THE Energetics and growth efficiency of aphis fabae scop. reared on different parts of the broad bean plant (vicia faba)
1978
Apterous virginoparae of A. fabae were reared on four different parts of broad bean seedlings. The energy channeled into larval growth, exuvia, adult reproduction and excretion was measured throughout the aphid's life. The greatest differences in the energy budgets were during reproductive life when aphids living on young stems fed at a much greater rate and were more fecund than those living on mature stems: There were also considerable differences in energy utilization of aphids reared on young plant growth and mature plant growth but there were few differences between stem and leaf dwellers.
