Effects of varying intervention strategies on the magnitude of \({\mathcal{R}}_{0}\). Here we set \(u=u_{E},u_{L}=u_{P}=u_{A}\). (a) Dynamics of \({\mathcal{R}}_{0}\) on a wide ranges of values for u. (b) Zoomed graph, that is, an illustration of the dynamics of \({\mathcal{R}}_{0}\) for a refined range of values for u. From the results we can note that any value of \(u>0.5\) leads to the extinction of the pest, and persistence of the pests occurs for \(u<0.5\)
