Spatial Distribution of Necrophagous Flies of Infraorder Muscomorpha in Iran Using Geographical Information System.

Medically important flies that majority of them are classified to synanthropic flies can be mechanical vectors for some of contagious diseases to human and many animals. Also some species of their larvae are cause of myiasis in human and livestock animals. The aim of this study was to determine the geographical distribution of medically important flies in Iran using Geographical Information System (GIS). All published English and Persian documents on medically important flies of Iran from reliable medical sciences resources were gathered. A database was then designed in Excel format, including all available information regarding flies. The valid data were transferred to ArcGIS 10.3 to prepare the first spatial database of medically important flies and human myiasis foci of Iran. The Iran Medical Important Flies base includes 71 papers and three PhD/MSc theses, reporting studies conducted during 1977-2017. This database contains different available data covering their faunistic and all myiasis data reports related to flies of 102 species in nine families of medical important flies in Iran. Twenty-three out of the 31 provinces of Iran, had some reports of medically important flies. However, these flies have high species diversity, wide geographical distribution and with various ecological niches in different provinces in Iran. Besides that, there are many high-risk foci of human myiasis in a number of provinces of Iran.
