Mosquitoes of the genus Anopheles, which transmit malarial parasites, differ from the common Culex in every stage. When at rest the adult Culex holds its body parallel to the surface, whereas Anopheles holds it nearly perpendicular. then a long series of studies by various investigators, among whom Grassi stands foremost, showed that when a mosquito of the genus Anopheles bites a malarial patient, it secures with the blood some of the parasites such as Laveran had discovered, and thereupon the mosquito becomes the host of the Malarial organism. Within the mosquito, the parasite undergoes a complicated series of changes, including rapid reproduction, This finally results in myri- ads of parasites located in the sali v^ary glands of the insect, ready to be injected into the blood of the next individual bitten and to begin the other phase of its life history in Man. (Fig. 223.) So stated, it appears simple enough, but years of study by spe- cialists on Insects (entomologists), by specialists on Protozoa.
