SCREWWORM FLY 2-2-2-2-2-2-2-2-2
LONG OF PLANE
The program, in little more than two years,
has reduced screwworm infestation in the
Southwest by 90 percent. But a live-fly
barrier 100 miles wide is being maintained
along the U-S-Mexico border to prevent
infestation from Mexico. The barrier stretches
from the Rio Grande Valley to Arizona. Planes,
operating out of Del Rio, spread the sterile
flies along the border. A Department of
Agriculture employe rides in each plane,
dropping the boxes of flies at regular
intervals through a chute in the aircraft.
Scientists some time ago learned that the
female fly mates only once in her lifetime.
If she mates with a sterile male, her eggs
do not hatch. If sterile males are scattered
in large numbers over a wide area, the fly
population dies out.
Here’s what’s next.
