我们发现，蜜蜂通过执行级联的“气味”事件，其中个别蜜蜂直接通过扇他们的翅膀他们的信息素信号，找到他们的女王。蜜蜂创造了一个动态的时空网络，随着时间的推移招募新的广播蜜蜂，因为信息素传播的距离是个体长度的数量级。我们开发了高通量的机器学习工具来识别气味事件的位置和时间，并证明这些事件整合到一个全球“地图”，导致女王。我们使用这些结果来建立一个基于代理的模型，说明了定向信号放大信息素的优势，从而导致一个有效的搜索和聚合过程。蜜蜂群是集体行为的一个里程碑式的例子。为了形成一个连贯的蜂群，蜜蜂通过追踪蜂王的信息素来定位她。但是，遥远的个体如何利用这些在空间和时间中迅速衰减的化学信号呢？在这里，我们结合联合收割机的行为分析与机器视觉检测的有机体的位置和气味（信息素传播通过翅膀扇）的行为来跟踪蜜蜂的搜索和聚集动态。我们发现，蜜蜂集体创造了一个气味介导的通信网络，通过安排在一个特定的空间分布，其中有一个特征的个人之间的距离和方向信号远离女王。为了更好地理解这样一个流介导的定向通信策略，我们开发了一个基于代理的模型，蜜蜂代理遵守简单的，本地的行为规则存在于流环境中的化学信号扩散和衰减。我们的模型作为一个指南，探索物理参数如何影响集体嗅闻行为，并表明，在嗅闻方向偏差增加导致更有效的聚合过程，避免局部平衡配置的各向同性（无方向和轴对称）通信，如小蜜蜂集群，坚持在整个模拟。我们的研究结果突出了一个扩展的经典stigmergy的例子：而不是在环境中存放静态信息，个别蜜蜂本地的感觉和全球操纵的化学浓度和气流的物理场。
We show that bees locate their queen by performing a cascade of “scenting” events, where individual bees direct their pheromone signals by fanning their wings. The bees create a dynamic spatiotemporal network that recruits new broadcasting bees over time, as the pheromones travel a distance that is orders of magnitude the length of an individual. We develop high-throughput machine learning tools to identify the locations and timings of scenting events, and demonstrate that these events integrate into a global “map” that leads to the queen. We use these results to build an agent-based model that illustrates the advantage of the directional signaling in amplifying the pheromones, thus leading to an effective search and aggregation process. Honeybee swarms are a landmark example of collective behavior. To become a coherent swarm, bees locate their queen by tracking her pheromones. But how can distant individuals exploit these chemical signals, which decay rapidly in space and time? Here, we combine a behavioral assay with the machine vision detection of organism location and scenting (pheromone propagation via wing fanning) behavior to track the search and aggregation dynamics of the honeybee Apis mellifera L. We find that bees collectively create a scenting-mediated communication network by arranging in a specific spatial distribution where there is a characteristic distance between individuals and directional signaling away from the queen. To better understand such a flow-mediated directional communication strategy, we developed an agent-based model where bee agents obeying simple, local behavioral rules exist in a flow environment in which the chemical signals diffuse and decay. Our model serves as a guide to exploring how physical parameters affect the collective scenting behavior and shows that increased directional bias in scenting leads to a more efficient aggregation process that avoids local equilibrium configurations of isotropic (nondirectional and axisymmetric) communication, such as small bee clusters that persist throughout the simulation. Our results highlight an example of extended classical stigmergy: Rather than depositing static information in the environment, individual bees locally sense and globally manipulate the physical fields of chemical concentration and airflow.
