Towards understanding the genetic mechanism of Brassica napus resistance to cabbage stem flea beetle (CSFB)

Abstract: The Cabbage Stem Flea Beetle (CSFB), Psylliodes chrysocephala, is a major pest of
winter oilseed rape (OSR; Brassica napus) in Europe. Since the ban of neonicotinoid pesticides by the European Union, CSFB pressure on OSR has increased significantly and has led to substantial crop damage, compromising both establishment and yield. With the removal of chemical control methods, plant resistance offers a promising approach for managing CSFB however, the presence and mechanisms of resistance in OSR are poorly understood.
