Background & aim:  Flies are important in the region in terms of mechanical transmission of pathogens, sciatica and forensic entomological research. Identification of species in different regions is the first and most important way to control vector-borne diseases in the region. Therefore, the aim of the present study was to determine the diversity of species and relative abundance of flies of medical importance in Golestan province during 2018-2019.
 
Methods: In the present descriptive study, the samples included medically important flies, which were sampled in both urban and rural areas, including eight stations in Ramyan city in 2018. Trapping was done monthly, on sunny days and on the hottest day of the month. Entomological nets and cone traps were used to catch adult flies. Species identification was performed based on valid keys. The collected data were analyzed using Microsoft Excel software.
 
Results: In the present study, 10 species of Musca domestica (housefly) (53.75), Muscina stabulans (7.26), Lucilia ceasar (14.39), Lucilia sericata (7.91), Calliphora  vicina (8.95), Sarcophaga africa (1.55), Sarcophaga aegyptica (0.51), Calliphora vomitoria (3.48), Sarcophaga argyrostoma (0.75), Muscina levida (0.18) in three family including Muscovidae, Sarcophagidae and Acrostida were captured. The most abundance of flies were observed in garbage collection sites and animal places. Musina levida species was reported for the first time from northern Iran in this study. Based on the results of temperature and humidity fluctuations, it was established that the higher temperature and decreasing humidity, the more abundance of flies’ population were obsereved.
 
Conclusion: Due to the high abundance of flies in waste collection sites and animal sites, rapid transfer of non-residential areas and their sanitary burial is necessary to reduce the population of flies. It is necessary to move animals out of residential areas and provide health advice to people and health centers on diseases transmitted by flies in the warmer months of the year.

Background & aim: Due to their close connection with humans, flies are able to mechanically transmit many pathogenic agents and thus cause various diseases. Knowing and determining the species of flies is necessary to know the current situation and plan for their control. Therefore, the purpose of the present study was to determine and investigate the species diversity and relative abundance of medically important flies in Fouladshahr, Isfahan province.

Methods: The present study was of a descriptive-analytical type. Sampling was done from April to March 2018 for one year and twice a month in selected stations in Fouladshahr, Iran. The collection of adult flies was done using insect nets and using inverted cone plastic bottles traps. In order to try to obtain the maximum diversity of species, sampling was done in four seasons and six times in each season, twice a month and once in each region. The sampling location was selected based on the proximity to the places where flies grow and develop, such as around the hospital, garbage collection, health and treatment centers, and animal places with the possibility of flies. Daily average temperature, humidity and wind speed were recorded. After catching the flies, they were transported to the laboratory and mounted. A that point they were identified using a valid identification key. The collected data were analyzed using Spearman's correlation and GEE regression statistical tests.

Results: In the present study, 6030 flies from three species, Musidae, Calliphoridae and Sarcophagidae, were caught. The highest number of flies belonged to the species Musca domestica (72%) and Sarcophaga aegypti (0.08%) had the lowest frequency. The highest abundance of flies was in the month of July and the lowest amount was respectively in the months of January and February in Fouladshahr. Correlation results indicated that with the decrease in humidity, the population of flies increased (P˂0.004) and with the increase in temperature, the abundance of flies increased (P˂0.0001).

Conclusion: Considering the abundance of flies and their health importance in the study area, it seems necessary to adopt appropriate methods to manage resources and use existing capacities to control the population of flies in the study area.
