After the bird cherry-oat aphid infestation a clear decrease in the content of water, free protein amino acids, sucrose and cyanogenic glycosides as well as cyanogenesis potential within the infested bird cherry leaves was...
Changes in activity of detoxifying enzymes, involved in metabolism of glutathione in bird cherry-oat aphid during its host alternation have been investigated.
