Figures & Tables

Figure 1:

Mean percentage mortality (95% confidence level) of Tuta absoluta larvae inoculated with 0, 10, 20, and 40 IJs/insect of Steinernema yirgalemense and Steinernema jeffreyense (two-way ANOVA: F (3, 28) = 17.50, p < 0.001) in a laboratory trial. Different letters above the vertical bars indicate significant differences (p < 0.05).
