emerald ash borer gallery in white fringetree

Bark removed from a white fringetree reveals the serpentine feeding gallery in the tree’s tissue made by an emerald ash borer (Agrilus planipennis). White fringetree was discovered to be a secondary host of emerald ash borers in North American in 2014, but researchers at Wright State University have found that white fringetrees in low-density ornamental landscapes were not a significant reservoir for emerald ash borer. “Based on our findings, it appears that this species will meet a better fate than most ash trees native to eastern North America,” they report this month in Environmental Entomology.
