Giant vacuum sucks up

bad insects in the patch


O New York Times
Unable to control many resis-
tant pests with poisonous sprays, a
California researcher has invented
a gigantic vacuum cleaner that lit-
erally sucks harmful insects out of
the strawberry patch, leaving most
of the beneficial bugs behind.
The experimental device,
called a Bugvac, cleaned 15 acres
of strawberries last summer and
eliminated the need for conven-
tional insecticide treatments, said
its inventor, Edgar Show, an ento-
mologist.
The Bugvac was called a "posi-
tive step," by Albert Meyerhoff, a
senior attorney with the Natural
Resources Defense Council, an en-
vironmental group.
Show said that California
strawberry growers, who produce
80 percent of the nation's crop, are
looking for new ways to control
insects that have become resistant
to conventional pesticides.
"Strawberry growers are
plagued by three types of bad
bugs," said Show, who works in
the research division of Driscoll
Strawberry Associates Inc. in Wat-
sonville, Calif.
Available pesticides can kill
two of them, the lygus bug and the


western flower thrip, he said, but
they also kill useful insects like
pirate bugs, big-eyed bugs, damsel
bugs, lacewings, predatory mites
and parasitic wasps, that naturally
control insect pests. Moreover,
the third bug, the two-spotted spi-
der mite, is resistant to all chemi-
cal sprays, Show said.
Three years ago Show planted
a patchwork of strawberries ad
flowering plants to see if lygus
bugs might be induced to ea plants
other than strawberries or if natu-
ral enemies to the lygus might be
attracted to a field of mixed plants.
To count all the bugs in the patch-
work, Show used a hand-held Sao-
pling device called a D-Vac. -You
put the vacuum cone over the jlnt
and it sucks up all the bugs into a
net where you can count them," he
said.
The little vacuum sucked up so
many lygus bugs that Driscoll man-
agers instructed Show to build
larger prototypes.
The current version is mount-
ed on a tractor and rolls down the
planted field sucking up bugs,
Show said.
"Each strawberry plant is like
an insect condominium," Show
said. "Fortunately the lygus bugs
live on the roof."
