[Age-related changes of the mineral component content in the hemolymph of 2d- and 3d-stage larvae of the reindeer warble fly (Hypodermatidae)].

A mineral components concentration in the haemolymph of the IInd- and IIIrd-stage larvae of Oedemagena tarandi depends on the physiological state of parasites. Metabolism of mineral components is most intensive in a young actively growing organism and during moulting. The moulting is characterized by the decrease in the concentration of inorganic phosphorus and potassium and by the increase of calcium, magnesium and natrium.
