2007年，在法国西南海岸的Andernos-les-班斯发现了亚洲大黄蜂Vespa velutina Lepeletier巢穴，这是法国首次报告发现的3年后。在接下来的7年里，尽管地方当局制定了销毁政策，但公社的巢穴数量仍在增加。这些巢穴彼此非常接近，导致城市地区每平方公里超过10个巢穴的高密度。新的信息所选择的栖息地的巢，主要和次要位置之间的差异是显而易见的，主要巢主要占据建筑物和人造结构，而次要巢被发现在树上。使用贝叶斯推理方法，我们拟合一个基本模型的观测数据，这使我们能够估计关键的人口参数。该模型拟合对于预测其他风险区域的绒毛弧菌传播和定殖具有高度信息性，并且表明一旦在区域内建立，局部控制对绒毛弧菌传播的影响有限。
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.
