Following detection of currant-lettuce aphid Nasonovia ribisnigri (Mosley) (Hemiptera: Aphididae) in Tasmania in March 2004, surveillance was undertaken in lettuce production areas in New South Wales from March 2005 to October 2006. Regulation of risk produce and education were part of the response. Initial detections were made in January 2006 and surveys ceased in October 2006 after the pest had been detected in most production areas in the State. The survey demonstrated pestfreedom in a progressively declining number of production areas and allowed lettuce trade from aphid free areas to continue with other Australian States sensitive to the pest. Interstate regulation of host produce may have delayed the spread of the aphid, allowing time for the industry to develop strategies to manage the pest.
