A human's unique body odour indicates that the target is actually a human host rather than some other living warm-blooded animal (as the presence of CO 2 shows). Body odour, composed of volatile organic compounds emitted from the skin of humans, is the most important cue used by mosquitoes. [ 42 ]
In January 2024, a publication by an Australian research group demonstrated significant genetic similarity between Mycobacterium ulcerans in humans and possums, compared to PCR screening of M. ulcerans from trapped Aedes notoscriptus mosquitoes, and concluded that Mycobacterium ulcerans, the causative pathogen of Buruli ulcer, is transmitted by mosquitos.
Mosquito control is a vital public-health practice throughout the world and especially in the tropics because mosquitoes spread many diseases, such as malaria and the Zika virus. Mosquito-control operations are targeted to multiple problems: Nuisance mosquitoes bother people around homes or in parks and recreational areas;
Concern about a human-caused Holocene extinction has been growing since the late 20th century, although much of the early concern was not focused on insects. In a report on the world's invertebrates , the Zoological Society of London suggested in 2012 that insect populations were in decline globally, affecting pollination and food supplies for ...
Smells produced by humans are a big part of what draws mosquitoes to us. In a study, scientists helped pinpoint the chemicals in body odor that attract the insects. What mosquitoes are most ...

The vast majority have been Culex mosquitoes, a primary vector for West Nile virus. But another mosquito species that does not carry the virus, Aedes aegypti, has also become more common in Las Vegas.
Vectors are living organisms that pass disease between humans or from animal to human. The vector carrying the highest number of diseases is the mosquito, which is responsible for the tropical diseases dengue and malaria. [17] Many different approaches have been taken to treat and prevent these diseases.
