With the initial bite to an individual, there is no reaction, but with subsequent bites, the body's immune system develops antibodies. The bites ...
Understanding the specific chemicals that attract mosquitoes facilitates the development of innovative control strategies. For example, mosquito traps that emit both CO2 and lactic acid have proven more effective in luring mosquitoes away from human populations, significantly reducing the risk of bites and the spread of diseases.
