Plain Language Summary

This book is the fifth in a series summarizing biological control programmes against insects and weeds in Canada and covers the period 2001 to 2012. In Chapter 9 we discuss efforts currently underway to find suitable biological control agents for emerald ash borer. This invasive alien pest, first detected in North America in 2002, poses a significant threat to native ash populations. Systemic insecticides of botanical origin are available for treatment of individual, high value trees, but control agents for widespread use are lacking. Three species of parasitoids discovered in China have been released into the wild in the US and petitions for their release in Ontario are being prepared. Surveys have identified some native parasitoids that may have potential. The native fungus Beauvaria bassiana was tested in a southern Ontario field trial. Other potential pathogens include a species of nematode that infects the emerald ash borer and a microsporidia from the bronze birch borer.
