“…Reviews and research papers by the late J.M. Thresh [ 32 ] described plant virus disease pandemics or major epidemics that occurred across the world between the early 1900s and 2006, e.g., [ 4 , 6 , 12 , 13 , 14 , 18 , 22 , 33 , 34 , 35 , 36 , 37 ]. His comprehensive global review published in 1980 described the origins and epidemiology of important plant virus diseases up until then [ 4 ].…”

The world’s staple food crops, and other food crops that optimize human nutrition, suffer from global virus disease pandemics and epidemics that greatly diminish their yields and/or produce quality. This situation is becoming increasingly serious because of the human population’s growing food requirements and increasing difficulties in managing virus diseases effectively arising from global warming. This review provides historical and recent information about virus disease pandemics and major epidemics that originated within different world regions, spread to other continents, and now have very wide distributions. Because they threaten food security, all are cause for considerable concern for humanity. The pandemic disease examples described are six (maize lethal necrosis, rice tungro, sweet potato virus, banana bunchy top, citrus tristeza, plum pox). The major epidemic disease examples described are seven (wheat yellow dwarf, wheat streak mosaic, potato tuber necrotic ringspot, faba bean necrotic yellows, pepino mosaic, tomato brown rugose fruit, and cucumber green mottle mosaic). Most examples involve long-distance virus dispersal, albeit inadvertent, by international trade in seed or planting material. With every example, the factors responsible for its development, geographical distribution and global importance are explained. Finally, an overall explanation is given of how to manage global virus disease pandemics and epidemics effectively.

“…Viruses constitute a major cause of plant disease and have an estimated economic impact of >$30 billion annually (11). They constitute almost 50% of pathogens responsible for emerging and reemerging plant diseases worldwide, and they damage natural vegetation as well as cultivated plants (12)(13)(14)(15)(16)(17).…”

Global Dimensions of Plant Virus Diseases: Current Status and Future Perspectives

Viral diseases provide a major challenge to twenty-first century agriculture worldwide. Climate change and human population pressures are driving rapid alterations in agricultural practices and cropping systems that favor destructive viral disease outbreaks. Such outbreaks are strikingly apparent in subsistence agriculture in food-insecure regions. Agricultural globalization and international trade are spreading viruses and their vectors to new geographical regions with unexpected consequences for food production and natural ecosystems. Due to the varying epidemiological characteristics of diverent viral pathosystems, there is no one-size-fits-all approach toward mitigating negative viral disease impacts on diverse agroecological production systems. Advances in scientific understanding of virus pathosystems, rapid technological innovation, innovative communication strategies, and global scientific networks provide opportunities to build epidemiologic intelligence of virus threats to crop production and global food security. A paradigm shift toward deploying integrated, smart, and eco-friendly strategies is required to advance virus disease management in diverse agricultural cropping systems.

“…Many general reviews, books and book chapters have been published on different aspects of the subject of plant virus ecology and epidemiology over the years (e.g. Matthews, ; Thresh, 1974 a , b , 1976, 1980 a , b , 1981 a , b , 1982, 1983 a , b , c , 1986, 1991, 2004, 2006 a , b , c , d ; Bos, ; Harrison, ; Gibbs, ; Tomlinson, ; McLean et al ., 1986; Robert, ; Hull, , ; Raybold et al ., 2003; Cooper & Jones, ; Power, ; Jones, , ; Malmstrom et al ., ; Roossinck, ; Wilson, ). To commemorate the Centenary of the Annals of Applied Biology and provide a historical perspective on the subject, this review (a) summarises the contributions of influential review articles in the journal covering the period since the beginnings of plant virology as a discipline until the present, and (b) provides examples from original research papers in the journal that illustrate important ecological and epidemiological concepts and new developments.…”

After clarifying the relationship between the closely related concepts of ecology and epidemiology as they are used in plant virology, this article provides a historical perspective on the subject before discussing recent progress and future prospects. Ecology focuses on virus populations interacting with host populations within a variable environment, while epidemiology focuses on the complex association between virus and host plant, and factors that influence spread. The evolution and growth of plant virus ecology and epidemiology since its inception to the present day, and the major milestones in its development, are illustrated by examples from influential historical reviews published in the Annals of Applied Biology over the last 100 years. Original research papers published in the journal are used to illustrate important ecological and epidemiological principles and new developments in both fields. Both areas are multifaceted with many factors influencing host plants, and virus and vector behaviour. The highly diverse scenarios that arise from this process influence the virus population and the spatiotemporal dynamics of virus distribution and spread. The review then describes exciting progress in research in the areas of molecular epidemiology and ecology, and understanding virus-vector interactions. Application of new molecular techniques has greatly accelerated the rate of progress in understanding virus populations and the way changes in these populations influence epidemics. Viruses cause direct and plant-mediated indirect effects on insect vectors by modifying their life cycles, fitness and behaviour, and one of the most fascinating recent fields of research concerns plant-mediated indirect virus manipulation of insect vector behaviour that encourages virus spread. Next, the review describes the current state of knowledge about spread of plant viruses at the critical agro-ecological interface between managed and natural vegetation. There is an urgent need to understand how viruses move in both directions between the two and be able to anticipate these kinds of events. To obtain an understanding of, and ability to foresee, such events will require a major research effort into the future. The review finishes by discussing the implications of climate change and rapid technological innovation for the types of research needed to avoid virus threats to future world food supplies and plant biodiversity. There has been lamentably little focus on research to determine the magnitude of the threat from diseases caused in diverse plant virus pathosystems under different climate change scenarios. Increasing technological innovation offers many opportunities to help ensure this situation is addressed, and provide plant virus ecology and epidemiology with a very exciting future.
