Ecology of Aphidophaga

International symposia on the research into behaviour and ecology of aphidophagous insects

This series of symposia has traditionally been seen as a unique scientific forum for discussions on ecological and behavioural interactions within this guild.  Its focus is to understand how the spontaneous “natural control” works, with the aim to improve it.  After an initial couple of  meetings in the Czech Republic, symposia were organised in Poland, Hungary, France, Belgium, Canada/Quebec, Portugal/Azores, Czech Republic, Greece, Italy, Serbia, Germany, Canada, Spain/Catalonia.
