SECOND INTERNATIONAL SYMPOSIUM ON BIOLOGICAL CONTROL OF ARTHROPODS DAVOS, SWITZERLAND SEPTEMBER 12-16, 2005 USDA Forest Service Publication FHTET-2005-08 ___________________________________________________________________________________ SECOND INTERNATIONAL SYMPOSIUM ON THE BIOLOGICAL CONTROL OF ARTHROPODS The Second International Symposium on the Biological Control of Arthropods held in Davos Switzerland builds upon the foundation laid at the first meeting in Hawaii in January 2002. The intent of the ISBCA meetings is to create a meeting for practitioners, a forum for infor- mation exchange, an event to build cohesion among the research community, and to foster discussions of issues effecting biological control work, particularly pertaining to the use of parasitoids and predators as biological control agents. To this end, a 14 session conference with invited has been designed to address the most interesting and relevant research topics that have broad international application. The oral sessions have been complimented with unsolicited poster presentations prepared by over 100 different scientists from around the world. Topics covered at ISBCA II are diverse and in- clude invasion biology and application to biological control, biological control of arthropod pests of conservation importance, the role of biological control for pest management in devel- oping nations, and emerging experimental protocols and legislation for assessing natural en- emy specificity and safety. The printed ISBCA II conference proceedings are large, indicating the great interest in the content of this meeting. The two volume proceedings only include the articles prepared by invited speakers. The accompanying CD has an electronic version of the conference pro- ceedings and the abstracts of approximately 115 posters that were presented at the meeting III and perused by over 200 meeting attendees representing the international biological control community.
