Abstract
Total protein, lipid, and glycogen of Aedes vexans (Meigen) were related li nearly to body size at eclosion. Starvation after emergence led to the dete rmination of minimal irreducible amounts of protein, lipid, and glycogen an d the availability of the teneral reserves, whereas access to sucrose revea led the potential for reserve synthesis. Glycogenesis and lipogenesis incre ased reserves approximate to 10-fold the teneral value within 1 and 2 wk af ter emergence, respectively. Carbohydrate feeding was an essential behavior before blood feeding and oogenesis commenced. Female night was tested on a flight mill. Maximal flights of 10-17 km in a single night occurred at 2 w k posteclosion and paralleled maximal reserve syntheses. Comparisons of our laboratory data to host-seeking mosquitoes in the field confirmed our data . The vast majority of maternal lipid was transfer red to the yolk when a b lood. meal was taken, but only a quarter of the blood protein was recovered fi om mature ovaries. Maternal glycogen was used mainly for flight. Fecund ity varied between 20 and 120 eggs per female and was determined largely by body size and blood meal volume. At 27 degreesC, maximal egg numbers were produced, but at 22 and 17 degreesC the caloric yolk content was greater. F emales from the southern United. States were smaller than females from nort hern areas. However, southern females had similar fecundity as northern fem ales, and their flight performances were similar. Differences in tile repro ductive physiology between this species and Ac, aegypti were discussed.
