Collective movement behaviours range from temporary aggregations to coordinated mass migrations with synchronous movement. Models show how complex collective patterns can arise from simple rules regulating local interactions between individuals. However, it is not always clear how these rules are implemented by real insects: even simple abstract rules contain non-trivial assumptions about the perceptual abilities of individuals. Here we review the underlying mechanisms of simple forms of aggregation and collective movement focussing on locusts using them as an example of system in which analyses of the underlying molecular and neural mechanisms have become feasible. These and similar studies promise to reveal the physiological rules governing these behaviours.
集体运动行为的范围从暂时的聚集到协调的大规模迁徙，具有同步运动。模型表明，复杂的集体模式如何可以从简单的规则中产生，这些规则调节个体之间的局部相互作用。然而，这些规则是如何被真正的昆虫实现的并不总是清楚的：即使是简单的抽象规则也包含了关于个体感知能力的非平凡假设。在这里，我们回顾了简单形式的聚集和集体运动的潜在机制，以蝗虫为例，分析了潜在的分子和神经机制，这些研究变得可行。这些和类似的研究有望揭示控制这些行为的生理规则。
