Survival (l_x; left axis and curve) and fecundity (m_x; right axis and histogram) over time for unselected and selected strains. Survival analysis found no significant differences in longevity due to selection with insecticide or strain (see Supplemental Table S3 for full descriptive statistics from survival analysis). Adult survival reached 50% at 31.1 (±0.94), 31.6 (±2.60) and 34.0 (±3.30) weeks for the unselected LA1, CIN1 and NY1 strains, respectively and at 32.5 (±1.58), 30.6 (±2.34) and 28.6 (±2.77) weeks for the paired selected strains. The average time from the egg to adult molt was 10.8 (±0.63), 10.0 (±0.70), 10.3 (±0.25) weeks for the unselected LA1, CIN1 and NY1 strains, respectively and 10.5 (±0.87), 9.3 (±0.63), 10.3 (±0.85) weeks for the paired selected strains. The average number of eggs laid during an individual female’s lifetime was 165.8 (±17.7), 154.0 (±24.9), 126.8 (±11.6) for the unselected LA1, CIN1 and NY1 strains, respectively and 134.2 (±11.5), 84.9 (±9.7), 65.7 (±13.9) for the paired selected strains.
