| Abstract: | ABSTRACT. The ecdysteroid titre of adult females resulting from a cross of Aedes epactius females, an anautogenous mosquito, with Aedes atropalpus males (an autogenous strain) was determined using a radioimmunoassay. The F1 hybrid is autogenous and produces mature oocytes without the benefit of a blood-meal. The ecdysteroid profile of this hybrid revealed a smaller early peak and a second larger one. Qualitatively the overall hormonal profile appeared quite similar to the ones previously obtained using A.atropalpus females and blood-fed A.aegypti. Quantitatively, the amount of endogenous hormone exhibited, and the total number of mature oocytes produced, may be positively correlated. |
