ARS Symposium Addresses Invasive Species
By Hank Becker
February 11, 2000
Thwarting alien invasive species--a
growing challenge for researchers--will be the subject of a Feb. 15 symposium
sponsored by Agricultural Research
Service laboratories at Beltsville, Md.
The symposium will address current and future research efforts to combat
these invaders and lessen the damage caused by those already here, according to
ARS entomologist Michael
E. Schauff. He's based at the ARS Systematic Entomology Laboratory at
Each year, American farmers and homeowners spend millions of dollars
combating fungi, weeds, insects, nematodes and other alien organisms that have
been introduced into the United States from foreign countries. With the
increase in international commerce and trade, the number of alien species
entering and becoming established in this country is growing every year.
Last year's invaders include Paracoccus marginatus, the papaya
mealybug from Mexico that damages papaya and cassava, and Oidium
lycopersici, tomato powdery mildew from Europe that can devastate
commercially grown greenhouse and cultivated tomatoes.
The Beltsville scientists will discuss their ongoing research aimed at
solving the problem of invasive species and lessening their impact on America's
food and fiber supply. Guest speakers will focus on global and national
perspectives. Afternoon sessions include demonstrations of laboratory
activities highlighting research addressing specific invasive species problems
Sessions begin at 8:30 a.m. and end at 11:45 a.m. Research demonstrations
run from 1:30 to 4:00 p.m.
ARS is the chief research agency of the U.S.
Department of Agriculture.
