Figure 2
Susceptibility of G. platensis adults after exposure to several strains of M. anisopliae and B. bassiana applied with a single concentration of 1 × 108 conidia mL−1. (A) Speed to kill represented by 50% and 90% lethal times (LT50/LT90, in days) estimated with Weibull models fitted to survival censored data of several fungal strains. Lethal times are significantly different when their 95% confidence intervals (whiskers) do not overlap. (B) Hazard ratios (square symbols) for fungal infection compared to the commercial mycoinsecticide Boveril, which is assigned as the reference group and currently registered to control Gonipterus spp. in Brazil. Significant P-values are indicated by asterisks (*< 0.05, **< 0.01 or ***< 0.001) and represent the strains that were significantly different (more/less virulent) from the reference Boveril. Whiskers represent the 95% CIs.
