 This two-day meeting of the IOBC sub-group, held at the Research Institute of Organic Agriculture (FiBL) in Frick, Switzerland, on 15 and 16 March, attracted 48 people from 10 nations. Dr Bernhard Spieser of FiBL was the local organiser. The 33 papers (19 oral and 14 posters), from researchers in institutes, universities and industry, covered the following topics: Sampling techniques - Francois Calame, Nyon, and Christoph Hogger et al. (Zurich, Bern, & Basel). DNA techniques for separating slug species - Martin Voss et al. (Monsanto and Gottingen). Slug behaviour - including effects of anti-feedants (Albert Ester & R Trul, Lelystad), nematode parasitisation (Bill Bailey & Richard Latham, Manchester) and olfactory orientation (Constanze Kukuck & Hans-Jurgen Schnorbach, Dusseldorf & Bayer AG). Damage forecasting - Andre Chabert (ACTA, Lyon). Population dynamics - David Bohan (IACR-Long Ashton); Mark Shirley (Newcastle); Birgit Grimm (Graz). Effects of damage - Albert Ester & R Trul (Lelystad). Carabid beetle predators and slug populations - J Auger (Tours) and S Briot (Orleans) et al.;Jacqui Mair (Newcastle); Andrew McKemey et al. (Cardiff & IACR-Long Ashton); Bill Symondson (Cardiff). Wildflower strips, field margins and slug populations - Tom Briner & Tom Frank (Bern); Richard Zweifel (Baar). Influences of weeds on slug damage - Mario Barone & Tom Frank (Bern). Biological control using slug-parasitic nematodes - Mischa Aalten (IACR-Long Ashton); Martin Andermatt, Franz Bollhalder and Markus Zuber (Biocontrol AG); Jose Castillejo et al. (Santiago de Compostela and Navarra); Colin Denholm et al. (IACR-Rothansted); David Glen (IACR-Long Ashton); Bernhard Speiser & Johann Zaller (FiBL). A new strain of Beauvena bassiana pathogenic to slugs - Nikolai Geshtovt (Almaty, Kazakhstan). Plant-derived antifeedants - Catherine Dodds (Cardiff). Tests of new bait pellets for slug control - Kresten Christensen (Lonza AG); Andreas Prokop (Neudorff GmbH). Tests
of compounds against slug eggs -
Javier Iglesias et al. (Santiago de Compostela). The meeting was preceded by an exhilarating visit to the Alps at Murren and ended with a visit to Andermatt Biocontrol AG in Grossdietwil, where Dr Martin Andermatt and his colleagues showed participants around the facilities of this successful and expanding biocontrol business selling a wide range of products some of which are produced on-site and others which are bought from other companies. The product range includes slug-parasitic nematodes (Bioslug®, produced by MicroBio Ltd) and slug fences for preventing movement of slugs into treated areas. At the end of the first day, there was a brief tour of the research station's farm. The next meeting will be held between October 2000 and March 2001. David Glen,IACR-Long Ashton Research Station.
