Catabolic substrate utilization patterns: varying humidity and dietary regimens in the American cockroach Periplaneta americana (L.) (Dictyoptera: Blattidae)
Changes in metabolic substrate utilization patterns resulting from exposure to varying humidity and dietary regimens were examined in the adult, male American cockroach. A series of respirometric experiments were conducted to monitor changes in respiratory quotient (RQ), oxygen quotient (QO₂), food …
