Abstract

Fast chlorophyll fluorescence kinetics are shown to be an early indicator of plant stress caused by aphid feeding. We report results for barley infested with Sitobion nr fragariae and for susceptible and resistant lucerne cultivars infested with spotted alfalfa aphid Therioaphis trifolii (Monell) f. maculata and pea aphid Acyrthosiphon pisum (Harris). The method has potential in rapid assessment of plant susceptibility or resistance, and of aphid phytotoxicity, and may be equally applicable to studies of plant stress caused by other sucking insects, by mites and by plant pathogens.
