ABSTRACT



The activity of beta-cyanoalanine synthase and rhodanese within the tissues of the three generations of the bird cherry-oat aphid that are specialized to feed on the cyanogenic spring foliage of bird cherry was assessed. The order of beta-cyanoalanine synthase activity in the three aphid generations was: generation 1> generation 2> generation 3; whereas that of rhodanese was: generation 3> generation 1>generation 2. The possible role of the bird cherry – oat aphid enzymes in metabolizing dietary cyanide is discussed.

Key words: beta-cyanoalanine synthase, rhodanese, cyanide detoxication, bird cherry-oat aphid, Rhopalosiphum padi, bird cherry, Prunus padus.
