The present study deals with the oral supplementation with (50, 100 and 150 ?g/ml) synergetic effect of potassium and magnesium chloride on the fat body glycogen, protein, total lipids and haemolymph trehalose, protein of fifth instar larvae of Bombyx mori L (Lepidoptera: Bombycidae). The observed parameters significantly increased in all the treated groups when compared with those of the corresponding parameters of the carrier control. These results may suggest that the minerals may stimulate the enzyme activity which influences the metabolic process thereby increasing the biochemical contents of the fat body and haemolymph of the silkworm, B. mori L.
