评分

四项指标均为无量纲。总分是特异性、寄主距离与可信度的乘积。

0.500
特异性
1 / 媒介上的病原数量——在 EPPO 中该媒介传播 2 种病原。
1.00
寄主距离
1.0 = 无共享寄主 · 0.5 = 共享科 · 0.2 = 共享属 · 0.0 = 共享种。
0.25
可信度 (P-P)
K = 已确认媒介（1.0），P = 潜在（0.5）；两条边相乘。
0.125
总分
特异性 × 寄主距离 × 可信度

Xylella fastidiosa ↔ Lepyronia quadrangularis

* Sanderlin, R. S., and R. A. Melanson (2010) Insect transmission of Xylella fastidiosa to pecan. Plant Disease 94, 465-470. 
-------  Pecan bacterial leaf scorch. In experiments where Lepyronia quadrangularis specimens were caged on pecan trees, one out of six trees tested with two specimens became infected. The authors conclude that L. quadrangularis could be an occasional vector.
