Understanding how climate, natural and agricultural landscapes challenge pathogens, vectors, and their natural enemies and shape their dynamics is the key to managing this pathosystem. This chapter provides an overview of this complex system and its evolution. The chapter includes a case study of biological control of aphids causing wheat BYDV in Brazil. The current challenge is to create tools that integrate knowledge of this complex pathosystem and facilitate monitoring and decision making for rational management to reduce the burden of disease.  aBarley yellow dwarf virus  aGrasses  aPathogens1 aMAR, T.
