Pheromones mediating social behavior are critical components in the cohesion and function of the colony and are instrumental in the evolution of eusocial insect species. However, different aspects of colony function, such as reproductive division of labor and colony maintenance (e.g. foraging, brood care, and defense), pose different challenges for the optimal function of pheromones. While reproductive communication is shaped by forces of conflict and competition, colony maintenance calls for enhanced cooperation and self-organization. Mechanisms that ensure efficacy, adaptivity and evolutionary stability of signals such as structure-to-function suitability, honesty and context are important to all chemical signals but vary to different degrees between pheromones regulating reproductive division of labor and colony maintenance. In this review, we will discuss these differences along with the mechanisms that have evolved to ensure pheromone adaptivity in reproductive and non-reproductive context.
介导社会行为的信息素是群体凝聚和功能的关键组成部分，对社会性昆虫物种的进化起着重要作用。然而，群体功能的不同方面，如生殖分工和群体维持（例如觅食、育雏护理和防御），对信息素的最佳功能提出了不同的挑战。虽然生殖通讯受到冲突和竞争的影响，但群体维持需要增强合作和自我组织。确保信号（如结构-功能适宜性、诚实性和上下文）的有效性、适应性和进化稳定性的机制对于所有化学信号都很重要，但在调节生殖分工和群体维持的信息素之间存在不同程度的差异。在这篇综述中，我们将讨论这些差异以及为确保生殖和非生殖环境中信息素适应性而进化的机制。
