BLOOD MEAL TAKING OF SOME HORSE FLIES SPECIES (DIPTERA, TABANIDAE) ON HORSES (EQUUS CABALLUS)

Istraživanje mjesta uzimanja krvnih obroka obada na konjima, obavljeno je tijekom 1993. godine na pašnjaku u Petrijevcima CR 05. Lovnom mrežicom na konjima uhvaćeno je 2010 jedinki. Sve uhvaćene jedinke su ženke. U sakupljenom uzorku utvrđeno je 26 vrsta obada od kojih su Haematopota bigoti i Hybomitra ucrainica nove u fauni Hrvatske. Obadi su svrstani u potporodice Chrysopsinae i Tabaninae, te rodove Chrysops, Arylotus, Hybomitra, Tabanus, Heptatoma i Haematopota. Dokazano je X² (Hi - kvadrat) testom da vrste Haematopota subcylindrica, Haematoppota pluvialis, Chrysops parallelogrammus, Hybomitra ciureai, Tabanus bromius i Tabanus autumnalis signifikantno razlikuju pojedine dijelove tijela konja pri uzimanju krvnih obroka, jer se na taj način smanjuje kompeticija među vrstama.The research of the horse flies blood meal taking location, the pasture in the village Petrijevci CR 05, took place in 1993. With the help of the net there were collected 2010 specimens, all of which were female. In the collected sample we established 26 species two of which Haematopota bigoti and Hybomitra ucrainica were new for Croatia. Horse flies to belong subfamily Chrysopsinae and Tabanidae, and genera Chrysops, Atylotus, Hybomitra, Tabanus, Heptatoma and Haematopota. X² test demonstrated that species Haematopota subcylindrica, Hameatopota pluvialis, Chrysops parallelogrammus, Hybomitra ciureai, Tabanus bromius and Tabanus autumnalis significantly distinguish between certain parts of the horse while taking their blood meal. In that way is diminished the competitive relationship between some species
