White Fringetree Hosts EAB

In 2014, researchers at Wright University discovered that the white fringtree (Chionanthus virginicus) was a susceptible host to the emerald ash borer (EAB), in addition to ash (Fraxinus spp.). After further invesitigation, it appears that the white fringetree is just as suitable a host to EAB as any ash species, and that closely related species might be susceptable, as well.

The emerald ash borer was detected in Louisiana in February 2015, and since that time local officials have been working towards a way to control the insect. In a join effort between the LSU AgCenter, the U.S. Forest Service, the Louisiana Department of Agriculture and Forestry, and USDA APHIS, parasitoid wasps have been released in the EAB-positive regions of the state as a means of biocontrol.
