@Pamela Rosa,
Maybe Bill was gonna use the demonstration to let the guys in the audience know that only Anopheles mosquitoes carry Plasmodium vivax, falciparum, malariiae, and ovale (all the four species of Plasmodium are malaria causers and each presents a different form of malaria). WE have other diseases caried by other mosquito species and the chances of our own mosquitoes carrying malaria are quite remote in the PAcific Northwest. Id be more concerened about peanut butter in my snacks
