The respiration rate of the beet armyworm pupae (Spodoptera exigua) after multi-generation intoxication with cadmium and zinc.
The beet armyworm (Spodoptera exigua) were fed on artificial food contaminated with zinc (200 mg kg(-1) dry mass) or cadmium (66 mg kg(-1) dry mass) for 15 generations. In 15th generation, O2 output and CO2 production of pupae were measured. Exposure to cadmium did not cause any effects whilst exposure to zinc led to a significant increase in the respiration rate of pupae. The average respiratory quotient (RQ) did not differ between treatments (ca. 0.7).
