The effects of R. isatidis extract on extending the lifespan of CSBV-infected larvae. a The daily survival rate of different groups. b The overall survivor rate during a period of observation of different groups. In Group-I (CK), larvae received neither CSBV no R. isatidis extract. In Group-II, larvae were inoculated with CSBV without treatment of R. isatidis extract. In Group III, larvae were inoculated with CSBV and treated with R. isatidis extract. The different lower case letters above bars indicate the statistically significant difference among different groups (P ≤ 0.05, ANOVA and Tukey´s tests)
