Update on exotic ash collection for hybrid breeding and survey for EAB-resistance in native North American speciesThis article is part of a larger document. View the larger document here.
Contrary to the high levels of devastation observed on North American ash species infested with emerald ash borer (EAB) (Agrilus planipennis Fairmaire), reports from Asia indicate that EAB-induced destruction of Asian ash species is limited to stressed trees. This indicates that Asian ash species have co-evolved resistance, or at least a high degree of tolerance, to this insect. We are investigating whether inter-species hybrids between Asian and North American ash species can be used to introgress EAB resistance into native ash species.
