Spatial Dispersion and entomological survillance of Mosquito Species in the point of entry of Western Tehran , Capital of Iran

Background: Entomological survillance is important due to present and density of the different mosquito species. This investigation help us to determine the behaviour of the vectors of malaria, Dengue Fever, Chickengunia and Zika ViusObjectives: The objective of this study was to monitoring the presence of Aedes mosquito s species at the points of entry of western Tehran city.Materials and Methods: This study was carried out from March 2018 until late September 2019 after selecting fixed sampling sites including: Tehran Pars Bus station (35°43 21.77 N, 51°31 7.04 E), Lavasan (35492882° N, 51375999° E) and Flower Market Mahallati (35°39 40.39 ° N51°28 36.26 ° E) and Sohanak. (35°47 56.51 N, 51°31 55.24 E). The location coordinates of the sampling sites were mark and registered with Global Positioning System (GPS) device, then the digital maps of the high risk areas were drawn using Arc Map 10.5 software. In this study, mosquito s larvae and pupae were collected from larval habitats and 60 standard ovitraps, and reared in Aedes insectary, Medical Entomlogy and vector control, School of Public Health and Tehran University of Medical Sciences. Then they were mounted and identified using different morphological characteristic via systematic keys Results: Generally, 1369 larvae and adults were identified comprises; Culex pipiens Linnaeus, Cx. theileri Theobald and Culiseta longiareolata Macquart, Culex pipiens with 82% was the most abundant species.Conclusion: This is the first modelling study in western Tehran for predicting areas with the possible presence of Aedes species. A modelling study by using geographic information system are suggested in other neighboring provinces of Tehran
