在任何有性繁殖的动物中，人们都期望雄性之间发生侵略性的遭遇，因为它们的适应价值;对资源（食物，领土，配偶，社会地位）的竞争在大多数动物物种的自然选择和性选择中起着关键作用。男性与男性之间的互动，当行为发生时，被贴上侵略的标签，它的表现形式从微妙的手势到直接的身体对抗。此外，攻击行为通常是由一个或多个感官形式的物种特异性信号介导的。
在PNAS中，Versteven等人。（3）继续研究果蝇雄性间的声音信号[例如，Jonsson等（4）]，通过部署经典的损伤以及遗传方法来探测苍蝇的“耳朵”在表达攻击行为中的作用，从而提供神经感觉机制数据。作者（3）表明，听觉能力可以影响实验室比赛场地中的二元男性-男性相遇的行为结果。
D.听觉的听觉基础已经对黑腹果蝇在许多大小尺度上的多个生物组织水平进行了大量研究（5）。听觉听觉器官，被称为约翰斯顿器官（JO），是天线的修改的第二部分。先前的研究表明，JO是由声音引起的振动刺激的，例如附近苍蝇拍打翅膀的气流。雄性果蝇伸出一只翅膀，对着目标果蝇短暂地扇动翅膀，从而产生用于交流的突出的声音信号。这种刻板的手势发生在发送者和接收者非常接近的情况下，在一个或最多两个身体长度内。JO很容易看到，并且非常容易进行实验操作，这使得使用经典技术相对容易地使苍蝇耳聋，这些技术可以防止声学振动将JO设置为运动或简单地消融它（图1...

In any sexually reproducing animals, one expects aggressive encounters to occur between/among males because of their adaptive value; competition over resources (food, territory, mates, social status) plays a critical role in both natural and sexual selection in most species of animals (1, 2). Male–male interaction, when behaviorally enacted, is labeled as aggression, and it varies in expression from subtle gestures to outright physically combative encounters. Moreover, aggressive behavior is usually mediated by species-specific signals in one or more sensory modalities.
In PNAS, Versteven et al. (3) continue the study of intermale acoustic signals in Drosophila melanogaster [e.g., Jonsson et al. (4)], advancing it by providing neurosensory mechanistic data by deploying classic lesion as well as genetic methods to probe the role of the fly’s “ears” in expressing aggressive behavior. The authors (3) show that the ability of hearing can affect the behavioral outcome of dyadic male–male encounters in laboratory contest arenas.
The auditory basis of hearing in D. melanogaster has been subject to numerous studies at multiple levels of biological organization over many size scales (5). The auditory hearing organ, known as Johnston’s organ (JO), is the modified second segment of the antenna. Previous work has shown that the JO is stimulated by sound-induced vibrations, such as airflow from the beating wings of a nearby fly. The salient acoustic signals for communication are produced by the male extending one wing and briefly fluttering it at the target receiver fly. This stereotyped gesture takes place with the sender and receiver at very close proximity, within one or at most two body lengths. The JO is easily visible and very accessible for experimental manipulation, which made deafening the fly relative easy using classic techniques that prevent acoustic vibrations from setting the JO into motion or simply ablating it (figure 1 in …
