Colloque
Since very little work has been done on phosphorous metabolism in Tribolium confusum Duval, except that of Chaudhary and Lemonde on total phosphorous and acid-soluble phosphorous, a more detailed investigation on phosphorous metabolism particularly with respect to ATP contents and ATPase activities at the different stages of development and growth of the insect was undertaken. The ATP content, as expected varies inversely to the ATPase activity at all stages of growth and development of the insect. The significance of ATP content and ATPase activity in regulating all the energy requiring synthetic processes of life in Tribolium confusum will be discussed.
Colloque
Devi, Lemonde and Sarkar on the basis of their work in this laboratory on the variations of nucleic acids and total nucleotide contents in Tribolium confusum Duval, in the course of development and growth, suggested the presence of a polyphenolic compound or compounds in pupae and adult insects and responsible for pigmentation of the skin of the adult insect. In order to identify the compound chemically it was extracted with water from adult insects. From chemical analysis it appeared that the lyophilized material contained aromatic compounds with free hydroxyl groups in the ring and from chromatographic analysis it was concluded …
