Abstract

Huanglongbing (HLB), spread by a psyllid vector, is globally considered a major threat to commercial and sustainable citrus production. Better understanding of the vector-mediated patterns of HLB spread is essential to inform and maximize disease management. From previous studies, edge effects are a significant characteristic of the HLB pathosystem and have been observed predominately in larger plantings. In this study, we investigated 1) the impact of different edge classes and orientations, 2) the quantitative influence of distance from edges, and 3) the temporal dynamics of each edge effect. Spatial analyses of edge effects were conducted on two years of HLB incidence data from the Southern Gardens plantation in south Florida.
