Georgiev 11 Central Laboratory of General Ecology, Bulgarian Academy of Sciences,2 Gagarin Street, 1113 Sofia, Bulgaria; 2 Thracian University,Faculty of Agriculture, 6000 Stara Zagora, BulgariaBulgaria is a country with diverse landscapes and a species-rich vertebrate fauna,which is a prerequisite for diverse fauna of the helminth parasites. The aim of thepresent study is to summarise data on the species diversity of the cestode faunaof Bulgaria. The species composition of the helminth parasites of vertebrateanimals has been a subject of extensive studies during the last 50 years. For thepurposes of several recent biodiversity projects, we summarised the availablefaunistic data on cestodes in Bulgaria. The known taxonomic diversity of theclass Cestoda in this country includes 9 orders, 26 families, 151 genera and 324species. These are 31 species recorded from freshwater and marine fishes, 6 speciesfrom amphibians and reptiles, 215 species from birds and 84 species frommammals. The largest order Cyclophyllidea, which includes parasites oftetrapods (mostly birds and mammals), is represented by 14 families and 288species: Mesocestoididae - 4, Nematotaeniidae - 1, Anoplocephalidae -19,Catenotaeniidae - 5, Progynotaeniidae - 2, Acoleidae - 2, Amabiliidae - 10,Davaineidae - 19, Dilepididae - 67, Dipylidiidae - 2, Paruterinidae - 17,Metadilepididae - 1, Hymenolepididae - 126 and Taeniidae - 13. The noncyclophyllideanorders are represented by a relatively low number of species:Amphilinidea - 1, Caryophyllidea - 7, Diphyllidea - 1, Trypanorhyncha - 2,Tetraphyllidea - 3, Pseudophyllidea - 12, Proteocephalidea - 6 and Tetrabothriidea- 4. These data characterise our country as one of the most fully studied Europeanterritories from point of view of the number of the species recorded. Having in viewthe number of the species recorded from each host group in Europe, we canestimate that the species composition of cestodes from mammals, amphibiansand reptiles is almost completely revealed (perhaps more than 95% ofexpected species are recorded). This percentage for the cestode parasitesfrom birds and freshwater fishes is about 75%, and for cestodes from marinefishes is less than 50%.19:00-21:30Коктейл. Ресторант “Чергата”Cocktail.
