Introduction:Karachi,a city of unique terrain and moderate tropical climate,is home to several mosquito *** geographical distribution and density of these species may vary within the city,owing to their interaction with an ever-increasing population and urban *** a consequence,the prevalence of vector-borne diseases is unpredictable within the geographical limits of Karachi *** this spatiotemporal study,1,156 mosquito samples were collected from 50 study sites with unique ecological characteristics within the city and a taxonomical exercise was conducted to investigate different vector species thriving in different months and seasons of the *** main genera of mosquitoes were identified and categorized using a pictorial key based on the standard guidelines of the Walter Reed Biosystematics Unit,substantiated with ancillary ***:Three important genera were found in Karachi:Anopheles,Aedes and *** subgenera were subsequently identified,based on their susceptibility to major vector-borne *** had the highest concentration of adult mosquitoes,as the colder weather conditions were suitable for *** recorded the lowest number,owing to excessively hot weather when most of the breeding pockets had dried out;less vegetation(in pre-monsoon conditions)prevented mosquito ***:Slum areas showed an abundance of malaria and dengue vectors,owing to poor hygiene conditions caused by open sewage ***,a major precaution is to raise awareness among people about mosquito-borne *** breeding habitats of these vectors should be studied using geospatial technologies to improve spatial and temporal coverage.
