Local and landscape parameters explaining distribution and abundance of Episyrphus balteatus (De Geer, 1776) (Diptera, Syrphidae) in forests and edges of rural landscape

This series of symposia has traditionally been a unique scientific forum for discussions on ecological and behavioral interactions within the guild of insects feeding on aphids. Its focus is to understand how natural control works, with the aim to improve it. After the initial two meetings in Czechoslovakia, symposia were organized in Poland, Hungary, France, Belgium, Canada and Portugal. The ninth meeting was held once again in the Czech Republic. Details on history of the meetings, with bibliographic data from all Proceedings, can be found at http://www.aphidophaga.org
