1 Cohort exposed from 0600–1200 hours and released immediately afterwards.
2 Cohort exposed from 1200–1800 hours but released only after a holding period of 12 h.
3 3–5 day old starved females.
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).
