Research Highlights

Assessing the Role of a Little-known Wood-boring Beetle in Sugarberry Decline (2019)
SRS-2019-66 Ongoing research seeks to explain an ongoing, severe episode of sugarberry mortality in the southeastern U.S. A rarely collected species of buprestid beetle, Agrilus macer, is attacking dying trees at high densities. USDA Forest Service research results suggest that Agrilus macer is a secondary pest, rather than a primary cause of mortality, and there is no evidence that it is the vector for harmful pathogens.
