Scientists have discovered the mystery behind the fact that why mosquitoes bite some people more than the other. It is said that mosquitoes use three organs to smell and taste- a feathery antenna which can identify a wide range of different chemicals, a proboscis used for short-range detection and the maxillary palp for longer range smelling. The maxillary palp contains a series of highly specialized receptor cells used to detect the different components of human body odour. To the mosquitoes some people’s sweat smells better than others because of the proportion of carbon dioxide, octenol and other compounds that make up the body odour. It is those people who are more bitten than others.
