A comparison of the excretion rates of Aphis fabae on artificial diet and on bean plants

The performance of Aphis fabae on an artificial diet was assessed by comparing the aphid's excretion rate on the diet with that on bean plants to investigate the possibility of using this diet in toxicological studies. No significant difference was found in the rates of honeydew excretion, but the diet-fed aphids were noticeably smaller than those fed on beans.
