OCCURRENCE OF AMINO ACIDS IN THE HONEYDEW OF THE CRESCENT-MARKED LILY APHID, <i>MYZUS CIRCUMFLEXUS</i> (BUCK.)

Abstract

The honeydew of Myzus circumflexus feeding on Katahdin potato contains 22 free amino acids and amides, which are given in their respective amounts. Carbohydrates constitute also an important portion of this product of digestion in aphids. Analyses of amino compounds in honeydew may be of prime importance in the study of the causes of plant resistance to aphids.
