Fig. 1.

Percent mortality of 2nd instar nymphs of mealybug Drosicha mangiferae exposed to methanolic extracts of different plants. Columns represent average percent mortality of mealybug individuals ± standard error (n=5). For each botanical extract, small alphabets indicate statistical difference among the concentrations (two-way ANOVA; LSD at α = 0.05), while capital alphabets indicate statistical difference among botanical extracts (factorial ANOVA; LSD at α = 0.05).

Fig. 2.

Percent mortality of 2nd instar nymphs of mealybug Drosicha mangiferae exposed to different plant essential oils. Columns represent average percent mortality of mealybug individuals ± standard error (n=5). For each essential oil, small alphabets indicate statistical difference among the concentrations (two-way ANOVA; LSD at α = 0.05), while capital alphabets indicate statistical difference among essential oils (factorial ANOVA; LSD at α = 0.05).
