ABSTRACT: A number of dipteran fly species are found in Jeddah with public health and veterinary importance due to their  association with myiasis of livestock and humans. Although several reports are available on the myiasis causing flies from different parts of Saudi Arabia  very little is known  available on prevalence and characterization of these flies from Jeddah Province, which include the major harbour on the Red Sea, western Saudi Arabia and acts the gateway for millions of live animals in the kingdom. Therefore to fill this knowledge gap, the objective of this work is to fill up this gap. For fly survey, the adult flies were collected by the means of Malaise & Bait traps, Yellow traps  and sweeping nets from different marked locations including slaughter houses and live animals farms ( Fig.1). The total number of flies from each locality was counted   and were sorted for taxonomic species identification using specific pictorial keys.In this study, ten dipteran  fly species belonging to six families were identified as causing myiasis on the basis of reported cases in Saudi Arabia. The flies  collected during  the survey were Megaselia scelaris, Musca domestica, Fanniia canicularis, Sarcophaga haemorrhidalis (Bercaea cruentata); Parasarcophaga ruficarnis, Wohlfahrtia nuba , Chrysomya marginalis C. albicep, C.  megacephala, and Oesteris ovis. Among collected flies the  highest number were of  Musca domestica  (67.6%) and the  rest were other species. Most of the species were collected from slaughter houses (50%)  followed by animal farms (39%). The present study identified a number species of myiasis-causing flies of  the public health and veterinary significance, which should inform wider studies on their seasonal abundance, significance and consequent implementation of preventive control measures.
