Film Prelude: Scope of the Problem (01:29)
Some of America's most treasured trees hide one of the world's most invasive species. Invasive species have no natural enemies in the new territory and thus are not kept in check.
First Appearance of Invasive Beetle (01:56)
In the global economy, exotic animals, plants, and insects are imported along with goods. Invasive species cause the U.S. over $120 billion per year. In 1996, the Asian longhorned beetle made its first appearance in New York City.
Strange Beetle (01:14)
When an unidentified beetle makes its appearance in New York City, entomologists try to search for its source.
Destructive Force of Invasive Beetle (02:15)
The Asian longhorned beetle is one of Asia's most destructive pests. These beetles have the potential to destroy one-third of America's trees because they invade many types of hardwood trees.
High Cost of Tree Removal (01:54)
In 2008, Asian longhorned beetles are discovered in Worcester, MA. In 2009, the USDA removed more than 25,000 host trees from the area at a cost of $24 million.
How a Beetle Damages a Tree (02:58)
The Asian longhorned beetle is extremely destructive. Beetle larvae burrow deep within a tree to feed on its food and water conducting vessels, causing structural defects that eventually kill the tree.
History of Beetle's Journey to America (02:57)
The Asian longhorned beetle probably made its way to America in wood products from China. An aggressive eradication program near the Berkshires might keep the beetles out of the forests.
Massachusetts Infestation (01:51)
USDA scientists in Massachuetts are using a tree's own physiology to deliver insecticide.
Environmentally Safe Eradication Methods (01:31)
Scientists at a quarantine laboratory say that the key to controlling the beetle may be found in dirt. They seek environmentally safe eradication procedures.
Quarantine Areas (01:28)
By studying infestation evidence in trees, ecologists determine how long ago the first beetle eggs were laid and how fast the infestation will spread through a particular area. This helps determine size of quarantine areas.
Tree Survey Process (01:27)
One mile from the core of an infestation, a survey process involves inspectors going into the field, identifying, cataloging, and examining all host trees in a geographic area.
On the Lookout for Invasive Beetle (02:11)
After an article appeared in "Smithsonian," calls came in from other areas where Asian longhorn beetles were suspected. The beetle has been stopped at ports of entry in 15 states.
