This work was conducted to determine: 1) the kinetics of Candidatus Liberibacter asiaticus (CLas), presumed causal agent of huanglongbing disease, transmission by Asian citrus psyllids and 2) if differences in incidence of CLas infection and titer differed among 16 citrus genotypes.  Results have implications for studies to screen cultivars for their propensity to succumb to HLB.
