The Storage of Protein, Fat, Glycogen and Uric Acid in the Fat Body and Other Tissues of Mosquito Larvae

IT is generally agreed that the main function of the fat body of insects is the storage of those reserve substances which require rapid mobilization during moulting and metamorphosis. But little attention has been given to the part taken by other organs and tissues in building up reserves and almost none to the influence of the composition of the food upon the type of reserve substance laid down. These problems form the subject of the present paper. Mosquito larvae have been starved until all their reserves have been consumed. They have then been fed upon single substances and the storage of protein, fat and glycogen in the various tissues observed.
