Fig. 2. — (A–D) Proportions of healthy and latent flush (A), proportions of asymptomatic and symptomatic flush (B), populations of uninfected and infected nymphs per flush (C), and populations of uninfected and infected adult psyllids per flush (D). The latent flush is infected but not yet infectious. The asymptomatic and symptomatic flush are both infected and infectious. Infected adult psyllids are infectious and consist of categories A1 = and A2 = . Input rate of healthy flush follows a periodic function with two peaks in 1 y. The parameter for internal movement of the pathogen in the tree, .
