Mineral oil interferes with potato virus Y in aphid stylets

Abstract Mineral oils have been used for many decades to control the transmission of plant viruses and their ensuing epidemics. Although it is not clearly defined, mode action these has extensively studied, effects on feeding behaviour orientation vector or virus by its often put forward as possible explanations. This study examines effect mineral oil interaction between potato Y (PVY) vector, green peach aphid Myzus persicae , with particular focus organ. A lipophilic staining technique was visualize inside insect's stylets first time. Virus binding localization were also examined in following PVY acquisition. The results indicate that presence leaves reduces likelihood acquiring virus. verified this reduced acquisition could be accompanied a reduction viral load, measured reverse transcription‐quantitative PCR stylets. retention measured. mechanism which impacts seems take place very early stages acquisition, well before attaches
