INFLUENCE OF LARVAL NUTRITION ON PHYSIOLOGY OF PROPAGATION OF VARIOUS MOSQUITOES

Abstract

Experiments with C. pipiens and fatigans, stegomyia fasciata and anopheles maculipennis messeae indicated that raising of the larvae with a purely animal feed (blood and calves liver) as compared to a primarily animal (sic) feed (infusion of hay) has a positive influence on the size of the imagoes and increases their vitality. Continuation of this larval nutrition produced manifestations of degeneration in subsequent generations of C. pipiens which disappeared again on feeding with infusion of hay. Autogenous propagation is favored in C. pipiens by feeding the larvae with liver. In the other mosquitoes examined, the influence of the larval nutrition produces the beginning of ovarian development with egg development and yolk deposition without prior blood meal.
