A summary of the article is shown below:
Reports of spatial patterns of Candidatus Liberibacter asiaticus (Las)-infected asymptomatic citrus trees and Las-positive Asian Citrus Psyllids (ACP) are rare, as are published relationships between huanglongbing (HLB), ACP and weather. Here, spatial patterns of Las-positive asymptomatic and symptomatic trees were determined every half year in a small grove over 2.5 years, and of HLB-symptomatic trees and (Las-positive) ACP populations every month in two commercial groves for one year. Spread of symptomatic trees followed that of asymptomatic Las-positive trees with <6 months delay. Las-positive (a)symptomatic fronts moved at 2.5-3.6 m month-1. No spatial relationship was detected between ACP populations and HLB infected trees. HLB incidence and Las-positive ACP dynamics were tentatively positively correlated with monthly rainfall data and to a lesser extent with average minimum temperature.
