Abundance and Diversity of Drosophila fruit flies in Nepalese Condition

Abstract

Systematics of Drosophila have not been investigated properly in Nepal. Therefore, the collection of different Drosophila fruit flys species was carried out to record and understand their characteristics during July-October 2023 from various parts of Nepal (high Himalayas to plain condition). The collection was conducted by applying bottle traps and net sweeps. Different species of Drosophila fruit flies were collected and analyzed in the laboratory of Entomology Department of Agriculture and Forestry University, Chitwan, Nepal. More than 10 species of Drosophila were studied in detail and known for their characteristics. Most of the Drosophila species were recognized and recorded at higher altitudes in comparison with lower altitudes. Limited abundance and diversity of Drosophila fruit fly species were found in different geography of Nepal.
