Bugsling Boogey
Helpful insects may soon have a new way of
getting a free ride into farmers' fields--on a flying saucer. The insects are
small wasps, but they won't sting you!
Instead, they will attack cotton aphids.

Cotton is one of this country's most important
crops.

cotton.
Farmers who free lots of the helpful wasps
in their fields might be able to raise healthy cotton plants without using as
much insecticide. This could help the environment and save money, too.
Learn more about the wasp.
It would take days for farmers to walk all
through their cotton fields and let loose groups of wasps in many different
places. That's why scientists invented the Bugslinger. This cool device flings
small, round disks loaded with wasps. The Bugslinger can fit in the back of a
pickup truck. A farmer could drive around the edge of the field, stopping every
now and then to launch another crew of little wasps.
Do you think the wasps get dizzy, though? If
so, they get over it fast. After all, these insects are found about 100 miles
from Cape Canaveral, Florida. Maybe they were destined to become
astronauts!
The researchers who invented the Bugslinger,
officially known as the "Aerodynamic Transport Body," are Lyle M. Carter
(retired), Joseph H. Chesson and John V. Penner. They work for the Agricultural
Research Service.
They're made of powdered limestone.
Limestone is made up of shells and skeletons of tiny sea animals known as
invertebrates (in-VERT-uh-braits). Probably the chalk in your classroom has
limestone in it.
Water--from rain, sprinklers or irrigation
furrows--eventually causes the limestone disk to break down and get recycled
into the soil.
Now the researchers want to test disks made
out of natural materials that would help the soil, such as compacted peat moss
or manure.
