Fig 3. Contact toxicity of methyl benzoate against adults of Bemisia tabaci.

For direct spray application on whitefly infested tomato leaves (A), various concentrations of MB solution (~0.5 mL total) were sprayed on < 5-d-old adults of B. tabaci (n = 20). For residual toxicity (B), various concentrations of MB solution (~0.5 mL total) were first sprayed on tomato leaves and allowed to dry for 2 h before < 5-d-old adults (n = 20) were released into an insect breeding cup containing the leaves. Values are the means of three replicates.
