Dynamics of mosquito (Diptera, Culicidae) species richness in samples of dry-ice baited CDC traps in the urban area of Osijek, Croatia

In this paper the results of ten year investigation of mosquitoes using dry ice baited CDC traps in the city of Osijek, Croatia are presented. In the first year we recorded 16 species. During these ten years the total of 20 species were determined. The single method, dry ice baited CDC traps, makes it possible to determine almost entire fauna in a given area. The estimated fauna is statistically calculated. Five non-parametric estimators were chosen for evaluation: one-factorial Jackknife (jackknife-1) ; two-factorial Jackknife (Jackknife-2) ; one-factorial Chao (Chao-1) ; two-factorial Chao (Chao-2) and Bootstrap. The estimated fauna contains between 22 and 29 species. The methods used turned out to be very good when used over a long period of time, because new species were registered even in years without many mosquitoes.
