An energy budget was constructed for A. fabae reared on synthetic diets and compared with that published for aphids living on broad bean. Larval aphids living on broad bean utilized 54% of their energy intake for growth, 4% was lost during respiration and 42% was excreted as honeydew. Aphids living on a synthetic diet utilized 26% of their energy intake for growth and 4% was lost during excretion. 76% was excreted as honeydew. The growth efficiency on a synthetic diet was 20% compared with a value of 50% on plants. The value of synthetic diet experiments in furthering our understanding of aphid nutrition is discussed in the light of these results.
