Asian hornet, Vespa velutina Lepeletier nests were discovered in 2007 in Andernos-les-Bains on the south-west coast of France, 3 years after the first reported sightings in France. The number of nests increased in the commune over the following 7 years, despite local authorities enacting a destruction policy. The nests existed in close proximity to one another leading to a high density of over 10 nests per square kilometre in urban areas. New information on the chosen habitat for nests is presented, and the differences between primary and secondary locations are evident, with primary nests mostly occupying buildings and man-made structures, while secondary nests were found on trees. Using Bayesian inference methods, we fit a basic model to the observational data, which allows us to estimate key demographic parameters. This model fit is highly informative for predicting V. velutina spread and colonisation of other at-risk regions, and suggests that local control has a limited impact on the spread of V. velutina once established within a region.

亚洲大黄蜂的入侵动态，Vespa velutina（膜翅目：Vespidae）：法国西南部公社的案例研究

亚洲大黄蜂 Vespa velutina Lepeletier 的巢穴于 2007 年在法国西南海岸的 Andernos-les-Bains 被发现，距法国首次报道目击事件发生 3 年之后。尽管地方当局颁布了销毁政策，但在接下来的 7 年里，公社的巢穴数量有所增加。这些巢穴彼此靠近，导致城市地区每平方公里超过 10 个巢穴的高密度。提供了有关巢穴栖息地选择的新信息，主要和次要位置之间的差异很明显，主要巢穴主要占据建筑物和人造结构，而次要巢穴则在树上发现。使用贝叶斯推理方法，我们为观测数据拟合了一个基本模型，这使我们能够估计关键的人口统计参数。
