of mosquito activity? To investigate this question, we shifted the MOSQUITO
BREEDING SEASON graph to begin one month earlier (Line 2 in Figures 12.15
and 12.16) or to begin one month later (Line 3 in Figures 12.15 and 12.16). Line
1 in these figures is the base seasonal onset of activity (from approximately April
to September) as was used in the previous section. What we see is that an earlier
onset of mosquito activity results in a longer period during which to amplify the
disease through the host-vector feedback loop. This affects the host as a higher cu-
mulative exposure (peak SEROPREVALENCE) for birds which occurs earlier in
