Figure 1.

Effect of antibiotics and Enterobacter sp. NAB3 on susceptibility of six Lepidoptera species to Bacillus thuringiensis. Mortality for larvae of each species was analyzed by ANOVA. Each bar represents the mean mortality ± SEM of 36 larvae (three replications with 12 larvae each). Means were separated for significance according to Fisher's protected LSD at P < 0.05 (Vc: F = 189.11, df = 4, P < 0.0001; Ms: F = 47.32, df = 4, P < 0.0001; Pr: F = 280.37, df = 4, P < 0.0001; Hv: F = 93.07, df = 4, P < 0.0001; Pg: F = 36.21, df = 4, P < 0.0001; Ld: F = 47.32, df = 4, P < 0.0001).
