Autogeny was demonstrated by newly emerged adults of Culicoides furens (Poey), C. hollensis (Melander & Brues) and C. melleus (Coquillett) collected from coastal salt marsh and tidal creek areas of North Carolina. This is the first demonstration of autogeny in a population of C. hollensis. The mean number of eggs laid on agar or moist filter paper by adults (fed only on a 10% sucrose solution) held individually at 20-220C and 85-90% RH under natural lighting were: C. furens 39.9 (+ 23.5), C. hollensis 54.0; (+ 382.) and C. melleus 77.7% for C. hollensis and 45.5% for C. furens. About 15% of the C. furens, 13% of the C. hollensis and 0.3% of the C. melleus were reared to the adult stage from eggs laid autogenously on agar medium supplied with live nematodes as food for the larval stages.
