Stinging ants aren't all bad,


but don't try to convince Brazil


This will sound like a science
fiction script.
A U.S. Department of Agricul.
luec publication mentions that.
"Millions of aggressive, stinging
ants overran a small city In the
Amazon rain forest, invading
homes. schools, churches and
stores. Nothing seems to stop
them."
But to the people of Envira.
Brazil. it's not a movie, It's real
life.
The U10.000 people who live in
the small riverbank town In the
Amazon rein forest have been
strugglng against a booming popu-
lation of fire ants. This outbreak of
ants wanted several years ago. when
the townspeople noticed tiny, red.
dish.brown ants foraging for food.
After they were unable to control
these ants. the Brazilian govern-

states. had taken over the small
town in the Amazon rain forest.

mologist, said when he got In Envl-

to say that the ants were over-run.

"I found some colonies with
more than a million ants Inside." he
continued. "I have been studying
fire ants for 17 years, and I have
never seen anything like It."

that clearing of the Amazon rain

Ants help enrich the soil


hurricane season, certain species of
insects became more prevalent in
the territory. What does this tell us?
This hurricane season affects the
islands* ecology so much that
insects that you normally hardly see
are more noticeable.
Many people with whom I've
come in contact lately have said
that hey frequently see ants in their
houses. The black ants around your
kitchen are called local sugar ants.
You often find them in your sugar
or eating some sweet thing. Believe
me. any kind of food you leave out
in the kitchen without proper pro-
tection, the sugar ants will find it.
These ants. however, would not run
you out of your house like the fire
ants in Brazil.
We do have stinging ants in the
Virgin Islands, however. These ants
are very aggressive and will deliver
fiery stings. For this reason, many
Caribbean people called them fire
ants. Other names are "biting ants,"
"red ants." "wild ants" and "hormi-
go brava." These ants are some of
the most common pests you find in
the Caribbean.


According to Dr. Walter I.
Knausenberger. an entomologist.
"stinging ants can sting repeatedly
and will vigorously attack things
that disturb them. Their venom is
severely painful to most people and
livestock." Certain people who are
allergy-prone can become sensi-
tized if they got stung repeatedly.
People who are extremely sensitive
may suffer chest pains, nausea or
even lapse into a coma from a sting.
Stinging ants can damage young
plants by gnawing the roots, stalks
and fruits. But stinging ants also are
beneficial to man. They help bury
and transform dead. decaying ani-
mals and plant materials.
They enrich the soil by Increas-
ing the availability of certain plant
nutrients. They also are known to
eliminate certain insect pests in
your garden. Knauscnberger men-
tioned that. "in Puerto Rico. the
brown fire ants have been shown to
destroy over 90 percent of the
potential house fly population by
preying on the maggots and eggs."
The ant population is regulated
naturally by birds, lizards. toads or
