Proceedings of the 6th Pacific Rim Conference on the Biotechnology of Bacillus thuringiensis and its Environmental Impact

Guest-edited by Jean-Charles Côté, Imre S. Otvos, Jean-Louis Schwartz and Charles Vincent

The 6th Pacific Rim Conference on the Biotechnology of Bacillus thuringiensis and its Environmental Impact was held in Victoria, British Columbia, Canada, from October 30 to November 3, 2005, for the first time on the east side of the Pacific. Previous conferences were held in Taipei (Taiwan) in 1994, in Chiang Mai (Thailand) in 1996, in Wuhan (China) in 1999, in Canberra (Australia) in 2001 and in Hanoi (Vietnam) in 2003. All these past international meetings proved to be great successes. They brought together scientists from various countries with diverse, and often specific problems, priorities and approaches to the use of Bt, but sharing same interests and complementary expertises. They provided a unique platform to review and present new research results of both fundamental and practical nature, to discuss new trends and issues related to Bt science, Bt products and Bt uses worldwide. The Victoria Conference continued this tradition and offered updated, significant contributions to sound science, transparent communication and critical appraisal of the continuing progress experienced by the Bt  field.
