Burchellin individual treatment on A. aegypti at 0.5 - 30 μg/mL concentration. Values are mean ± standard deviation (X ± SD), average of three replicates of 10 larvae L3 per each group. Values followed by the same letter did not significantly different from each other, P > 0.05 when the Tukey test was used. Significance levels are represented as ***P < 0.001 vs. Control 2 = Acetone control.
