The effects of phorate and some of its metabolites incorporated in an artificial diet on liquid uptake by Aphis fabae scop.
[14C]Phorate and some of its metabolites were incorporated in an artificial diet and their effects on liquid uptake by Aphis fabae were studied. At sublethal and very low toxicity levels of phorate there was a tendency for a reduction in feeding with increasing concentrations. [14C]Phorate sulphone, [14C]phorate sulphoxide and [14C]phoratoxon sulphoxide at high concentrations gave very low mortality figures, but a significant drop in liquid uptake occurred with increasing concentrations. The results demonstrate that the presence of the insecticide rendered the diet less acceptable to the aphids which exhibited a wandering behaviour that might promote transmission of virus diseases.[1]References
