Termites Find New Bio-Pesticide Tough To Swallow
Subterranean termites commonly found in the southwestern United States may now soon have a new bio-pesticide to fear, thanks to the U.S. Department of Agriculture (USDA).

According to PCT Online, (September 25, 2000), USDA microbiologist Maureen Wright has been testing molds and other microbes that will kill Formosan subterranean termites, while sparing beneficial insects.  Wright's research is part of "Operation FullStop," a national campaign implemented by the USDA against the Formosan termite.  Latest studies revealed that the mold growing at Wright's research center killed 100 percent of termites in less than one week, compared to only 50 to 100 percent killed in one or more weeks by four other common fungal species.

The USDA is looking into developing a cost-effective method for producing the mold as well as various formulations with which to apply it.  In addition, Wright plans to test other strains of the mold.

The Formosan termite is the most destructive wood destroying insect, due to their large size and aggressive breeding habits.  Since a Formosan termite colony can consist of 350 thousand to 2 million workers, it's no wonder that in New Orleans, Louisiana alone, Formosan termites cost the city up to $300 million a year.
