The Influence of Phenolic Compounds on the Preference of Winter Wheat Cultivars by Cereal Aphids
The effect of phenolic compounds on the preference for winter wheat cultivars as hosts by cereal aphids and the effect of the phenolics, reported in the leaves of cereals, on feeding intensity of Rhopalosiphum padi (L.) larvae was investigated. Preference for the studied winter wheat cultivars was associated with the level of phenolic compounds naturally occurring in the plants. The tested dihydroxy-phenols showed highest inhibition of the feeding of R. padi larvae.
