Central to the problem of biological invasions, human activities introduce species beyond their native ranges and participate in their subsequent spread. Understanding human-mediated dispersal is therefore crucial for both predicting and preventing invasions. Here, we show that decomposing human-mediated dispersal into three temporal phases: departure, transport and arrival, allows to understand how the characteristics of human activities and the biological traits of species influence each phase of the dispersal process, and ultimately govern invasion pathways in insects. Integrating these precise mechanisms into future invasion models should increase their realism and generalization for any potential insect invader. Moreover, understanding these mechanisms can provide insight into why some invasive insects are more widely distributed than others, and to estimate risks posed by species that have not yet been introduced.
生物入侵问题的核心在于，人类活动将物种引入其原生范围之外，并参与了它们随后的传播。因此，了解人为介导的扩散对于预测和防止入侵至关重要。在这里，我们表明，将人为介导的扩散分解为三个时间阶段：出发、运输和到达，可以帮助我们理解人类活动的特征和物种的生物学特征如何影响扩散过程的各个阶段，并最终控制昆虫的入侵途径。将这些精确的机制纳入未来的入侵模型中，应该会提高它们对任何潜在入侵昆虫的现实性和通用性。此外，了解这些机制可以深入了解为什么一些入侵性昆虫的分布范围比其他昆虫更广，并估计尚未引入的物种所带来的风险。
