Relative amount of TYLCV in tomato leaves as affected by type (H⁺ vs. H⁻ Q) and sex of B. tabaci. H⁺ F: H⁺ females; H⁻ F: H⁻ females; H⁺ M: H⁺ males; H⁻ M: H⁻ males.

The abundance of the TYLCV gene (normalized to the abundance of the Tomato 25S ribosomal RNA gene) was assessed by q-PCR 10 days after tomato plants had been exposed to a single whitefly for 24 h. Each combination of whitefly type and sex was represented by five replicate plants. Vertical lines on each bar represent standard deviations of the mean. Different letters indicate significant differences between the four treatments (P < 0.05).
