In the natural world, interactions between individuals occur in groups: an individual must recognize others, identify social opportunities, and discriminate among these options to engage in an interactive behavior. The presence of the group is known to exert an influence on individual group members, and this influence may feed back through the individual to affect behavior across the group. Such feedback has been observed in Drosophila melanogaster, for example, when mating frequency increases in groups composed of mixed strains compared to homogenous groups (Krupp et al., 2008 and Billeter et al. 2012). A working hypothesis is that social processes-to recognize, identify, discriminate, and engage-are innate. They rely on a combination of genetic inheritance, molecular interactions, and cell circuitry that produce neural and immunological responses. Here, we discuss studies that emphasize social interactions in four categories in Drosophila melanogaster: learning, circadian clocks, aggression, and mating. We also speculate that a systems-level network approach to the study of Drosophila groups will be instrumental in understanding the genetic basis of emergent group-level behavior.
在自然界中，个体之间的相互作用发生在群体中：个体必须识别他人、识别社交机会，并在这些选项中进行区分，以参与互动行为。众所周知，群体的存在会对个体成员产生影响，这种影响可能会通过个体反馈，影响整个群体的行为。例如，在果蝇中就观察到了这种反馈，当由混合品系组成的群体与同质群体相比时，交配频率会增加（Krupp 等人，2008 年和 Billeter 等人，2012 年）。一个工作假设是，识别、识别、区分和参与的社交过程是天生的。它们依赖于遗传遗传、分子相互作用和细胞电路的组合，这些组合产生神经和免疫反应。在这里，我们讨论了强调果蝇中四类社交互动的研究：学习、生物钟、攻击和交配。我们还推测，对果蝇群体进行系统级网络方法的研究将有助于理解新兴群体行为的遗传基础。
