Abstract

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.
