Susceptibility bioassay results with wild Anopheles gambiae sensu lato collected near the experimental hut site in Covè, southern Benin. Mortality was recorded after 24 h for pyrethroid exposures and after 72 h for chlorfenapyr. Pyriproxyfen susceptibility was assessed based on the reduction in fertility of surviving blood-fed mosquitoes relative to the untreated control observed via ovary dissection. Red dashed line represents the standard 98% susceptibility cut-off, while the grey dashed line represents the provisional 90% cut-off to confirm chlorfenapyr resistance. Error bars represent 95% confidence intervals
