Diversity, ecology and vector potential of mosquito populations (Diptera: Culicidae) in two differentially structured zoological gardens in Germany
The present work focusses on the mosquito populations of two zoological gardens in Germany with the aim to better understand mosquito biology of native species and to contribute to a greater awareness of mosquito and mosquito-borne disease agent surveillance in zoos. For this purpose, data on species composition, blood meal patterns and mosquito-borne pathogens were analysed. The investigated zoological gardens differed not only in their sizes and animal stocks, but also in their surrounding environments. The 160 ha Tierpark Berlin is located in a densely populated urban area, while the 15 ha Zoological Garden Eberswalde is surrounded by forest. To gain an overview about the mosquito fauna of both zoos, adult specimens were caught by aspirating and EVS-trapping during the 2016 season. In addition, larval stages were collected from their breeding sites located in the zoo areas. In total, 2,257 mosquitoes were sampled, belonging to 20 taxa. Seasonal differences between the zoos were documented, both in terms of species composition and the relative abundance of mosquito species collected. As the studied zoos were located in the same climatic region and both locations provided similar breeding sites, differences in species composition were attributed to the entry of mosquitoes from surrounding landscapes. Influencing factors could have been the different sizes of the zoos and variations in the potential host animal populations. According to the vector potential of most frequently ...
