But why do these cursed mosquitoes stubbornly spoil our summer evenings? Several explanations have been put forward to explain this renewed nocturnal activity.

[EN VIDÉO] Mosquitoes attracted to the smell of lactic acid in human sweat Mosquitoes have a special olfactory receptor that allows them to detect lactic acid in human sweat. Blocking this receptor could be a new lead for repellents.
Most mosquito species like Aedes Aegypti, Anopheles Where Culex are rather nocturnal: during the day, they protect themselves from heat and sun and only come out at nightfall. A Notre Dame University study thus showed that by exposing mosquitoes to a light white for about ten minutes at the start of the night, the biting rate is considerably reduced. By multiplying these 10-minute “sessions” during the night, it is even possible to almost completely eliminate the risk of being bitten, say the researchers. Conversely, light attracts other insects. Which means that “blue” lights are much more effective at getting rid of moths than mosquitoes.
Smells better perceived in the evening
A previous study from 2013 published in Scientific Reports puts forward another explanation: the mosquito Anopheles gambiaethe species which notably conveys the malaria, would smell human odors better in the evening. This mosquito makes protein who transport the molecules odorous to the olfactory receptors. However, the production peak of these proteins is maximal at dusk and overnight, according to the researchers.
The tiger mosquito bites during the day
However, some mosquitoes are more active during the day, such as the tiger mosquito (Aedes albopictus). Lack of luck, the latter is also more aggressive than the others and he does not make noise when flying. Many other factors influence and attract mosquitoeslike sex, genetic or the color clothes.
