STUDIES ON THE DIETARY AND ENDOCRINE REGULATION OF AUTOGENOUS REPRODUCTION IN AEDES TAENIORHYNCHUS (WIED.).

Abstract

The expression of autogeny, in a highly autogenous strain of AEDES TAENIORHYNCHUS, may be reduced by altering the quality and quantity of the larval diet and by withholding sugar from newly emerged females. Allatectomy of these autogenous A. taeniorhynchus within one hour of emergence prevented all autogenous yolk deposition, but the implantation, 24 hours later, of 1 pair of corpora allata stimulated egg maturation. Extirpation of the medial neurosecretory cells from the brain of newly emerged ♂ ♂ also prevented autogenous egg maturation.
