Biocontrol Tour of Ontario,
Canada
Sponsored by:
New York State Integrated Pest Management,
New York Farm Viability Institute,
and New York State Flower Industries
Say it with flowers - The tour got started with a visit to the Erie Basin Flower Trials in Buffalo
Write that
down
Lots of
information
from Albert
Grimm at
Jeffery's
Greenhouses
Early
flowering
mums are
used as a
trap plant
for thrips at
Boekestyn
Greenhouses
ID is essential!
Gotcha
Trap crops can
be used as a
distribution
point for
beneficial
insects, in this
case the thrips
predator
Amblyseius
swirskii
They're tiny
but fast
Looking at A.
swirskii
predatory mites
at Boekestyn
Greenhouse
with Ed
Boekestyn
Green jungle - Biocontrol works for greenhouse vegetables, too.
Mike Short,
of
EcoHabitat
AgriServices
explains the
use of
Banker
Plants at
Waldan
Gardens
Bob
Newhouse
produces his
own banker
plants and
infests them
with bird
cherry oat
aphids as a
food source
for the
parasitoid
Aphidius
colemanii
Wasps you want
These Aphidius
wasps fly
throughout the
greenhouse
searching for
aphids to
parasitize.
Eggplants
make good
whitefly trap
plants in the
poinsettia
crop at
Ravensbergen
Greenhouses
Hey, over here!
Yellow pots and
eggplants are
attractive to
whitefly. Encarsia
formosa and
Eretmocerus
eremicus are used
to control them at
Jeffery's
Greenhouses
Ask the
expert
Graeme
Murphy of
OMAFRA in
Ontario
shows
growers
parasitized
whitefly
pupae on
eggplant
leaves
Can you see it?
Minute plant
bugs (Orius
species) can
come in
through open
windows and
help out with
pest control
Lots of places
to hide
Orchardcreek
Greenhouse
uses
biological
control to
manage
several pests
in their cut
gerbera crop
Beneficial
beetle
Delphastus
beetles will
feed on all
stages of
whitefly
An
impromptu
stop at the
Stokes plant
trials in the
Niagara
Peninsula
gave us a
chance to
stretch out
legs and
minds
Mark Yadon
described the
many
biological
control
methods
used at
Mischler's
Greenhouse,
a retail
operation
with a wide
range of
crops.
Slow but
steady
Slow release
packets of
Amblyseius
cucumeris
include an
additional food
source for the
predatory
mites so that
the population
can increase in
the
greenhouse
One stop
shopping
This plant has it
all - cards with
Encarsia pupae,
corn cob grits on
the leaves used to
apply spider mite
predators, a
sachet at the top
left for thrips
predators, and a
small canister
that was used to
hold another type
of whitefly
parasitoid.
Research in
practice
Carol
Glenister
describes a
research
project she
is running
at
Mischler's
greenhouse
Grower to
grower
One of the
purposes of
the tour was
to help
growers help
each other
implement
biological
control in
their own
greenhouses
