From staff reports
Natural, non-toxic chemicals that plants use
to fight off insects are being scrutinized by a USC
organic chemist.
Thomas Bryson is studying the built-in de
rfenses of certain plants to determine whethei
jhey can be as effective as man-made chemical;
In stopping crop destruction by bugs.
'The strategy for controlling insects is shift
ing to plants to use their own chemistry against
them, said bryson, a USL chemistry protessor
"There is a lot of chemical warfare going on
around various plants, and we seek to exploii
that."
One of the chemical groups Bryson is studying
is derived from a type of moss that resists
bugs and inhibits the growth of nearby plants.
A second plant being studied is used as a hedge
in many Asian countries because cattle won't
feed on it.

"Insect feeding depends on a number of fac:
tors in the food to get the insect to chew and
; swallow the food," he said. "There's a lot of
chemistry that has to be present for the insect
. to eat and graze."
The chemicals that Bryson is working with are
5 called anti-feedants. They make it difficult for
insects to sense a plant as a food source or, in
. other cases, block the normal feeding,
t One well-known anti-feedant is Warburganal,
which is widely used in Africa to control housei
hold bugs and to spice up food.
"People have known about that since the '60s,
at least," Bryson said. "People grind up the root
and disperse the powder around a hut or a
; home to keep the bugs out. It's also used as a
spice that makes things taste hot."
One of the plant chemicals Bryson is working
with may work in a similar way. The natural substance

Bryson is working with two plants to synthesize

"One of our goals is to efficiently make these
materials and similar substances and test them
against various insects," Bryson said. "The hope
is that these chemicals will be close enough to
natural metabolism rather than leaving behind
traces that are poisonous to other plants and
animals."
He said the anti-feedants he's targeting may
have an additional benefit in that they would alter
insect-feeding habits rather than destroy entire
populations, as many insect poisons do.
What remains to be seen is whether insects
develop resistance to the natural chemicals,
Bryson said. A number of similar compounds
might have to be created to extend the lifetime
of each class of anti-feedant, he said. As one

tecting a crop, a new compound would be substituted,
he said.
Bryson is one of a handful of organic chemists
working in this area, but he has contacts with a
number of agricultural firms interested in testing
the natural pesticides as soon as they become
available.
The research recently received a $20,000 grant
from Research Corporation, which USC has
matched, and Bryson said he soon expects results
that could encourage additional funding.
"Because of the difficulty of patenting natural-occurring
materials, the profit potential of this
is somewhat limited," Bryson said. "Anti-feedants
could be important in developing new strategies
to control plant and insect interaction that
would be a lot friendlier to the environment.
Hopefully, these materials won't damage the environment
at all."
