Sawflies (Hymenoptera, Symphyta) in the biotopes of Kopački rit

During 2003, entomological investigations were carried out into the sawflies (Hymenoptera, Symphyta) of Kopacki Rit Nature Park, with a grant from the Insect Research topic of the Ministry of Culture, Zagreb, and Project 0122025 financed by the Ministry of Science, Education and Sport under the title Entomofauna of Kopacki Rit of Osijek. At three groups of stations: inundated, forest and open ground (a total of 8 stations) a total of 220 individuals were sampled selectively with a net and with sticky tablets. From this material, 73 species of sawfly were determined. There is a clear differentiation of the inundated area at which the presence of only 15 species was recorded , but with great abundance, 7 species being recorded only in such kind of habitat (they were recorded only in the inundated area). This investigation also demonstrated that the borderline area between forest and meadow was the best habitat for the sawfly. At this kind of station in Tikves, the presence of 35 species was recorded.
