Zusammenfassung: 
1. Recording of cyclic CO2 release in insects (Periplaneta americana) in voluntary immobility resolves the regular constriction-flutter-ventilation (CFV) cycles at true standard metabolic rate (SMR). 2. Both can be used as a reference for very sensitive recordings of sublethal effects of normal (e.g. desiccation) and anthropogenic (e.g. pollutants) stressors on the SMR, the CFV cycles, and on the induced intra-cyclic (INCA) and extra-cyclic activity (EXCA) which interrupts the resting state. Normal and induced INCA and EXCA patterns can be identified as behavior and quantified by their metabolism. 3. Lethal effects of stressors (desiccation and toxicants) are characterized by loss of CFV cycles and a subsequent irreversible excitation phase.
