The above evolved during a field trip in 2011. Man-Miao Yang, Gene-Sheng Tung, and colleagues took the Japanese colleague Makoto Tokuda to collect galls along a remote trail in southern Taiwan and, on the way back, found a car covered in dust. Man-Miao naughtily wrote LET’S GALL on the rear window of that dusty car. We derived that phrase into our slogan Let’s Gall Taiwan for the 7th gall symposium. We hope that the slogan will be adopted by future symposium organizers, replacing the country name. Although the previous symposia of this series were known as ‘gall symposia’ in short, specific titles given to each of them varied. For the first time, we introduce the word ‘Cecidology’ into the title of the symposium to be held in Taiwan. We hope this change will attract more people to participate, since the historical popularity of the term cecidology. The formal title has, thus, become ‘The 7th International Symposium of Cecidology’ subtitled ‘Ecology and evolution of gall-inducing arthropods’.

Huisun Experimental Forest Station, Taiwan
The Experimental Forest Station has been established since 1949 by National Chung Hsing University. It covers a diverse environment, located over sea level 500m average altitude and up to 2400m. The average temperature of Huisun Experimental Forest Station is 16 – 20°C in March.
History of the Symposium
The concept of an international gall-inducing arthropod symposium was developed by William Mattson (Pennsylvania, USA) and Yuri Baranchinkov (Siberia, Russia) in 1992. The meeting was organized under the guidelines of the International Union of Forestry Research Organizations (IUFRO). The first symposium was held at the Sukachev Institute of Forest and Wood, Siberian Branch of the Russian Academy of Sciences, with support from the International Union of Forest Research Organizations (IUFRO) at Krasnoyarsk, Siberia, with Yuri Baranchikov and Peter Price as organizers, between the 9th and 13th of August of 1993. The proceedings of the symposium were published as The Ecology and Evolution of Gall-Forming Insects edited by Peter Price, William Mattson, and Yuri Baranchikov (1994) by the United States Department of Agriculture’s Forest Service, North Central Forest Experiment Station General Technical Report NC‒174. This publication includes 22 papers written by 45 contributors. Treated themes include ecology and population dynamics, effects of the physical environment on gall-inducing arthropods, biodiversity and distribution, genetic variation in host-plant resistance, and evolutionary perspectives. These themes have prevailed in subsequent meetings. Price and a few other participants at this symposium took the Trans-Siberian train, and their travel has left unforgettable experiences and indelible stories.
The success of the first symposium prompted future symposia in different nations. The second symposium was held in Mátrafüred, Hungary, organized by György Csóka of the Hungarian Forest Research Institute, from the 14th to the 19th of August of 1997. The meeting included 32 oral presentations and 12 posters. Participants were from around the world representing 20 countries: Australia, Belgium, Brazil, Canada, Czech Republic, England, Finland, France, Germany, Hungary, Israel, Poland, Republic of China, Russia, Scotland, South Africa, Spain, Sweden, Taiwan and the USA. The proceedings of the symposium were published as The Biology of Gall-Inducing Arthropods, edited by György Csóka, William Mattson, Graham Stone, and Peter Price (1998), as North Central Research Station General Technical Report NC-199 from the United States Department of Agriculture Forest Service.
The third symposium was held in Stellenbosch, South Africa, from the 15th to the 18th of January of 2002. The meeting was organized by Schalk Louw, Jeanne Stoltz, and Jan Giliomee, which attracted 49 participants. A field trip to a conservation area of Fynbos vegetation near Hermanus on the south coast, east of Cape Town occurred. No publication resulted from this meeting.
The fourth symposium was held in Kyoto, Japan from the 5th to the 9th of September of 2005. The organizers were Junichi Yukawa, Takayuki Ohgushi, and Kenichi Ozaki. The proceeedings were published as a book, the Galling Arthropods and their Associates: Ecology and Evolution edited by Kenichi Ozaki, Junichi Yukawa, Takayuki Ohgushi, and Peter Price (2006) published by Springer-Verlag, Tokyo. This publication includes 26 papers written by 75 authors.
The 5th symposium was held in Serro do Cipó in Brazil from the 9th to the 14th of August of 2009. The organizers were Wilson Fernandes, Peter Price, and Heikki Roininen. Thirty oral presentations were made at this symposium. A field trip into the cerrado vegetation of Serro do Cipó provided a great opportunity to this area with exceptionally high diversity of gall-inducing arthropods. At this stage, no proceedings are available from this symposium.
The 6th symposium was held in O’Reilly’s Rainforest Retreat, Queensland, Australia, from the 4th to the 8th of August 2013. The organizers were Robin Adair, Gary Taylor, Anneke Veenstra, and Peter Kolesik. There were 10 sessions with about 50 oral presentations plus 22 posters. A workshop on the gall midges of mango tree was held during this symposium. At this stage, no proceedings are available from this symposium.
The gall symposium has been working closely with the IUFRO Working Party 7.03.02 – Gall-forming insects.
