Estimated number of wild female Ae. aegypti/premise based on three levels of daily survival in Babinda and Machans Beach. Wild female Ae. aegypti populations estimated from estimated number of released mosquitoes and relative increase change in BG-S collection as the recapture rate. Confidence intervals of the estimated female population were calculated by multiplying the estimated population by the CIs (as a proportion of the mean) for the BGS collection from 2 weeks before release
