Abstract
Mosquitoes of the genera Anopheles, Culex, and Aedes are of major medical importance as vectors of malaria, filariasis, Japanese encephalitis, dengue, chikungunya, and Zika. Understanding their morphology and bionomics is fundamental for vector biology, ecological studies, and the design of effective control strategies. Laboratory colonies of mosquitoes serve as an indispensable resource for investigating mosquito genetics, physiology, and vector–pathogen interactions, while also enabling the evaluation of new interventions such as Wolbachia-based control and the sterile insect technique. This review synthesizes current knowledge on the morphology and bionomics of key mosquito vectors and outlines advances in colony establishment, rearing, and maintenance. Particular attention is given to larval and adult diet, environmental conditions, oviposition, blood-feeding methods, and strategies to minimize inbreeding and maintain microbial balance in colonies. Challenges including genetic drift, colony adaptation, and maintenance of representative field traits are discussed alongside emerging solutions. By integrating classical entomological knowledge with recent innovations in rearing technology, this review highlights the central role of sustainable mosquito colonies in strengthening basic research and supporting applied approaches for vector-borne disease control.
