Hemocoel infusion of an amino acid mixture at a concentration of 7.5% and 10% (wt:vol) for 24 h rarely activated ovarian development in either mated or unmated females of Anopheles stephensi Liston. Infusion of either concentration mixture for 48 h into unmated females was also scarcely stimulatory, but the same 48 h infusion into mated females resulted in ovarian maturation in 25% (7.5% mixture) or in 78% (10% mixture) of the infused specimens. Similarly, feeding on an amino acid mixture (7.5%) containing sugar induced 44% ovarian maturation among mated females, while only 3% of unmated females showed matured oocytes. The increase of hemolymph amino acid concentration levels may be one of the essential factors for oogenesis of An. stephensi, and mating enhances ovarian development, especially in females ingesting poor meals. However, some additional factor(s) may be included for full development comparable to that induced by blood meals.
