Diversity of dung beetles was studied from 3 different forest sites from Sirinthorn Dam area in Unbonrachathanee province. A total of forty five pig dung baited traps (fifteen traps/site) were used to trap dung beetles from the three studied sites per time. Data were collected five times between January – September 2011. A total of 8,763 dung beetle individuals was found. Among those 7,130 was diurnal beetle and 1,633 was nocturnal beetle. A total of 68 species from 7 genera as Aphodius, Caccobius, Catharsius, Copris, Paragymnopleurus, Synapsis and Onthophagus. The genus Onthophagus was the most abundant with 56 species. The Shannon-Wiener diversity index (H’) of diurnal and nocturnal dung beetle was highest at the first forest site of savanna mixed sparse forest. Dung beetles were the most abundant in individuals and number species in early rainy season (July) and was higher than in the dry season (January and March). The dung beetles diversity and diversity index can use as an indicator for forestry management.
