Insect Growth
Insect growth-regulators,
or hormone-mimicking
compounds, may help rid
catttle of flies that cause
major losses in milk
production as well as
reduced gains in weight of
beef animals, according to
results of tests reported by A
U.S. Department of
Agriculture (USDA)
scientist here recently. •

portant from the standpoint
of disease prevention as well
as the pests’ nuisance factor,
whjch has been estimated to
cause losses exceeding $5OO
million annually in reduced
production of milk and meat.
Experiments with syn
thetic mimics of natural
juvenile hormones of flies
were described in a talk at
the Eastern Branch Meeting,
Entomological Society of
America, by Or. Richard W.
Miller, an animal scientist of
USDA’s Agricultural
Research Service, Beltsville,
Mexican Beetle
Infests Soybeans
Heavy infestations of
Mexican Bean Beetles in
soybeans have been reported
on the Eastern Shore and
Southern Maryland, says the
Maryland Department of
Agriculture.
The State agriculture
agency here has received
reports that some fanners
are applying or hiring
custom applicators to apply
the chemical dimethoate,
commonly known as Cygon
or De-Fend, for the control of
this insect on soybeans.
Ronald Johnson, Director
of Plant Industries Division,
says that this chemical is not
registered for use on
soybeans by the En
vironmental Protection
Regulators For Cattle Production
Md. He incorporated the
compounds in cattle feed;
they passed through the
animals' digestive system,
permeating the manure, a
prime material for thfe flies’
development. At critical
periods, hormones are
necessary for the continued
development of fly larvae
and pupae. When present at
the wrong time, however, the
hormone dooms the im
mature insect to remain at
that stage of development
until it dies. ARS chemist
Meyer Schwarz synthesized
one of the most promising
Agency and, thus, it is a
violation of the law to use it
on that crop. He warns both
custom applicators and
fanners that there may be
serious consequences from
illegally using this product.
Applicators could lose their
licenses if convicted of ap
plying the material since it is
not labeled for this use.
Fanners would be subject to
having their crop destroyed
if illegal residues were
found by the Food and
Drug Administration.
Since the Mexican Bean
Beetle will cause little
damage to the soybeans,
unless defoliation exceeds
25-30 percent, farmers are
advised against spraying in
many instances. If
defoliation exceeds 25-30
percent, Johnson suggests
spraying with carbaryl,
commonly known as Sevin,
or malathion. Both of these
products arc registered for
this use by EPA and are
recommended by the

hormone mimics tested by
Dr. Miller.
Horn flies and face flies
are a problem in pastures
rather than bams and thus
are particularly goad targets
for growth-regulators.
Moreover, it would be im
practical to spray pastures
to control these pests.
Removal of the manure
would be equally unfeasible.
“Integration of growth
regulators with sanitation
and traditional insecticides
offers the best potentials for
control of flies,” Dr. Miller
said. “Our tests demon
strated that house flies and
stable flies find alternate
breeding places such as
untreated wet straw bed
ding, and thus could remain
a problem when growth
regulators are used alone.”
' Dr. Miller also briefly
described research with the
sex attractant of the face fly.
Hormonal compounds of
the type being tested by ARS
have been shown to readily
breakdown in the en
vironment. The ex
periemental growth
regulators tested by Dr.
Miller are not registered for
use as feed additives. Ap

Service. These materials
would also be effective
against the corn earworm
and green clover worm,
which may be attacking
soybeans at this time.
Seek the advice of your
County Agricultural Agent to
determine if spraying is
necessary, advises Mr.
Johnson.
