Abstract

Drosophila flies were collected in and around Raipur district (21015 N 81037 E) during different seasons of 2014 to 2015. A total of 3462 individual flies comprising of 8 different species of three subgenus namely, Sophophora, Scaptodrosophla (D. Fauna) and Anaprionus(Z-Indiana)were collected by net weeping method. Subgenus Sophophorawas predominant with six species and Subgenus Dorsilopha or Anaprionusand Scaptodrospilawas least represented species. The diversity of Drosophila community was assessed by using Simpson, Berger-Parker, Evenness and Shannon-Wiener indices. Simpson index was low at 0.1993 in Pamgarh which indicates high diversity. Cluster analysis method was used to analyse the species occurrence. Statistical analysis revealed a uniform distribution pattern of drosophila species in Raipur region.
