Several chapters focus on flies and mosquitoes, detailing mosquito biology and the experimental evidence linking mosquitoes to malaria and yellow fever. It treats fleas and plague and outlines practical control measures including sanitation, habitat modification, natural enemies, and community or regulatory actions. Photographic illustrations accompany many descriptions to show insects as observed in field and laboratory.
