Abstract
The early literature on Phlebotomus sandflies contains several references to the necessity of a blood meal for ovarian development and oviposition. Smith (1925) and Christophers et al (1926) working with P. argentipes, Adler & Theodor (1935) working with P. perniciosus, and Ashner (1927), Theodor (1934) and Unsworth & Gordon (1946) rearing P. papatasi, all observed egglaying only after prior ingestion of blood. Autogeny in sandflies was first reported by Dolmatova (1946). She found that P. papatasi from eastern Georgia, U.S.S.R., possessed the autogenic trait, but that specimens of the same species from Tadijikistan did not. Subsequently, Hertig et al (1960) and Johnson (1961) demonstrated autogenic development of Panamanian P. gomezi, P. panamensis and P. sanguinarius.
