“…Each plant was sprayed for approximately 2s at a distance of 30 cm. Plants which had been oil coated were then left overnight (24-32h) before use in virus transmission experiments, enabling the oil droplets to form a continuous film (Kulps, 1969;Gibson et al, 1988).…”

Mineral oil sprayed onto potato virus Y (PVY) infected tobacco plants reduced acquisition of this potyvirus by Myzus persicae (Sulz.). Although the pre‐penetration activities of aphids were longer on oil treated leaves, the inhibitory effect of the oil could not be attributed to differences in the duration of stylet penetration. Aphids were therefore made part of a DC circuit in order to investigate their stylet activities during penetration of PVY infected source plants and healthy test plants. Both acquisition and inoculation of the virus were reduced by the presence of oil on the plant surface, but these reductions could not be related to electrically recorded differences in plant penetration behaviour. In particular, stylet punctures of plant cell membranes were not reduced by mineral oil. Non‐behavioural reasons are suggested to explain the mode of action of the oil.
