Trade Increasing Number of Exotic Species

Exotic insects and diseases that attack plants can be very destructive and
cost millions of dollars to fight. Just ask those cities fighting the
invasion of the emerald ash borer and the Asian longhorned beetle. The
Great Lakes Radio Consortium’s Rebecca Williams reports… a recent
study looks at where new potential pests are coming from:


Inspectors at airports, ports and borders nab between 40 and 60 thousand
different potential plant pests each year. That’s according to a study in
the journal, Biological Invasions.


Author Deb McCullough says global trade is leading to an increase in the
number of non-native insects and diseases that could become problems.


“China in particular which has become one of our major trading
partners…most of the kinds of climate that you’ll find in China, you’ll
find somewhere here in the U.S., and there’s really an awful lot of
opportunities for exotic insects to become established here.”


McCullough says it’s hard to estimate how many new potential pests
could be slipping past inspectors. She says at best, inspectors go through
just 2% of agricultural cargo coming into the U.S. each year.

Some Success in Non-Native Beetle Fight

The City of Chicago and the U.S. Department of Agriculture

The City of Chicago and the U.S. Department of Agriculture are celebrating a small victory in their battle against an invasive pest. The Asian Longhorned Beetle arrived from China and is responsible for destroying thousands of hardwood trees in North America. The Great Lakes Radio Consortium’s Shawn Allee has more.


Chicago saw its first Asian Longhorned Beetle back in 1998. USDA and Chicago officials quickly destroyed more than fifteen hundred trees to stop the infestation. They also slapped a quarantine on the historic Ravenswood neighborhood, which prevented residents from removing tree cuttings from the area.


Now officials are lifting those restrictions, saying no one’s seen the bug in the area’s stately tree canopy for nearly two years. Joe McCarthy is the City of Chicago’s chief forester. He says a beetle hotline and a diligent press made the difference.


“There’s so much coverage of this thing, that the beetle is on TV, out in the papers, on front pages. And that’s how all the main infestations were found in the Chicago area.”


McCarthy points out that another Chicago neighborhood is still under quarantine.


The USDA is also fighting the Asian Longhorned Beetle in New York City and parts of New Jersey.

Foresters think they might be on the verge of eradicating a pest that destroys trees. The Great Lakes Radio Consortium’s Lester Graham reports.


The Asian long horned beetle attacks maples and elms. The bug first appeared in 1996, after wood crates infested with the beetle were shipped to New York from China. A second infestation appeared in the Chicago area in 1998. Stan Smith is a manager of the tree nursery program for the Illinois Department of Agriculture. He says the Asian long horned beetle might be under control around Chicago.


“Our population, we feel, is small enough that it might be getting to the point where it might not be able to reproduce very well. Hopefully within four to five years we’ll have everything pretty well cleaned up. At least that’s what we think can happen.”


The beetle is more widespread in New York, but fortunately the insect can’t fly very far. That means it can’t spread quickly, giving foresters a better chance at eliminating the pest.
