+++++++++++++++++++++++++
The Board of BioProspect is pleased to announce that it has developed
a novel application for a plant extract that has shown significant
activity for the control and treatment of termites. Code named AP778,
the extract is sourced from a species of a native Australian tree.
AP778 is the second major discovery for BioProspect's burgeoning
natural agrochemical portfolio and should not be confused with Qcide,
the natural insecticide discovered by BioProspect last year.
Termites are a major problem around the world as they feed on wood
and are responsible for the destruction of building structures,
typically houses. It is estimated that termites are responsible for
over $750 million damage per year to US households alone.
Control techniques for termites are generally divided into two types,
prevention and treatment.
Tests to date show opportunities for AP778 to be used against
termites in the following manner:
* Repellant barrier - applied to the outer surface of, or in the soil
surrounding the structure to be protected (prevention).
* Wood treatment - sprayed onto or impregnated into building material
to prevent termite attack (prevention).
* Direct contact - eg for house incursions, treatment of termite
colonies (treatment).
The individual components in the plant extract that contribute to
each of these applications have been isolated and their chemical
structures determined.
BioProspect has lodged a provisional patent covering the use of AP778
as a repellant, an antifeedant (reduces or prevents normal feeding,
leading to death), and as a direct contact termiticide.
AP778 is unique, through its multi-action effect on termites, unlike
existing products on the market.
The agrochemical termiticide market has been searching for a
chemical to replace the organochlorine insecticides that were
largely withdrawn from the Australian market in 1995 because of their
negative environmental effects. The current widely-used chemicals
such as chlorpyrifos are not as effective as the organochlorines as
they do not provide the longevity of protection of their
predecessors, and have to be handled with caution because of the
acute neurotoxicity. The market is seeking a natural alternative to
existing products.
World-wide sales of termiticide products are extensive. It is
estimated that expenditures on termite control exceed US$l billion
per annum in the US alone.
BioProspect is currently in negotiations with international
agrochemical companies for the licensing rights to AP778. The Company
anticipates concluding these negotiations in the near future.
