On behalf of 
the International Committee of Plant Virus Epidemiology (ICPVE), a subcommittee 
of the International Society of Plant Pathology (ISPP), and the Local Organizing 
Committee, with the support of the Brazilian Phytopathological Society (SBF), we 
have the pleasure to announce that  
The 16th International Symposium of Plant Virus Epidemiology 
(ISPVE) will be held in São Paulo, Brazil, from June 30th to July 
3rd, 2025. 
We invite scientists, 
professionals and students interested in plant virus epidemiology to attend 
the symposium, which will have the following theme: “Epidemiology 
and management of plant viruses and their vectors: a challenge for agriculture 
in the 21st century”, focusing on ecology, epidemiology, and 
pathogen-host-vector interactions. 
The four-day event will bring together specialists in the epidemiology of plant 
virus and other vector-transmitted plant pathogens and will provide an excellent 
opportunity to present and discuss scientific advances in this area. It will 
also be a chance to promote debate and reflection on the global social and 
economic consequences of plant virus epidemics and the challenges for the 21st 
century in solving problems intelligently, efficiently, and sustainably. The 
symposium will include oral and poster presentations. The activities will begin 
each day with the presentation of a topic by a prominent researcher in the area, 
followed by oral presentations, previously selected from all the abstracts 
submitted for that topic. On each day, there will be time allocated for personal 
discussions to encourage collaboration between the symposium participants. In 
addition, on the last day of the event, participants will have the opportunity 
to visit research institutions and cultivation areas to learn about research and 
agriculture in Brazil. 
The main topics addressed will include the results of recent research involving 
etiology, diagnostic methods, ecology, diversity and evolution of plant viruses 
and their vectors, virus-host-vector interactions, in addition to general 
aspects of epidemiology, epidemic disease surveillance models, and strategies 
for the management and control of virus-borne diseases. Research involving other 
phytopathogens transmitted by vectors, such as Xylella fastidiosa, 
Candidatus Liberibacter spp., Ca. Phytoplasma spp. and Spiroplasma 
spp., which have caused major epidemics in recent years, will also be addressed. 
In addition, discussions and reflections on epidemics will involve a careful 
look at climate change, sustainability, food security, and the quality of human 
life. We will be waiting for you in São Paulo, Brazil. So, save the date! 
The Organizing Committee 
thanks you for forwarding this first communication to your colleagues and 
societies. We look forward to welcoming you to São Paulo.
