Modelling the effect of multi-year aphid infestation on fruit production in perennial trees
Aphids are commonly considered major agricultural pests because of their ability to alter host plant physiology and impair foliar growth.
However, their effect on fruit production in perennial trees did not receive wide attention and few existing works have mainly focused on plant-aphid dynamics in a single growing season (i.e., few months). We modified an existing process based model for the peach tree Prunus persica - aphid Myzus persicae pathosystem, explicitly considering interactions between the two species under the influence of cultural practices (i.e., winter pruning and nitrogen fertilization), in order to consider multi-year dynamics.
The new multi-year model suggests that consequences of aphid infestation, in terms of fruit production, become evident only when considering multi-year dynamics.
