[Dynamics of nitrogen-containing compounds in the hemolymph of 2d- and 3d-stage larvae of the reindeer warblefly (Hypodermatidae)].

The content of the total protein, residual and amine nitrogen, urea and ammoniac depends on the physiological state of the warble fly larvae of the reindeer. Metabolism of nitrogen-containing compounds carries out most intensively in the growing organism and during the moulting period. The moulting period is characterized by the fall in the total protein, residual and amine nitrogen and increase of the ammonias and urea.
