Abstract :

The family Megachilidae with more than 4000 wordwide described species is the thirth family of polliniting bees. In this research, in order to investigating the species diversity of Megachilidae, SDR software was used in different regions. The number of species in three counties Yazd, Mehriz and Taft, abundance percentage of each species than total species that collected is determined. The indices of  abundance, diversity, evenness, richness species and also habitat similarity index for 48 species that collected in the three counties was calculated during 2012 and 2013. Megachile rubripes with relative abundance 48% in Yazd county in 2012, Anthidium florentinumwith relative abundance 22.5% in 2013, Megachile pilicrus with relative abundance 26.3% in Mehriz county in 2012, A. florentinum with abundance 19.3% in 2013, Lithurgus chrysurus with relative abundance 23.8%% in Taft county in 2012, Osmia  caerulescens  with relative abundance 29% in 2013 have the most abundance between species. According to alfa species diversity indices, determined that Mehriz and Taft counties have hiegher species diversity in 2013. According to satatistic comparation of evenness indices of species of Yazd, Mehriz counties and also Taft county has similarity evenness in 2012, 2013, but species abundance evenness was more in Mehriz and Taft counties than Yazd county. Species evenness was similar in Mehriz and Taft counties in 2012, 2013. Rarefaction method showed that Taft county has hiegher richness species in 2012. β diversity index showed that Mehriz and Taft counties have the most similarity in 2012, 2013.
