Abstract

The monitoring of mosquito population for the eventual purpose of better mosquito control happened in Osijek from 1995-2004. The primary method research-monitoring of mosquitoes used was dry ice baited CDC-traps for a period of 10 years. This provided significant information on mosquito species, their dynamics and seasonal activity. A total of 207,136 mosquito specimens was collected. Among this number 20 species were identified, however, 7 species made up 99% of the total. From these 7, three ecological groups based on breeding sites were determined: flood water mosquitoes, container breeding mosquitoes, and permanent and semi-permanent water breeding mosquitoes. The seasonal dynamics of these three groups are shown in this paper. The average dynamics of all mosquito species was reflected in three peaks: at the end of May, in the middle of July (the biggest one) and in the middle of September. The eudominant species was Aedes vexans which comprised 76% of the total mosquito fauna in the investigated area The flood water species highly correlated with the average dynamics of all the species in the area of Osijek as well as with the average water level of the Danube River.
