Influence of the amino acid balance on the improvement of an artificial diet for a biotype of Acyrthosiphon pisum (Homoptera: Aphididae)

摘要: A green biotype of the pea aphid, A. pisum, from Lusignan (France), showed very poor performance on standard Akey and Beck diet. Significant improvement occurred after reduction osmotic pressure diet modification amino acid component, according to results carcass analysis. further was obtained through an optimalization aromatic level: tyrosine deficiency induced by its solubility overcome excess phenylalanine inclusion a soluble compound, β-alanyltyrosine. new therefore formulated for this biotype, which adults were more than twice as heavy
