Abstract: Mosquito-borne diseases remain one of the most persistent challenges to global public health, particularly in tropical and subtropical regions where climatic and ecological conditions favor mosquito proliferation. Vector mosquitoes, especially species belonging to the genera <em>Anopheles</em>, <em>Aedes</em>, and <em>Culex</em>, play a pivotal role in transmitting pathogens responsible for malaria, dengue, chikungunya, Japanese encephalitis, and lymphatic filariasis. The epidemiology of these vectors is shaped by a combination of biological, environmental, and socio-economic factors, with rainfall patterns, temperature fluctuations, urbanization, and human behavioral practices exerting strong influence on their incidence and distribution. Understanding the seasonal dynamics of vector populations is crucial, as fluctuations in mosquito abundance are directly linked to outbreaks of vector-borne diseases. For instance, the perennial presence of <em>Culex quinquefasciatus</em> sustains a continuous risk of filariasis, while the rapid proliferation of <em>Aedes aegypti</em> during the monsoon season often leads to surges in dengue transmission. At the same time, malaria remains closely tied to <em>Anopheles</em> breeding in specific aquatic habitats shaped by rainfall and agricultural practices. Examining the incidence and epidemiology of these vectors provides not only insights into their ecological adaptations but also highlights the critical need for evidence-based vector surveillance, early-warning systems, and integrated management strategies aimed at reducing the disease burden in vulnerable communities.
