大量的研究表明，带菌者几乎从不随机进食。通常，个体宿主和宿主物种的一个子集比从其丰度预期的更频繁地被喂食，这可以放大病原体传播。然而，媒介与其宿主之间接触模式变化的驱动因素尚未得到很好的理解，即使是在相对充分研究的系统中，如西尼罗河病毒（WNV）。我们比较了西尼罗河病毒七种鸟类宿主物种的栖息高度和栖息聚集大小与公共和非公共栖息地的寻宿主蚊子（尖音库蚊）丰度模式。首先，寄主蚊子的数量随着高度的增加而增加，并且增加了蚊子对栖息在树冠较高的物种的取食偏好。第二，有几百倍的蚊子每只鸟被困在美国知更鸟（Turdus migratorius）公共栖息地相比，非公共栖息地，这可以减少传输和这个关键的放大宿主物种。第三，季节性变化的公共栖息地形成可能部分解释观察到的季节性变化的蚊子喂养模式，包括减少喂养公共栖息知更鸟。这些结果说明了宿主和病媒对栖息地的利用以及宿主的社会聚集是如何影响病媒-宿主相互作用的，并将鸟类的行为生态学与病媒传播疾病向人类的传播联系起来。
Extensive work has shown that vectors almost never feed at random. Often, a subset of individual hosts and host species are fed on much more frequently than expected from their abundance and this can amplify pathogen transmission. However, the drivers of variation in contact patterns between vectors and their hosts are not well understood, even in relatively well-studied systems such as West Nile virus (WNV). We compared roosting height and roost aggregation size of seven avian host species of WNV with patterns of host-seeking mosquito (Culex pipiens) abundance at communal and non-communal roost sites. First, host-seeking mosquito abundance increased with height and paralleled increased mosquito feeding preferences on species roosting higher in the tree canopy. Second, there were several hundred-fold fewer mosquitoes per bird trapped at American robin (Turdus migratorius) communal roosts compared to non-communal roost sites, which could reduce transmission from and to this key amplifying host species. Third, seasonal changes in communal roost formation may partly explain observed seasonal changes in mosquito feeding patterns, including a decrease in feeding on communal roosting robins. These results illustrate how variation in habitat use by hosts and vectors and social aggregation by hosts influence vector-host interactions and link the behavioral ecology of birds and the transmission of vector-borne diseases to humans.
