ABSTRACT
The concentrations of Na+ and K+ in the haemolymph remain relatively constant during the moulting cycle.
Desiccation, desiccation followed by rehydration and starvation exert little or no effect on the concentrations of Na+ and K+ in the haemolymph.
The volume of haemolymph decreases during desiccation and increases after rehydration.
More Na+ is voided in the excreta during desiccation.
Repeated desiccation and rehydration causes the loss of both Na+ and K+ from the body.
The effects of desiccation and rehydration on the concentrations of chlorides and free amino acids in the haemolymph are described.
