Stability plots, under the assumption of no host self-regulation.

<p>Regions shaded light grey correspond to a stable equilibrium, dark grey regions correspond to 2-point limit cycles, and regions shaded black correspond to higher-period cycles or chaotic dynamics; (A) β<i>_f</i> = β<i>_m</i> = 2.5; (B) β<i>_f</i> = 1.25 and β<i>_m</i> = 3.75. Other parameters are: α = 0.495, γ<i>₁</i> = 0, γ₂ = 0.005 and δ = 1.
