Impact of Starvation on Worms and ionic composition of Haemolymph of Philosamia Ricini

ABSTRACT

The fifth instar larvae of Philosamia ricini were reared under food stress. These were kept on starvation for three days. After that the haemolymph was taken for the analysis. Monovalent cations sodium, potassium and divalent cations calcium and magnesium were estimated, to observe the impact of starvation. With respect to ther control worms Na+ ions increased significantly while Mg++ ions showed rather insignificant change. Divalent cation Calcium showed an insignificant change but Magnesium ions showed a significant decrease.

KEYWORDS: Haemolymph, monovalent cation, divalent cation, starvation,
