Detailed knowledge of the habitat requirements of mosquitoes is essential for the
targeted control of vectors. Our research sought to answer how the circumstances of
fine-scale habitat affect the density of mosquito species playing a pivotal role in
human mosquito harm. During the study, CO2 trap collections were carried out for 15
weeks. Habitat mapping was carried out at a radius of 500, 1000, 1500 and 2000 m scales.
Precipitation and water levels data of rivers were also included. We found that, in
urbanized areas occupied by invasive species, mosquito species composition was strongly
determined by the presence of artificial containers occurring in the narrow (radius
< 500 m) environment. The cover of natural habitat types ideal for mosquito breeding
sites at a greater distance (radius & GE; 2000 m) also play a decisive role in the
organization of mosquito assemblages. In the environment of the inhabited regions
(radius & GE; 2000 m), the large extent of the humid grasslands making a mosaic with
forests is also beneficial for mosquito species feeding on humans. In Central Europe,
in urban areas rich in temporarily water-covered mosquito breeding sites in a narrow
habitat environment (radius < 1500 m), robust mosquito harm can appear within a week
after significant precipitation or river floods during warm summers.
