Abstract

According to M. W. Service (1978), prior to Patrick Manson’s (1844–1922) discovery in 1877 that the mosquito Culex fatigans (Diptera: Culicidae) was the intermediate host of Bancroftian filariasis, the association of insects with disease and the nature of disease transmission was almost entirely speculation. As biographers P. H. Manson-Bahr and A. Alcock (1927) put it: “Manson’s investigations were thus the first convincing evidence that the vague beliefs traditional among many untutored races and countenanced from time to time by a few sagacious medical men—beliefs that various specific diseases of the blood are disseminated by bloodsucking insects—were of good pathological report and worthy of further thought” ..
