Burchellin treatment on A. aegypti at 0.001 – 0.5 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 and *P < 0.05 vs. Control 2 = Acetone control. NO = not observed.
