Abstract
Long-term monitoring in Michigan and several northeastern states has documented increasing parasitism and reduced EAB attack rates. Ash regeneration is currently benefiting from releases of introduced parasitoids, which now cause 20-80% parasitism of EAB larvae in ash saplings (1-2 inch dia.) and young trees (5-8 inch dia.).
