*F0 and F1 whitefly adults are those that we fed with a rifampicin diet solution and their offspring respectively; RF: rifampicin-treated whitefly, U: untreated whitefly; Data are means of 8 replicates with standard errors ( ± SE); the different letters in the same column within each whitefly generation indicate significant differences based on LSD test after one-way ANOVA (P < 0.05); “—”: no data because none of the F2 eggs hatched.
