Effect of phenolics on the pea aphid, Acyrthosiphon pisum (Harris) population on Pisum sativum L. (Fabaceae).

摘要

Phenolic compounds with insecticidal properties were studied in pea (cv. Tulipan) plants infested by A. pisum. Six flavonol aglycones were identified in pea: quercetin, kaempferol + RCO-, kaempferol, tricin, apigenin + RCO-, and apigenin. In infested plants, concentrations of total phenols, o-dihydroxyphenols and total flavonoids were higher than in the control plants (not infested). The phenolic compounds had negative effects on insects; thus, these compounds may be used for the control of insect pests.
