Why aphid virus retention needs more attention: Modelling aphid behaviour and virus manipulation in non-persistent plant virus transmission
Fig 4
MIP-BAR model is more similar to the BAR than the MIP model.
(a) Epidemic trajectories for MIP, BAR and MIP-BAR models using the default parameterisation (Table 2). Note it is difficult to distinguish the BAR and MIP-BAR models for this parameterisation and for the default initial condition. (b) Comparison of BAR trajectory to MIP-BAR trajectories at the default parameterisation, varying Z(0) (the initial number of infective aphids) in the MIP-BAR model. The inset shows behaviour for small values of t (up to 1 day). (c) I-Z phase plane for MIP-BAR model, showing I cline (dI/dt = 0 in Eq 24; blue) and Z cline (dZ/dt = 0 in Eq 25; green), and epidemic trajectories from (b). The inset shows a zoomed in section of the graph for small values of Z/A and I/H, to make it clearer where the model trajectories hit the Z cline.
