Controlling Pests with IPM
saves money as well as protecting the
environment at both Carver Orchard and Shelburne Farm in
Stow. IPM is an ecologically-based approach to pest control,
combining several different techniques to maintain pests below
damaging levels with little or no spraying.
The ladybug is the IPM apple farmer's
friend. Ladybugs and their larvae are voracious predators
and their favorite meal is aphids. Each ladybug can devour over
5,000 aphids during its lifetime. IPM uses natural predators like
The Codling Moth, shown here, is
controlled without spray with IPM. Male moths are attracted
to a perfume the female moths give off. To fool the
male, IPM farms hang dispensers of the perfume all over the
orchard. With the odor everywhere, the males are unable to
find the females, no mating takes place, and the females don't lay
eggs in the apples.
Apple Maggot Flies are attracted to traps
with color and odor, and then trapped on sticky paper. Tarnished
Plant Bugs are controlled by delaying mowing the fields.
This keeps other foods available that the bugs prefer to apple
blossoms. These IPM methods are described by West
Meadows Farm in Vermont.
