The present study was undertaken to understand the effect of high temperature as well as low temperature on the haemolymph organic components of the male millipede M. importatus. The observations show that exposure of millipedes to high and low temperature affects the haemolymph organic components. After exposure to high temperature the haemolymph total proteins, total carbohydrates and total lipids show gradual decrease. And after exposure to low temperature the concentration of these components show gradual increase
