- <p>Officials in the Pacific Northwest fight to repel the Asian
- gypsy moth
- </p>
- <p> Helicopters fanned out over more than 30,000 acres of the
- state of Washington last week in an emergency campaign to repel
- an airborne assault launched from across the Bering Sea. No, the
- ex-Soviet Union had not reconstituted itself and invaded.
- Instead the object of the search-and-destroy spraying mission
- was the Asian gypsy moth, which in its caterpillar stage is
- notorious for devouring the leaves of perhaps 600 varieties of
- trees and shrubs.
- </p>
- <p> At least 35 of the pests entered the U.S. and British
- Columbia last fall, apparently as hitchhikers aboard a group of
- Russian freighters. The newly hatched caterpillars climbed up
- to the highest point on the ship, and were eventually blown to
- shore. Considered far more destructive than the European gypsy
- moth, which annually defoliates 4 million acres in the American
- Northeast, the Asian gypsy moth has decimated millions of acres
- in Siberia and China. Among the reasons: the Asian moths can
- cover 20 miles before laying their eggs. (Females of the
- European variety do not fly.) If the Asian gypsy moth becomes
- entrenched in the Pacific Northwest, the Forest Service
- estimates that the toll on the timber industry could run upwards
- of $35 billion over the next 40 years. By contrast, Washington's
- spray program -- which is scheduled to run about six weeks and
- cover 116,500 acres -- will cost $8.9 million. British Columbia
- has already started spraying, and Oregon has just begun.
- </p>
- <p> The spray being used is not expected to hurt people,
- mammals or birds. It consists of naturally occurring bacteria
- that are lethal only to caterpillars. Some environmental groups
- and residents have opposed the program because the spray will
- eliminate butterflies and other insects as well. But officials
- of the state agriculture departments believe the indigenous
- species will quickly regenerate.
