Why aphid virus retention needs more attention: Modelling aphid behaviour and virus manipulation in non-persistent plant virus transmission
Fig 5
The MIP and MIP-BAR model predictions vary differently across parameter values, driven by variability of behaviour-based aphid rates and
in the MIP-BAR model.
Each column has the same plot for: ω (aphid feeding probability; top row), a (aphid virus acquisition rate; middle row) and Γ (plant death/replanting rate; bottom row) parameters, respectively. Left (a)/(d)/(g): parameter versus MIP-BAR/MIP model aphid infectivity loss rate (rate at equilibrium for MIP-BAR model, calculated as in Eq 20); Middle (b)/(e)/(h): parameter versus MIP-BAR/MIP model aphid dispersal rate (rate at equilibrium for MIP-BAR model, calculated as in Eq 14); Right (c)/(f)/(i): parameter versus disease incidence (equilibrium I/H) for MIP, MIP-BAR and BAR models. For all plots, the red point signifies the default parameterisation. Apart from the parameter being altered in each graph, all parameters are at their default values in all plots (Table 2). Note that in all cases the disease incidence for the BAR model and the MIP-BAR model are identical; note further that the parameters and
are not defined for the BAR model.
