Deforestation precipitates spillover of enzootic, vector‐borne viruses into humans, but specific mechanisms for this effect have rarely been investigated. Expansion of oil palm cultivation is a major driver of deforestation. Here, we demonstrate that mosquito abundance decreased over ten stepwise distances from interior forest into conterminous palm plantations in Borneo. Diversity in interior plantation narrowed to one species, Aedes albopictus, a potential bridge vector for spillover of multiple viruses. A. albopictus was equally abundant across all distances in forests, forest‐plantation edge, and plantations, while A. niveus, a known vector of sylvatic dengue virus, was found only in forests. A. albopictus collections were significantly female‐biased in plantation but not in edge or forest. Our data reveal that the likelihood of encountering any mosquito is greater in interior forest and edge than plantation, while the likelihood of encountering A. albopictus is equivalent across the gradient sampled from interior plantation to interior forest.

婆罗洲从油棕种植园到相连森林的梯度上蚊子多样性和数量的变化

森林砍伐会导致地方性病媒传播病毒外溢到人类身上，但很少有人研究这种影响的具体机制。油棕种植的扩大是森林砍伐的主要驱动力。在这里，我们证明蚊子的丰度在从内部森林到婆罗洲连续棕榈种植园的十个阶梯距离内减少。内部种植园的多样性缩小到一个物种，白纹伊蚊，一种潜在的多种病毒外溢的桥梁载体。一个。albopictus在森林、人工林边缘和人工林的所有距离上都同样丰富，而A . niveus是一种已知的森林登革热病毒载体，仅在森林中发现。一个。albopictus采集在人工林中明显偏向于女性，但在边缘或森林中则没有。我们的数据显示，在内部森林和边缘遇到任何蚊子的可能性比种植园更大，而遇到A . albopictus在从内部种植园到内部森林采样的梯度上是等效的。
