gustatory systems. Recently, several putative olfactory and gustatory receptors have been identified that play key roles in sex recognition, allowing investigators to begin to map the neuronal circuits that convey this sensory information to higher processing centers in the brain. Here, we describe how Drosophila melanogaster males use taste and smell to make correct behavioral choices.
