在密歇根州四斑按蚊的沼泽栖息地，对水的表面微层进行取样，发现与地下水样品相比，它富含细菌。表层微层和次表层微层的细菌总数分别为18.8 × 106/ml和65.4 × 106/ml（平均值为35.9 × 106/ml;n= 13），次表层微层和次表层微层的细菌总数分别为3.8 × 106/ml和14.3 × 106/ml（平均值为7.8 × 106/ml;n= 13）。具体而言，表面微层具有较高浓度的三种形态类型的细菌（球菌，杆，杆附着在碎屑颗粒）。鉴于细菌是蚊幼虫的重要食物，我们认为，界面摄食行为的An。quadramaculatuslarvae使它们能够利用表面微层，一个食物丰富的区域。
Sampling of the surface microlayer of water in a marsh habitat ofAnopheles quadrimaculatusSay in Michigan revealed it to be enriched with bacteria compared with subsurface water samples. Concentrations of total numbers of bacteria ranged from 18.8 × 106/ml to 65.4 × 106/ml (mean, 35.9 × 106/ml;n= 13) in surface microlayer samples, and from 3.8 × 106/ml to 14.3 × 106/ml (mean, 7.8 × 106/ml;n= 13) in subsurface samples. Specifically, the surface microlayer had higher concentrations of three morphotypes of bacteria (cocci, rods, and rods attached to detritus particles). Given that bacteria are an important food of mosquito larvae, we suggest that the interfacial feeding behavior ofAn. quadrimaculatuslarvae allows them to exploit the surface microlayer, a food-rich zone.
