ABSTRACT
Mosquito borne infection is considered a most important public health problem all over the world including the dengue virus. The dominant occurrence of Aedes mosquitoes under the influence of environmental factors (temperature, relative humidity, and rainfall) of Multan city was assessed during 2014-2016. In this study, Aedes larvae were collected by using the entomological dipping method and identified in the laboratory. The results showed mean (±SD) temperature, rainfall, and relative humidity during 2014-2016 ranged 12.88-35.43oC, -0.33-87.43mm, and 36.17-72.17%, respectively. Likewise, maximum Aedes larvae were found during the month of November, with 348.67 Aedes larvae from indoor while 71.67 from outdoor. The emergence of Aedes larvae was found after rainy season while decline trend was observed at non-rainy, extreme temperatures and relative humidity conditions. This study could be used in further studies in order to evaluate Aedes mosquito emergence in relation with different environmental variables, and to establish integrated vector control strategies in the future.
