abstract: Many pathogens of plants are transmitted by arthropod
vectors whose movement between individual hosts is influenced by
foraging behavior. Insect foraging has been shown to depend on both
the quality of hosts and the distances between hosts. Given the spatial
distribution of host plants and individual variation in quality, vector
foraging patterns may therefore produce predictable variation in ex-
