Diplomsko delo, Univerza v Mariboru, Fakulteta za naravoslovje in matematiko, Oddelek za biologijo, 2013. IZVLEČEK Gregarine (Protozoa: Apicomplexa: Eugregarinida) so paraziti v prebavilih in telesnih votlinah nevretenčarjev, kot so kolobarniki, plaščarji in členonoţci. Poleti in v jeseni leta 2013 sem pregledala prebavila 30 osebkov iz 11 vrst kobilic (Orthoptera) iz severovzhodne Slovenije. Našla sem sedem vrst gregarin: Leidyana gryllorum (Cuenot, 1897); Gregarina delmasi Tuzet et Rambier, 1953; Gregarina cf. proteocephala Semans, 1939; Gregarina sp. 1; Gregarina sp. 2; Gregarina sp. 3 in Gregarina sp. 4. Od teh je vrsta Gregarina cf. proteocephala Semans, 1939 za Slovenijo prvič zabeleţena. Identitete štirih vrst iz rodu Gregarina nisem mogla ugotoviti. Ključne besede: Eugregarinida, gregarine, paraziti, kobilice, Orthoptera, Slovenija. 1 LAVRENČIČ, Š.: Gregarine (Protozoa: Apicomplexa: Eugregarinida) v prebavilih kobilic (Orthoptera).

Graduation Thesis, University of Maribor, Faculty of Natural Sciences and Mathematics, Department of Biology, 2013. ABSTRACT Gregarines (Protozoa: Apicomplexa: Eugregarinida) are parasites in the digestive tract and body cavities of invertebrates, such as annelid, tunicates and arthropods. In the summer and in the autumn of 2013, I have examined the intestines from 11 species of 30 locust (Orthoptera) from NE Slovenia. I found seven species of gregarines: Leidyana gryllorum (Cuenot, 1897); Gregarina delmasi Tuzet et Rambier, 1953; Gregarina cf. proteocephala Semans, 1939; Gregarina sp. 1; Gregarina sp. 2; Gregarina sp. 3 and Gregarina sp. 4. The species Gregarina cf. Proteocephala Semans, 1939 is the first time recorded in Slovenia. Four species of the genus Gregarina I have not been able to identify. Key words: Eugregarinida, Gregarines, parasites, Orthoptera, grasshoppers, Slovenia. 2 LAVRENČIČ, Š.: Gregarine (Protozoa: Apicomplexa: Eugregarinida) v prebavilih kobilic (Orthoptera).
