Haemolymph Proteins and Yolk Formation in <i>Rhodnius Prolixus</i> Stål

Abstract

ABSTRACT There are two adult-specific proteins in the haemolymph of Rhodnius. They appear to be formed in the fat body. The two proteins are absorbed by the oocytes and form the bulk of the soluble egg proteins. The changes in the concentration of total protein in the haemolymph and of four protein fractions, as separated on cellulose acetate, do not reflect egg production. This may be a consequence of the hormonal control of reproduction.
