Intensive and extensive sample collection and field survey were conducted to study the density and seasonal distribution of Culex quinquefasciatus for the first time in the rural area around the Rajkot City. Species Identification, larval Density, Adult Density and Distribution of Breeding Sites of the species were studied in the seven villages around the Rajkot City area. Results show that density of adult Culex quinquefasciatus was recorded maximum in the month of September which was the pick month of monsoon in this region and lowest density found during the month of May which was pick summer in the study area. Furthermore, breeding sites of the Culex quinquefasciatus were also recorded more in the monsoon and post monsoon season. Therefore it was clearly indicate that the temperature, rainfall and humidity play major role in the density and distribution of Culex quinquefasciatus.
