These last years were marked by increased problems of flavescence dorée in vineyards leading to an increased activity of our research group on it, and the emergence of new models, as well as the arrival of Lobesia botrana in the United States and of Drosophila suzukii in Europe. I hope we will contain any invasion of pierce disease in Europe in the vineyards. I wish we would see one day efficient biological agents against pathogens, and soon the development of molecular tools for early diagnostics in the vineyards and in reservoir host. It is noteworthy that new organisation of the meetings with a plenary session dedicated to IPM allowed to exchange more between entomologist and pathologist and I hope it was in favour to the transfer of the knowledge and methods into practice. We had the pleasure during these last meetings to see more countries participating, especially people outside from the WPRS area, which highlights how the European viticulture and vine protection is attractive and our group is active. I sincerely thank my colleagues who helped me during these years for managing the different sub-groups: Cesare Gessler, Hans Kassemeyer, Andrea Lucchi, Michael Meixner, Denis Thiery, Tirtza Zahavi, Carlo Duso, and Christoph Hoffmann. I greatly appreciate their help and experience in animating the meetings, in sharing their knowledge, in reviewing the papers, but also their friendship which makes our IOBC meetings so friendly. I also would like to thank our two liaison officers Sylvia Blümel and Mauro Jermini who were or are the warrantors of the IOBC institution. But of course, the group is there because people dedicate a lot of their time to organise the meetings. Then I would like to give a particular thank to Hans, Denis, Cesare, Gudrun and all their staff, for organising the meetings, taking the financial risk, to make them so that we only keep in memory the beautiful adventures of sharing knowledge and good wines and of encounters with local people involved into viticulture and passionate by it. This bulletin is the shortest we had since these last seven years (Figure 1) and it highlights that because the stakes of science are increasingly competitive it became more complicated to publish in grey literature. Maybe more systematic publications or special issues in the Biocontrol journal or others could help to perpetuate the production of our IOBC-WPRS group. The reduction of pesticides and Biological control, which is the heart of IOBC-WPRS, is becoming more and more evident in the European legislation, especially for viticulture. But it will probably be necessary for our group to open up to new themes such as plant-pathogen interactions, varietal resistance, biodiversity, ecology, precision viticulture, diagnostic tools and participatory science. Our winegrowers are always more innovative to make new wines, let us be the same for an agroecological viticulture.
