"Perhaps no community has suffered more for the sake of a
beetleless world than Sheldon, in eastern Illinois, and adjacent
areas in Iroquois County. In 1954 the United States Department
of Agriculture and the Illinois Agriculture Department began a
program to eradicate the Japanese beetle along the line of its
advance into Illinois, holding out the hope, and indeed the assurance,
that intensive spraying would destroy the populations
of the invading insect. The first "eradication" took place that
year, when dieldrin was applied to 1400 acres by air. Another
2600 acres were treated similarly in 1955, and the task was
presumably considered complete. But more and more chemical
treatments were called for, and by the end of 1961, some 131,000
acres had been covered. Even in the first years of the program
it was apparent that heavy losses were occurring among wildlife
and domestic animals. The chemical treatments were continued, nevertheless, without consultation with either the United States
Fish and Wildlife Service or the Illinois Game Management
Division. (In the spring of 1960, however, officials of the federal
Department of Agriculture appeared before a congressional
committee in opposition to a bill that would require just such
prior consultation. They declared blandly that the bill was unnecessary
because cooperation and consultation were "usual."
These officials were quite unable to recall situations where cooperation
had not taken place "at the Washington level." In the
same hearings they stated clearly their unwillingness to consult
with state fish and game departments.)
Although funds for chemical control came in never-ending
streams, the biologists of the Illinois Natural History Survey
who attempted to measure the damage to wildlife had to operate
on a financial shoestring. A mere $1100 was available for the
employment of a field assistant in 1954 and no special funds
were provided in 1955. Despite these crippling difficulties, the
biologists assembled facts that collectively paint a picture of
almost unparalleled wildlife destruction -- destruction that became
obvious as soon as the program got under way.
Conditions were made to order for poisoning insect-eating
birds, both in the poisons used and in the events set in motion
by their application. In the early programs at Sheldon, dieldrin
was applied at the rate of 3 pounds to the acre. To understand
its effect on birds one need only remember that in laboratory
experiments on quail dieldrin has proved to be about 50 times
as poisonous as DDT. The poison spread over the landscape at
Sheldon was therefore roughly equivalent to 150 pounds of
DDT per acre! And this was a minimum, because there seems
to have been some overlapping of treatments along field borders
and in corners.
As the chemical penetrated the soil the poisoned beetle grubs
crawled out on the surface of the ground, where they remained
for some time before they died, attractive to insect-eating birds.
Dead and dying insects of various species were conspicuous for
about two weeks after the treatment. The effect on the bird
populations could easily have been foretold. Brown thrashers,
starlings, meadowlarks, grackles, and pheasants were virtually
wiped out. Robins were "almost annihilated," according to the
biologists' report. Dead earthworms had been seen in numbers
after a gentle rain; probably the robins had fed on the poisoned
worms. For other birds, too, the once beneficial rain had been
changed, through the evil power of the poison introduced into
their world, into an agent of destruction. Birds seen drinking
and bathing in puddles left by rain a few days after the spraying
were inevitably doomed.
The birds that survived may have been rendered sterile. Although
a few nests were found in the treated area, a few with
eggs, none contained young birds.
Among the mammals ground squirrels were virtually annihilated;
their bodies were found in attitudes characteristic of
violent death by poisoning. Dead muskrats were found in the
treated areas, dead rabbits in the fields. The fox squirrel had
been a relatively common animal in the town; after the spraying
it was gone.
It was a rare farm in the Sheldon area that was blessed by the
presence of a cat after the war on beetles was begun. Ninety
per cent of all the farm cats fell victims to the dieldrin during
the first season of spraying. This might have been predicted
because of the black record of these poisons in other places. Cats
are extremely sensitive to all insecticides and especially so, it
seems, to dieldrin. In western Java in the course of the antimalarial
program carried out by the World Health Organization,
many cats are reported to have died. In central Java so
many were killed that the price of a cat more than doubled.
Similarly, the World Health Organization, spraying in Venezuela,
is reported to have reduced cats to the status of a rare
animal.
In Sheldon it was not only the wild creatures and the domestic
companions that were sacrificed in the campaign against an
insect. Observations on several flocks of sheep and a herd of beef
cattle are indicative of the poisoning and death that threatened
livestock as well. The Natural History Survey report describes
one of these episodes as follows:
The sheep ... were driven into a small, untreated bluegrass
pasture across a gravel road from a field which had been
treated with dieldrin spray on May 6. Evidently some spray
had drifted across the road into the pasture, for the sheep began
to show symptoms of intoxication almost at once ... They
lost interest in food and displayed extreme restlessness, following
the pasture fence around and around apparently searching
for a way out ... [They] refused to be driven, bleated almost
continuously, and stood with their heads lowered; they were
finally carried from the pasture ... They displayed great desire
for water. Two of the sheep were found dead in the stream
passing through the pasture, and the remaining sheep were repeatedly driven out of the stream, several having to be dragged
forcibly from the water. Three of the sheep eventually died;
those remaining recovered to all outward appearances.

Incidents like the eastern Illinois spraying raise a question that
is not only scientific but moral. The question is whether any
civilization can wage relentless war on life without destroying
itself, and without losing the right to be called civilized.
These insecticides are not selective poisons; they do not
single out the one species of which we desire to be rid. Each
of them is used for the simple reason that it is a deadly poison. It
therefore poisons all life with which it comes in contact: the cat
beloved of some family, the farmer's cattle, the rabbit in the
field, and the horned lark out of the sky. These creatures are
innocent of any harm to man. Indeed, by their very existence
they and their fellows make his life more pleasant. Yet he rewards
them with a death that is not only sudden but horrible.
Scientific observers at Sheldon described the symptoms of a
meadowlark found near death: "Although it lacked muscular
coordination and could not fly or stand, it continued to beat its
wings and clutch with its toes while lying on its side. Its beak
was held open and breathing was labored." Even more pitiful
was the mute testimony of the dead ground squirrels, which
"exhibited a characteristic attitude in death. The back was
bowed, and the forelegs with the toes of the feet tightly clenched
were drawn close to the thorax ... The head and neck were
outstretched and the mouth often contained dirt, suggesting that
the dying animal had been biting at the ground."
By acquiescing in an act that can cause such suffering to a
living creature, who among us is not diminished as a human
being?
