Sažetak
In Eastern Croatia, in the vicinity of the city of Osijek there is a large flooded area known as Kopački rit, which, due to its micro-relief and the water regime in the habitats, offers ideal conditions for the development of huge mosquito populations. As the distance between the city area and the flooded region is 1000 meters only, mosquitoes can migrate to the city area very fast and pose great problems. During a two-yera research we monitored the activity and abundance of female mosquitoes in both areas, using the UV light at night. We used a CDC trap with the UV light as attractant to trap mosquitoes. The research was conducted from May to September 2002. and 2003. twice a month. The water levels of the Danube and Drava rivers in 2002. exceeded critical points three times.The year 2003 was extremely dry and no increase of the water level was recorded. Having compared the two years, we found a great difference in temperature and water level values, resulting in a considerable change of the number of trapped individuals and species. The smallest number of individuals werw trapped in the city during the dry spell, and the largest in kopački rit during the flooding of the entire area. The abundance of mosquitoes in thecity was three times less than that of the flooded area, and the number of species was cut down in half. The relationship between the number of mosquitoes and the number of species for a given area was more or less identical for both years. The UV light as attractant trapped 18 species. The species Ae. vexans attracted by the UV light dominant in 2002, followed by An. Maculipennis. During 2003, the most dominant species in both areas was An. maculipennis, with a much reduced abundance of ae. vexans. Using this method we trapped the total of 18 mosquito species: An. claviger, An. maculipennis, An. hyrcanus, U. unguiculata, Culiseta longiareolata, Culiseta annulata, Cq, richiardii, Oc. caspius, Oc. cantans, Oc. excrucians, Oc. sticticus, Oc. cataphylla, Oc. geniculatus, Ae. vexans, Ae. cinereus, Cx. pipiens, Cx. modestus, Cx. territans.
