  • Title: Relation between corpus allatum and haemolymph proteins in Sphaerodema rusticum Fabr.
    Author: Shukla RN, Pathak SC.
    Journal: Z Mikrosk Anat Forsch; 1976; 90(3):427-34. PubMed ID: 1031506.
    Abstract:
    The active and inactive stages of the corpora allata have been described on the basis of size and nucleo-cytoplasmic ratio. The polyacrylamide gel disc electrophoresis of the haemolymph has been done in the males and different stages of reproducing females. A protein fraction with a value 14 less than or equal to Rm less than 16 has been observed only in females. Out of 8 protein fractions, 5 showed oscillations in their concentration at the time of vitellogenesis. Finally active stages in the corpora allata are correlated with the fluctuations in haemolymph protein concentration.
