title: Studies on the proteins of Poekilocerus pictus. III-changes taking place in the haemolymph protein during maturation of male.
abstract: In all 7 protein fractions have been detected in the haemolymph of Poekilocerus pictus by the Polyacrylamide gel disc electrophoresis. Out of seven protein fractions, four fractions i.e. 3, 4, 5 and 6 take major role in the maturation of testis. Accumulation of proteins has been observed in the castrated insect. The concentration of the protein decreases and the size of the testis follicle remains small as compared to the normal male in the allatectomised insect. It is concluded that the proteins are selectively incorporated in the testis. It also appears that the synthesis of proteins and the maturation of testis is controlled by the allatum.
