Laboratory-reared mosquitoes were fed human blood alone or sugar plus human blood and assayed at 4, 12, 24, and 48 h after the blood meal. Starved and well-fed mosquitoes were obtained by holding teneral females (≤1 d old) with 0, 5, 10, and 15% sucrose solutions ad libidum from emergence. Both small and large mosquitoes increased their glycogen and sugar levels significantly by feeding on blood only or on blood plus sugar when they imbibed a human blood meal on day 2 after emergence. Mosquitoes only fed blood on day 2 had the highest lipid levels of any treatment group. Both size classes and all feeding regimes failed to increase the total amount of glycogen, lipid, or sugar when they fed on blood 5 d after emergence. We conclude that there is an energetic advantage to Ae. aegypti when they feed on blood early in adult life (≤day 2 after emergence).Mahidol UniversityAgricultural and Biological SciencesImmunology and MicrobiologyMedicineVeterinaryArticleSCOPUS10.1093/jmedent/36.1.13
