Mosquitoes are among the most efficient vectors of infectious diseases, with their ability to detect hosts from a distance playing a crucial role in disease transmission. Central to this process are olfactory and gustatory receptors, which are vital components of the mosquito chemosensory system. This study aims to investigate the structures and functions of these receptors, focusing on their role in detecting and responding to volatile compounds emitted by potential hosts. By elucidating the molecular mechanisms underlying mosquito host preferences, particularly those governed by olfactory detection, we aim to advance the understanding of mosquito behaviour and sensory biology. Through this research, we seek to identify chemosensory receptor structures, characterize their functional dynamics, and explore their potential as targets for novel vector control strategies. The findings of this study are expected to contribute to the development of more effective and environmentally sustainable methods for reducing mosquito-borne disease transmission.
