Mosquito species	Conc (ng/ml)	Total no. surviving females	Oviposition rate of survivors (%)	Geometric mean no. of eggs laid per ovipositing female (95% CI)	Overall hatch rate (%)	Theoretical number of larvae produced per 1000 surviving females

Anopheles stephensi mosquitoes were blood fed one time on either treated or untreated blood. Anopheles albimanus mosquitoes were blood fed twice; once on untreated blood and again, 2 days later, on either treated or untreated blood. Engorged mosquitoes were held individually in oviposition vials. Superscripts indicate statistically significant differences for parameters within a species
