Bradley Fikes of the San Diego Union~Tribune writes about the controversial topic of sterilizing female Anopheles gambiae mosquitoes to inhibit the transmission of malaria. Mike Kalichman, Director of the Ethics Center and UC San Diego’s Research Ethics Program, shares, “The population genetics here get very interesting, in part because if it’s only female mosquitoes that feed from humans and other animals,” Kalichman said by email. “In any case, the net effect remains either an eventual elimination or severe restriction of the mosquito population.”
