Potato virus Y (PVY) is responsible for major viral diseases in most potato seed areas. It is transmitted by aphids in a non-persistent manner, and it is spread in potato fields by the winged aphids flying from an infected source plant to a healthy one. Six different PVY strains groups affect potato crops: PVY C , PVY N , PVY O , PVY N:O , PVY NTN , and PVY N-Wi . Nowadays, PVY NTN and PVY N-Wi are the predominant strains in Europe and the USA. After the infection of the leaf and accumulation of the virus, the virus is translocated to the progeny tubers. It is known that PVY N is better translocated than PVY O , but little is known about the translocation of the other PVY strains. The translocation of PVY occurs faster in young plants than in old plants; this mature plant resistance is generally explained by a restriction of the cell-to-cell movement of the virus in the leaves. The mother tuber may play an important role in explaining mature plant resistance. PVY is able to pass from one stem to the other stems of the same plant through the vascular system of the mother tuber, but it is unknown whether this vascular link between stems is permanent during the whole life of the plant. Two greenhouse trials were set up to study the spread of PVY in the vascular system of the potato plant. The PVY-susceptible cultivar Charlotte was used for both trials. It was demonstrated that all stems growing from a PVY-infected tuber will become infected sooner or later, and that PVY N-Wi translocates more efficiently to progeny tubers than PVY NTN . It was also demonstrated that the progressive decay of the mother tuber in the soil reduces the possibility for virus particles to infect healthy stems through the vascular system of the mother tuber. This new element contributes to a better understanding of the mechanism of mature plant resistance.

“…Work in this area has continued. For example, recently Boquel et al (2013) found that mineral oil was effective at inhibiting the acquisition of PVY by Rhopalosiphum padi from infected potato plants. However, it is unknown whether this method would be affordable or costeffective for small-scale farmers.…”

“…Mineral oil has been proven to efficiently reduce the spread of various non-persistent viruses such as Cucumber mosaic virus (Loebenstein et al, 1964), Turnip mosaic virus (Lowery et al, 1990), Tulip breaking virus (Asjes, 1984), and Potato virus Y (PVY) (Potyviridae: Potyvirus) (Bradley et al, 1966;Fageria et al, 2014a,b). Mineral oil is believed to act as an insecticide (Mart ın-L opez et al, 2006;Najar-Rodr ıguez et al, 2007a,b), to impede infection processes by preventing the development or translocation of the virus in the plant (Loebenstein et al, 1964;Peters & Lebbink, 1973), or to physically interfere with virus retention at the tip of the aphid's stylets (Wang & Pirone, 1996;Boquel et al, 2013).

Aphids that colonize and reproduce on potato are some of the most efficient vectors of Potato virus Y (PVY) (Potyviridae: Potyvirus), and hence these aphids have been the focus of the majority of studies to date. However, other non-colonizing aphids can also function as vectors. Mineral oil is the only product available to growers that effectively prevents the spread of PVY in potato seed production. Most previous studies focused on the effect of mineral oil on the behavior of aphids on their preferential host plant, and consequently there is a lack of information for non-colonizing aphids on potato plants. The objective of this study was to determine the effect of spraying potatoes with one of two mineral oils, Superior 70 or Vazyl-Y, on host selection and probing behavior of the non-colonizing aphid Rhopalosiphum padi (L.) (Hemiptera: Aphididae). The electrical penetration graph (EPG) technique, combined with ethological observations, determined that there was no difference in R. padi behavior on potato plants treated with Superior 70. However, there were few significant changes in R. padi behavior on plants sprayed with Vazyl-Y, including a delay in the initiation of stylet penetration and an increase in the duration of xylem sap ingestion. These new data support previous results and confirm that the mode of action of mineral oil in the reduction of the spread of PVY is not solely due to the modification of the behavior of aphids.
