Oxygen consumption of nymphs of Phasganophora capitata (Pictet) (Plecoptera) with respect to body weight and oxygen concentrations

Abstract

A closed respirometer was used for the measurement of respiratory rates [Formula: see text] of nymphs of Phasganophora capitata (Pictet). Nymphs were found to be conformers since they reduced their oxygen consumption rate when the level of dissolved oxygen in the water was reduced.No significant correlation (P > 0.05) was observed between oxygen consumption and body weight. The metabolic rate [Formula: see text] of nymphs increased less than the body weight or mass.
