Vector-borne plant pathogens frequently alter host-plant quality and associated plant cues in ways that influence vector recruitment and pathogen acquisition. Furthermore, following acquisition by the vector, pathogens may influence subsequent vector behavior either directly or via effects on the host plant. Given that such effects have significant implications for pathogen acquisition and inoculation, selection might be expected to favor patterns of pathogen effects on host-vector interactions that are conducive to transmission. Consequently, we might also expect to observe broad similarity in the effects of pathogens sharing similar modes of transmission. Here we discuss some specific hypotheses arising from these expectations and the implications of recent empirical findings. On the whole, this evidence is consistent with the expectation that pathogen effects on host-vector interactions are often (though not always) adaptive with respect to transmission.
虫媒传播的植物病原体经常以影响媒介招募和病原体获取的方式改变宿主植物的质量和相关植物线索。此外，在媒介获得病原体后，病原体可能会直接或通过对宿主植物的影响来影响随后的媒介行为。鉴于这些影响对病原体获取和接种具有重大意义，选择可能有利于有利于病原体对宿主-媒介相互作用影响的模式，有利于传播。因此，我们也可能期望观察到具有相似传播模式的病原体的影响具有广泛的相似性。在这里，我们讨论了一些基于这些预期和最近的实证发现的具体假设。总的来说，这一证据与以下预期一致，即病原体对宿主-媒介相互作用的影响通常（尽管并非总是）与传播有关。
