in the colder parts of the globe. It achieves this in a very unique way. The EAB, during times of cold climate, situates itself in the sapwood of the ash tree. It is here that they stay during winter. During winter EAB accumulates moderately high levels of glycerol in their body fluids. Glycerol is a natural antifreeze agent. The way glycerol works as an antifreeze is by competing for hydrogen bonding with water, which disrupts the crystal lattice formation of ice, unless the temperature is significantly lowered. The temperature at which EAB can actually freeze during winter is very low. Their supercooling point in which they freeze at is negative thirty degrees Centigrade, or negative twenty-two degrees Fahrenheit. If they survive winter …show more content…

She may lay on average seventy eggs, but can lay anywhere from fifty to two-hundred eggs in general, for a four to six week period. A female EAB will not lay eggs on an already inhabited ash tree in which a differing EAB female has already laid eggs upon and can travel up to six and a quarter mile (ten kilometers) to find a uninhabited ash tree. These fertile eggs hatch, on average, two weeks after being laid. This process of emergence and reproduction continues for a total of around sixty-five days, or until the mature EAB die off, since their lifespans one year (Fooy, 2013). Much of this was information was inaccessible to the United States until translation of records began. When the Chinese literature was finally translated, there were obvious red flags that, had we known, we would have taken steps to avoid. In these translated documents, there were ominous notes that North American ashes planted in China were susceptible, and often killed, by EAB, often called Agrilus marcopoli in Chinese literature and Agrilus marcopoli ulmi in Japan (USDA, 2013). It was too late however to stop the invasion that had begun. In East Lansing, Michigan, researches from both the United State and from the
