Modelling the spread and mitigation of an emerging vector-borne pathogen: Citrus greening in the U.S.
Fig 5
The role of primary and secondary transmission rates and forces of infection on HLB Spread in the Lower Rio Grande Valley, Texas HLB spread.
(A) Posterior distribution of transmission rates via four sources: movement of local vectors from infectious trees in the landscape (β), the arrival of infected vectors over the international border (εB) and from further away (εw)and introduction of infected trees by other human-mediated movement (ε). (B) Contribution of the human-mediated, psyllid-driven primary infection and psyllid-driven secondary transmission sources to the realised infection pressure overall on susceptible trees in the survey period 2012–2018.
