Multi-directional interactions occur among plant hosts, Brevipalpus mites and the plant viruses they transmit. Such interactions should be considered when evaluating the severity of a disease such as citrus leprosis. The current understanding of Brevipalpus-transmitted viruses relies on the capability of the vector to transmit the disease, the persistence of the virus in the host plant and the ability of the disease to spread. Previously, we discussed the Citrus leprosis virus (CiLV) and its importance and spread over the past decade into new areas of South and Central America, most recently into southern Mexico and Belize. Here, we address key questions to better understand the biology of the mite vector, fitness costs, and the peculiarities of Brevipalpus mite reproduction, virus survival, transmissibility and spread, and the expansion of the host plant range of Brevipalpus species vectoring the disease.
植物宿主、短须螨和它们传播的植物病毒之间存在多向相互作用。在评估诸如柑橘溃疡病等疾病的严重程度时，应考虑这些相互作用。目前对短须螨传播的病毒的了解依赖于载体传播疾病的能力、病毒在宿主植物中的持久性以及疾病传播的能力。此前，我们讨论了柑橘溃疡病病毒（CiLV）及其在过去十年中传播到南、中美洲新地区的重要性，最近传播到了墨西哥南部和伯利兹。在这里，我们将解决一些关键问题，以更好地了解螨类传播媒介的生物学特性、适应成本，以及短须螨繁殖、病毒存活、传染性和传播以及携带疾病的短须螨宿主范围扩大的特殊性。
