"If infected, however, mosquitos will wait to eat until the parasites developing within the gut mature and migrate to the salivary glands. "It was thought that fasting until malaria could be transmitted was beneficial to the malaria parasite because if the female mosquito was not feeding, she was not being swatted. The return of hunger seemed to correlate with the migration of parasites to the salivary glands. The hungrier the mosquitos are, the more they feed and the more chances to find new hosts.
Cator and colleagues who included Justin George, postdoctoral fellow; Simon Blanford, research associate; Courtney C. Murdock, postdoctoral fellow; Thomas C. Baker, professor of entomology; Andrew F. Read, professor of biology and entomology and alumni professor in biological sciences; and Matthew B. Thomas, professor of entomology, used a mouse model and showed that indeed female mosquitos behaved in this way.
