Setting up a survey may be very complex, especially when no previous data are available on the population of interest. Survey results must be non debatable (i.e. whose results are not open to question and cannot be interpreted in different ways) and precise enough to allow to answer the initial research question. A probabilistic sampling design with sufficient samples for acceptable precision and robust conclusions is then a legitimate sampling strategy. This study objective is to set up an efficient survey of Aedes albopictus on a newly colonized French city where no data are available yet. Following a method we previously published, we use a virtual ecology approach to select the most cost-efficient sampling design with appropriate sample size. This implies modelling an Aedes albopictus population based on another actual population data and testing sampling strategies on this virtual population. This allows us recommending a sampling procedure on this city to achieve precise estimates of tiger mosquitoes probability of presence.

进行调查可能非常复杂，尤其是在没有有关感兴趣人群的先前数据可用时。调查结果必须是无争议的（即其结果不容置疑，并且不能以不同的方式解释），并且必须足够精确，以能够回答最初的研究问题。具有足够的样本数以获得可接受的精度和可靠结论的概率抽样设计便是一种合法的抽样策略。这项研究的目的是在尚无数据的新殖民法国城市建立白纹伊蚊的有效调查。按照我们先前发布的方法，我们使用虚拟生态学方法来选择具有适当样本量的最具成本效益的抽样设计。这意味着对白纹伊蚊进行建模基于另一个实际人口数据并对该虚拟人口测试抽样策略的人口。这使我们可以建议对该城市进行抽样，以准确估计老虎蚊子的存在概率。
