Field surveys in many cassava growing areas of Africa have assessed the incidence and severity of cassava mosaic disease (CMD), populations of the whitefly vector (Bemisia tabaci), and the distribution of cassava mosaic begomoviruses (CMBs). The methods employed differ greatly between countries and attempts at standardization were made in recent CMD surveys in East and Central Africa, notably in the systemwide Whitefly IPM Project, which provides a paradigm for future work on CMBs and whiteflies on cassava in Africa and also elsewhere. However, there is a need for greater standardization so as to assess the continued expansion of the current CMD pandemic in eastern Africa. Standardized methods will facilitate the collection of reliable data, which can be used to predict future disease spread, develop appropriate management strategies and compare disease development between seasons and locations. In this review, the methods used and the problems encountered during such surveys are discussed and recommendations made on future procedure.
在非洲许多木薯种植区开展的实地调查评估了木薯花叶病（CMD）的发病率和严重程度、粉虱传播媒介（烟粉虱）的种群数量以及木薯花叶双生病毒（CMB）的分布情况。各国采用的方法差异很大，近期在东非和中非开展的木薯花叶病调查尝试进行了标准化，特别是在全系统粉虱综合防治项目中，该项目为非洲及其他地区未来关于木薯上的木薯花叶双生病毒和粉虱的研究提供了范例。然而，需要进一步实现标准化，以便评估当前木薯花叶病在东非的大流行是否持续蔓延。标准化方法将有助于收集可靠数据，这些数据可用于预测未来疾病传播、制定适当的管理策略以及比较不同季节和地点的疾病发展情况。在本综述中，讨论了此类调查中使用的方法和遇到的问题，并对未来的程序提出了建议。
