Figure 1.
Egg-to-imago mortalities in the experimental populations (MCN-1, solid lines; MCN-2, broken lines) and their linear regressions on generation number t (0.1506 + 0.0012t in MCN-1 and 0.1829 + 0.0021t in MCN-2). The data for generation 15 are absent because back-up vials were used. The infecundity rate was ≈1% in MCN-1 and ≈2% in MCN-2.
