Description of experiments and the treatments tested with female Aedes aegypti mosquitoes.

Twenty mosquitoes were tested with a treatment (0 hr) and then re-tested after 3 hours. Experiment 1 tested against a control arm (0.5 ml ethanol) (CA) or DEET on an arm (0.5 ml, 20%) (DA). N = 10. Individuals collected for EAG were sensitive (s) or insensitive (i) to DEET, or collected at random. Experiment 2 tested a nylon control on a heat source (0.5 ml redistilled hexane) (H), or DEET on a section of nylon on a heat source (0.5 ml, 20% in redistilled hexane) (HD). N = 10. Experiment 3 tested DEET on a section of nylon tights with no arm present (0.5 ml, 20% DEET) (D). N = 10.
