The effect of major compounds of Cymbopogon flexuosus essential oil (citral and geranyl acetate) at a concentration of 18, 30, and 42 mg L−1 on the development of Aedes Aegypti larvae. The average larval length (LL), cephalic diameter (CD), and siphon length (SL) are presented in millimetres. (*) Significant differences in LL between concentrations of each substance and the control group (Tukey’s test, p ≤ 0.05). (A) Citral (analysis of variance [ANOVA]: F = 8.391, df = 2, p = 0.007476); (B) geranyl acetate (ANOVA: F = 8.391, df = 3, p = 0.0007476).
