Can mosquito perceive a new born baby

What an interesting question!

Mosquitoes have a unique sense of smell and can detect certain chemicals, such as lactic acid, carbon dioxide, and other volatile organic compounds (VOCs), which are emitted by humans. These chemicals help mosquitoes locate their hosts and detect potential mates.

Newborn babies, however, have a different scent profile compared to adults. Newborns have a unique combination of chemicals on their skin, which is influenced by their mother's hormones and the environment they were born into. This scent profile is often referred to as the "newborn scent" or "neonatal scent."

Research suggests that mosquitoes can detect the scent of newborn babies, but their ability to do so is limited. A study published in the Journal of Insect Physiology found that mosquitoes were attracted to the scent of newborn babies, but the attraction was weaker compared to the scent of adult humans.

There are a few reasons why mosquitoes might be less attracted to newborns:

  1. Different scent profile: Newborns have a unique scent profile that is distinct from adults. Mosquitoes may not be as familiar with this scent, which could make it less attractive to them.
  2. Lower levels of lactic acid: Newborns have lower levels of lactic acid on their skin compared to adults. Lactic acid is a chemical that mosquitoes use to detect their hosts, so the lower levels in newborns might make them less attractive to mosquitoes.
  3. Other factors: Newborns are often swaddled or wrapped in blankets, which can reduce the amount of scent they emit. Additionally, newborns are often in a warm, humid environment, which can also affect the way their scent is perceived by mosquitoes.

It's worth noting that while mosquitoes might be less attracted to newborns, they can still bite them. However, the risk of mosquito-borne diseases, such as malaria or Zika virus, is generally lower in newborns compared to adults.

In summary, while mosquitoes can detect the scent of newborn babies, their ability to do so is limited compared to adults. The unique scent profile of newborns, lower levels of lactic acid, and other factors might contribute to this reduced attraction.
