Fig 3. Results from the transmission model showing within-season dynamics.
Within-season dynamics in (a) infection prevalence and (b) adult population size within the milkweed patch for a range of pathogen persistence times (in days, 1/μw). Longer pathogen persistence produced higher infection prevalence and slightly lower adult population size. The dynamics shown assume an intermediate value for parasite shedding rate (λ = 150 leaves/day/adult); all other parameter values are listed in Table 1.
