Despite numerous studies that showed negative effects of landscape anthropisation on species abundance and diversity, the relative effects of urbanisation, deforestation, and agricultural development as well as the spatial extent at which they act are much less studied. This is particularly the case for mosquitoes, which are the most important arthropods affecting human health.
We determined the scale of effect of these three landscape anthropisation components on mosquito abundance and diversity. We then assessed which landscape variables had the most effect as well as their independent positive or negative effects.
We used mosquito data collected by Schaffner and Mathis (2013) in 16 sampling sites in Switzerland. We measured forest, urban and agricultural amounts in 485 concentric landscapes (from 150 to 5000 m radius) around each sampling site. We then identified the spatial extent at which each landscape metric best predicted abundance and diversity of mosquito species and compared the effect size of each landscape component on each response variable.
In Switzerland, urbanisation and deforestation have a greater influence on mosquito diversity than agricultural development, and do not act at the same scale. Conversely, the scale of effect on mosquito abundance is relatively similar across the different landscape anthropisation components or across mosquito species, except for . However, the effect size of each landscape component varies according to mosquito species.
The scale of management must be selected according to the conservation concern. In addition, a multi-scale approach is recommended for effective mosquito community management.

尽管众多研究表明景观人为化对物种丰度和多样性有负面影响，但城市化、森林砍伐和农业发展的相对影响以及它们作用的空间范围却鲜少被研究。对于蚊子这种影响人类健康的最重要节肢动物而言，情况尤其如此。
我们确定了这三种景观人为化因素对蚊子丰度和多样性的影响规模。然后评估了哪些景观变量影响最大以及它们各自的独立正向或负向影响。
我们使用了沙夫纳和马西斯（2013年）在瑞士16个采样点收集的蚊子数据。我们测量了每个采样点周围485个同心景观（半径从150米到5000米）中的森林、城市和农业用地面积。然后我们确定了每个景观指标能最佳预测蚊子物种丰度和多样性的空间范围，并比较了每个景观因素对每个响应变量的效应大小。
在瑞士，城市化和森林砍伐对蚊子多样性的影响比农业发展更大，且作用规模不同。相反，除了……之外，不同景观人为化因素或不同蚊子物种对蚊子丰度的影响规模相对相似。然而，每个景观因素的效应大小因蚊子物种而异。
必须根据保护需求选择管理规模。此外，建议采用多尺度方法进行有效的蚊子群落管理。
