Wie wirkt sich die Variabilität der Wirtspflanzen auf die Schädlinge aus?

Crop plants are affected by a variety of pests that negatively impact quality and yield. Chemical pesticides have affected these pests, which are resistant and difficult to control. The demand for biological pest control has increased. Farmers purchase predatory mites and release them onto the crops, but the predatory mites often disperse or do not reproduce, necessitating frequent releases that can be costly. Therefore, methods to promote the establishment and reproduction of predatory mite populations are needed to combat pests over a longer period. One effective method is the use of biological pest control plants, such as banker plants.
