ABSTRACT
The present study focused on dipterous flies distribution and densities in 14 Egyptian governorates. The abundance and distribution of flies was carried out in three phases. The first was in 1999 in 5 governorates [Qalyoubia, Monoufia, Fayoum, Behaira and Assiut] including species of the families: Calliphoridae, Chloropidae, Drosophilidae, Milichiidae, Muscidae, Otitidae, Piophilidae, Sarcophagidae, Sepsidae, Sphaeroceridae and Syrphidae. The second was in 2000 in another five governorates [Kafr-El-Sheikh, Giza, Menia, Aswan and Sharqia] including. of the families: Calliphoridae, Chloropidae, Drosophilidae, Milichiidae, Muscidae, Otitidae, Piophilidae, Sarcophagidae, Sepsidae, Sphaeroceridae and Syrphidae. The third phase was in 2001 in 4 governorates [Qena, El-Wady El-Gedied, Daqahlia and South Sinai] including species of the families: Calliphoridae, Chloropidae, Drosophilidae, Milichiidae, Muscidae, Otitidae, Phoridae, Piophilidae, Sarcophagidae, Sepsidae, Sphaeroceridae and Syrphidae. Musca domestica was the most abundant sp. found throughout the work. The results are a step in drawing an update map for insect-vectors to help in the national controls programs
