Emerald Ash Borer EAB

PSU Ornamental Entomology 

First found in PA in Butler County in June 2007. In Feb 2009 present in Mifflin County, central PA, in addition to sections of western PA. First noted in the U.S. in Michigan in June 2002 and has now killed 40 million trees in MI, IL, IN, MD, OH, and PA. Unknown source of EAB but may have come in ash wood in cargo ships or in packaging of consumer goods.

The native range of EAB is eastern Russia, northeast China, Japan, Korea, Taiwan, and Mongolia.  

All species of ash in the plant genus Fraxinus and their cultivars appear to be susceptible to EAB in North America.  It does not attack mountain ash in the plant genus Sorbus

Growing Degree Days

Average daily temp minus baseline temp of 50° beginning 1 March. Degrees above 50° is cumulative through the season. Negative numbers are ignored. Ex. 80° high + 60° low for a particular day, divided by 2 = 70 – 50 = 20° days for that day. The number is used to predict plant and insect development under normal growing conditions. Unseasonal drought or disease would affect the results.

 

Daily PA Regional Growing Degree Days – PSU; take number from this chart to use with following chart to help determine insect’s life cycle and possible control measures.
