BT-BASED
BIOPESTICIDE FOR FIRE ANT CONTROL
The
red imported fire ant is a pest in both urban and rural areas. The
ant directly affects people, animals and plants (crops). Furthermore,
the ant causes indirect problems through its effects on the industrial
and commercial infrastructure and the ecosystem. Damage estimates
for the US vary from millions to billions of dollars annually across
the imported fire ant's geographical range. A recent veterinary
survey provided evidence that the beef cattle industry in Texas
alone suffered losses estimated at $67 million. Hundreds of
millions of dollars are spent annually for control of the fire ant.
The
main insecticides for fire ant control are organic compounds, all
of which are designated as PAN Bad Actors, i.e., chemicals that
are one or more of the following: highly acutely toxic, cholinesterase
inhibitor, known/probable carcinogen, known groundwater pollutant
or known reproductive or developmental toxicant.

Fire Ant Queen Surrounded by Workers, Brood
and Eggs
Scientists
at Biological Targets, Inc. have purified an insecticidal protein
toxin from a new strain of Bacillus thuringiensis (Bt) that kills
the red imported fire ant. A formulation based on this new
strain of Bt represents a new environmentally safe insecticide,
called ANTi â„¢, with tremendous potential for controlling a very
important pest insect in the US and throughout the world.
