Research on parasitic arthropods of the Lake Zarnowieckie environs carried out in 1981-1985. Part II. Mosquitoes (Diptera, Culicidae).

In the years 1981-1985 a total of 19,651 specimens mosquitoes were collected in the area of investigation--Lake Zarnowieckie environs. In that amount 15,072 specimens were identified. There were found 26 species belonging to 4 genera: Anopheles, Aedes, Culex and Culiseta. Some of the species found, such as Aedes cantans, Aedes punctor or Culex pipiens are troublesome pests and particularly aggressive to man, possible vectors of many diseases. In the cowsheds there were found 12 species, the most numerous were the specimens of Anopheles genera (92.1% of the collection). The species captured in the open area by means of the man bait were 17 in number. The highest aggressiveness to man was shown by Ae. punctor, Ae. cinereus, Ae. cantans and Ae. annulipes. In the water bodies among the preimaginal forms caught there identified were 22 species. The majority of them were: Culex pipiens and Aedes punctor. A seasonal activity of the Culicidae preimaginal forms was also observed. The considerable environmental changes caused by the construction of the nuclear power plant, and the work of the pump-storage power plant are, as it seems, the main cause of the changes in the species domination observed in this region. Any finau conclusions, however, can be drawn after the further investigations are completed.
