Abstract Details

2020, Master of Science (MS), Wright State University, Biological Sciences.
Ornamental white fringetrees in IL, IN, OH, and PA were reassessed in 2018 as a follow-up study to determine the fate of the white fringetree through the invasion wave of emerald ash borer. Attack rates decline by half from 2015-2018 and only 13% of trees were infested. Health of not reinfested trees in 2018 improved suggesting resilience against EAB attack whereas currently infested trees in 2018 displayed signs of declining health. Trees differed in their resistance to EAB attack and 41 additional ornamental and wild white fringetrees were studied in OH to determine if the anti-herbivory defense chemical, oleuropein, influenced EAB larval performance. Due to low attack rates and tolerance to EAB attack, white fringetrees are likely going to survive the invasion wave. Oleuropein concentrations were not correlated to larval performance, but oleuropein concentrations were higher in uninfested and ornamental trees suggesting genotypic and phenotypic variation among white fringetree genotypes.
