Table 2. Xylella fastidiosa frequency of detection (%) in saliva samples from H. vitripennis that fed on grapevines or citrus. Table shows frequency of detection calculated independent of titer group and when the data set was partitioned in two groups containing below or above 5000 copies/μl of sharpshooter head.
| Host plant | Frequency of detection (%) | ||
|---|---|---|---|
| Independent of titer group | Titers below 5000 | Titers above 5000 | |
| grapevines | 26 (SE ±0.089; n =20) | 25 (SE ±0.10; n =8) | 26 (SE ±0.13; n = 12) |
| citrus | 36 (SE ±0.085; n = 30) | 41 (SE ±0.13; n = 19) | 26 (SE ±0.078; n = 11) |
