  1. 1 Cohort exposed from 0600–1200 hours and released immediately afterwards.
  2. 2 Cohort exposed from 1200–1800 hours but released only after a holding period of 12 h.
  3. 3 3–5 day old starved females.
  4. 4 Different lowercase letters in the same column indicate significant differences between mean recapture percentages for released females within release trial types (IR or DR; Kruskal-Wallis 95% confidence limit ) or between IR and DR trials (Mann-U Whitney Test, 95% confidence limit).
  5. 5 Different lowercase letters in the same column indicate significant differences between mean recapture percentages for released females between IR and DR trials (Mann-U Whitney Test, 95% confidence limit).
  6. 6Total recaptured /total released minus total knock down.
