Female Mosquitoes Track to the Hosts by the Blue

Abstract

Mosquitoes are the most harmful animals. Annually, they cause illnesses and deaths equivalent to the entire global COVID-19 pandemic over three years^[1][2][3]. They are not naturally born with disease-causing pathogens but acquire them from infected individuals and then transmit them to the healthy population through their bites. Their ultimate hosts are those who carry blood, a water solution beneath their skin, a natural membrane that allows water vapor to leak out and their needle to access the liquid. Water vapors are theoretically visible because water molecules are known to naturally reflect blue^[4] and absorb others, making it appear blue. This study investigates the reactions of female mosquitoes when blueness variable is added to the mosquito luring equation by amplifying the reflective the blueness variable of water vapor. This is done by adding more blue photons for them to reflect, increasing their visibility. The search for visible signs of water vapor is the top priority for these insects when they identify and target their hosts from afar, as they selectively respond to this over other mosquito attractants.
