For decades I have heard about how flies and mosquitoes carry diseases around and infect humans and indirectly kill them in mass numbers. Somehow these diseases do not appear to harm these insects, I am not sure why. This brings me to my question, are there no diseases that infect and harm flies and mosquitoes at any stage of their life? Are there really no microbes that are out to kill them? How is this even possible? I have not found anything related to this yet through my google search.
If the flies and mosquitoes are immune to harm from every disease on earth, then why is this so? Certainly we should be able to find out the secret behind this.
