Notes.
a
Log-rank tests were applied to Kaplan–Meier survival curves to compare differences in escape patterns (time-to-escape) over the ER assay period.
b
Mann–Whitney U tests were used to compare final escape proportions at the end of the ER assay between concentrations.
*
Significant difference P < 0.05.
% w/v means percent of weight (g) of repellent in the total volume of solution.
LC50 of deltamethrin, permethrin, and alpha-cypermethrin are 0.00035%, 0.01030%, and 0.00046%, respectively.
