Dear colleagues, The deadline has been extended until 31 December 2018. The next International Congress of Entomology will be held in Helsinki, Finland in 2020 July 19-24 (http://ice2020helsinki.fi/) We have been asked to organise the "Forest and Urban Landscape Entomology" section, where a number of symposia can be accommodated. We are inviting proposals for symposia with topics that would fit in this section. Symposium presentations will be 15 minutes each (including time for questions), allowing for the possibility of one ‘double-presentation’/keynote talk of 30 minutes (i.e. 20 minutes for the talk and 10 minutes for questions/discussion). There will be eight presentations per symposium (or seven if a keynote talk is included). Proposals to organize a symposium at ICE2020Helsinki should be submitted by the on-line submission system ( https://submit.peerageofscience.org/conference/ICE_2020) Proposals should include a brief background/justification, the names of the organizers, a preliminary list of potential speakers, and any other relevant issues. Deadline: 31 December 2018 Guidelines for proposing symposia are at our website, link: https://ice2020helsinki.fi/call-for-symposia/ Symposium proposals are submitted via our on-line system, link at our website: https://ice2020helsinki.fi/ PLEASE follow updates concerning ICE2020helsinki at our website: https://ice2020helsinki.fi/ Andrea Battisti, Nathan Havill, Dmitry Musolin, Heli Viiri, the "Forest Entomology and Urban Landscape" section conveners.
