  1. “Ash tree killer” Emerald Ash Borer (Agrilus Planipennis) Family: Buprestidae (metallic wood borer family) By Adam Jurado

  2. Life Cycle • Hundreds of larvae are laid under tree bark for the winter • Larvae feeds on the tree’s phloem • In June and July, pupation occurs, which can cause the bark to slough off • Newborn females reproduce within a week after birth • 1, 2 and 3 year life cycles are typical

  3. Infested Areas of the U.S. • Northeastern US • Illinois, Wisconsin, Missouri, Michigan, Ohio, Pennsylvania, Maryland, West Virginia, Virginia, New York

  4. Negative Effects • Canopy thinning • Bark sloughing • Money lost for property owners and businesses • Death of the Fraxinus, Pterocarya, Ulmus and Juglans trees • Spread of infestation

  5. Reason for Public Concern • Tens of millions of trees have died • The beetles are monitored by the USDA • Nursery operators, forest workers, municipalities and property owners have lost billions of dollars since introduction of the species

  6. Place of Origin • China, South Korea, North Korea, Japan, Mongolia and Taiwan • The emerald ash borer was carried on boats and airplanes, probably on wood shipping crates • First sighting in the US was in 2002, in southeastern Michigan

  7. Spread of the Borer • The emerald ash borer spreads a half a mile each year, however it can fly 6 miles in 24 hours • After introduction in 2003, the borer has spread throughout Northeastern and North-Central US, and Southeastern Canada

  8. Why the Borer is a Problem • Deforestation • Quarantines by the USDA are inconvenient for when firewood needs to be shipped • Property damage, and spread of the emerald ash borer are hard to control • Every year, the borer expands its domain

  9. Methods of Control • Survey and protection programs • State and local governments are alerted • Fixing the infestation first in populated areas • Killing live ash trees • Quarantines
