Environmental Resources, a
long term control must
eventually come about
through biological control
efforts such as the im
portation of natural
predators for these moths.
(Smce they were originally
foreign to the environment,
their natural enemies must
be imported from Europe
and other parts of the
world.) „
Although this process is
working, the government
also does aerial spraying of
insecticides in high-use,
forested, residential, and
recreational areas as a type
of nuisance control.
“We do not do massive
aerial spraying,” notes Bill
Shppey. “We keep the spray
blocs as small as possible
with a very narrow buffer.
That way there is some
migration activity, and
should a virus take place, the
migrating caterpillars would
spread the spores. When a
general collapse occurs, it
goes into the spray blocs.”
There are several other
reasons behind using very
small spray blocs. Very
dense populations of gypsy
moths are susceptible during
the fifth and sixth mstars (an
instar is the tune between
larval molts) to a virus, to a
bacteria, and to starvation.
Therefore, they have a
natural population check.
Critics of the spraying
program have said that

Gypsy moths
large scale spraying
prevents the natural control
from operating smce it has
the effect of thinning out the
population to a level at which
it is less vulnerable to in
fectious epidemic diseases.
Another reason for using
only small spray blocs is one
of economics. Spraying is
just too costly. The contract
costs of spraying this year
are $7.09 per acre. A total of
137,000 acres was scheduled
for treatment with a price
tag of $972,000.
The Bureau does not begin
to approach the spraying as
eradication because of the
above reasons and several
others. First of all, says
Slippey, to eradicate the
gypsy moth in Pennsylvania,
all the infested areas around
the state would have to be
treated. That amounts to
approximately one half the
Commonwealth. Also, the
building dynamics of the
gypsy moth are such that if
no caterpillars are
destroyed, the insect will
multiply 200 fold. (One
female lays approximately
400 eggs in a sac with a sex
ratio of 50/50.) Therefore,
in order to keep the
population steady, 97 per
cent must be lolled each
year. Anything less than that
and the population will in
crease.
To add to the problem, the
gypsy moth has a delayed, or
staggered, hatch. Therefore,
spraying would have to be
repeated several times to be
Lancaster Farming, Saturday, June 10,1978—37
sure all the gypsy moths
were killed.
At this point, natural
predators, or parasites of the
gypsy moth have a
cumulative effect of killing
80 per cent of the insect
population each year. High
residential, recreational,
and high-use forests are also
sprayed.
The insecticide used is
Dylox, which has been found
to be the safest type of spray
which can be used to combat
these msects. This'material
causes no adverse effects to
humans, pets, property, fish,
game, and to most desirable
insects such as many
aquatic organisms and
honey bees It is, however,
on the Russell Train list of
100 questionable products
with a danger cited as
cancer causing.
Spraying, which is just
being completed in the
Commonwealth this week, is
tricky. The insecticide is
sprayed onto the trees, so
that when the caterpillars
eat the leaves, they injest the
material which is poisonous
to them.
The tuning of the spraying
program is critical, because
the foresters must wait for a
complete hatch and enough
leaf surface to be effective.
If they wait too long/they
need more chemicals with
less leaf surface. As a result,
they have only seven to 10
days, approximately, to
apply the insecticide in order
to do a good job.
In the past, 90 per cent of
the spraying has taken place
m new areas each year.
“We don’t spray the
second year unless it is
absolutely necessary,” says
Slippey.
Thus year the spraying

began in Cumberland and
Perry Counties and then
moved to Chester, Lebanon,
and Lancaster. When
completed, the pattern will
include 24 counties where the
gypsy is a serious problem.
Five contractors were
involved in the work:

from Oregon; Island
Helicopters Inc., New York;
Helicopter Applicators, Inc.,

Dick’s Air Service, Inc.,

According to Slippey, the
outlook for control of the
gypsy moth is hopeful, but he
added, “We are going to be
involved in spraying each
year for several more
years.”
“The amount of spending
is determined by the state
legislature,” he points out.
“Many years we could have
used more, but it really
depends on how much the
people demand funds for the
program.”
“We’re never going to be
rid of the gypsy moth,” he
continued. “Just how long it
will take until they become
naturalized is a good
question. I hope some day we
reach that point.”
Until then, precautions
can be taken by all in
dividuals to help prevent the
spread of gypsy moths.
Since the female gypsy
moth is flightless, she crawls
into upright objects to lay
her eggs in July and early
August While the trunks of
trees are the usual egg
laying sites, camping
trailers, house trailers, cars,
nursery stock, packing
crates, and other movable
objects serve, as well. Thus,
