ER, excito-repellency; Esc, escaped mosquitoes; NEsc, non-escaped mosquitoes; KD, knockdown; LC, lethal concentration; DC, discrinimating concentration.

*Percent escape in control group showed no significantly difference (P > 0.05) between noncontact and contact tests at the same concentration.

**Percent escape adjusted with paired controls using Abbott’s formula. Different letter indicates significant differences (P < 0.05) between noncontact and contact tests in treatment group at the same concentration.

***Different letter indicates significant differences (P < 0.05) between control, noncontact and contact tests at the same concentration and same response group (Esc. or NEsc.).

^§Percent contact escape adjusted with paired noncontact escape response using modified Henderson-Tilton’s formula.

†Due to TFT vaporization during drying period, the actual percent concentration at the time of testing is less than initial paper treatment percent indicated.

30-min KD and 24-hr mortality not observed in controls.
