Also in plant pathology and especially in plant virology [4], this detection system has been applied frequently, enabling studies which were difficult or impossible before the gold era.

About 76% of the insect vectors of plant viruses belong to the order Homoptera [15], mainly aphids (Aphididae), leafhoppers (Cicadellidae), plant-hoppers (Delphacidae), whiteflies (Aleyrodidiae), and mealybugs (Pseudococcidae). These insects have piercing and sucking mouthparts

After an initial biotrophic phase of varying duration, these fungi switch to necrotrophy. Such
