The protein content of the larval diet was found to significantly influence oocyte production by autogenous females of the pitcher plant mosquito, Wyeomyia smithii. Addition of sucrose to the adult diet of Wy. smithii increased adult longevity and, under the conditions of the test, resulted in significantly increased fecundity. There were no significant changes in fecundity when 10% or 25% concentrations of egg albumin were added to the adult diet. Likewise total amino acid concentrations of 0.37 mg/m 1 and 1.94 mg/m 1 in the diets of adult Wy. smithii females did not increase fecundity.
