Mineral oil sprays applied to plants or to artificial membranes were assessed for their effect on virus and helper component (HC), both of which are required for aphid transmission. Probing oil-treated surfaces prior to or after probing a virus-HC mixture, HC, or virus, reduced or abolished transmission. Oil also inhibited transmission when contacted after aphids had penetrated membranes which contained a virus + HC mixture. Oil had no apparent effect on aphid probing behaviour. The data support the hypothesis that oil affects the interaction of virus and HC with aphid mouthparts or alimentary tract
