scarab beetle (coleoptera: scarabaeidae) fauna in ardabil province, north west iran

background: dung beetles of coleoptera associated to undisturbed cattle droppings in pastures present great diver sity and abundance. dung beetles also play an important role for transmission of some helminthes to human and cat tle. this study was made to survey the biodiversity and abundance of these beetles in ardebil province, western iran. methods: according to the field study all beetles attracted to fresh cow dung in five areas of ardebil province in cluding namin, ardabil, meshkinshahr, neer and sarein were collected and identified. they were collected during summer 2007 from june to september, with general peaks appearing to be correlated with temperature mainly at 11 a.m to 15 p.m. the samples were identified using appropriate systematic key. results: a total of 231 specimens belonging to 9 beetle genera and at least 15 species were identified as euoniticel lus fulvus, sisyphus schaffaer, euonthophagus taurus, copris lunaris, chironitis pamphilus, gymnopleurus coriarus, euonthophagus amyntas, caccobius schreberi, onthophagus speculifer, onthophagus furcatus, aphodius, lugens, apho dius fimetarius, a. scrutator, geotrupes spiniger and g. stercorarius the most abundant and diverse subfamilies were coprinae, geotrupinae, and aphodiinae. conclusion: we found 15 species of dung beetles occurred in the region. the prevalence of each species is varied depending on location. some of them play an important role for helminths transmission of veterinary and public health importance. the finding will provide a clue for pasture management as well as public health monitoring and surveillance of the disease transmitted by dung beetles.
