Table 1. Frequency of curing of primary symbiont Portiera and secondary symbiont Hamiltonella in F0* and F1* MED whitefly adults after the F0* adults were fed with a rifampicin diet-solution at various concentrations.
Rifampicin concentration (μg/ml) | N | No. of individuals with a given symbiont cured on day 0 |
No. of individuals with a given symbiont cured on day 13 |
No. of individuals with a given symbiont cured on day 30 |

*F0 and F1 whitefly adults are those that we fed with a rifampicin diet solution and their offspring respectively; N: the number of whitefly adults tested by diagnostic PCR analysis; the same letters in a columns indicate non-significant difference at α = 0.05 (Chi-square tests).
