Insecticides Show Promise In War On Pests
OREGON STATE COLLEGE
Entomologists waging the war
against forest insects are adding
a new and highly promising wea
pon that of systemic insecticides.
The insecticides get that name
because they are absorbed into
and circulated throughout the
tree's entire system, an Oregon
State College scientist explains.
This means that gnawing or suck
ing pests that eat into the bark or
leaves will get a lethal dose of the
insecticide as part of their meal.
Gnat Potential
Much research still needs to be
done on systemics for foresty use,
Dr. Julius A. Rudinsky emphasiz
es, but they show great potential
for selective and extended control
of some insects that have largely
defied control before.
They may be especially useful,
for example, against such insects
as bark beetles, miles, and aphids
that have been able to "hide '
from other chemicals, he believes.
Insects are the forest's worst
enemy, killing five or six times
as much timber each year as lost
to forest fires.
Special Advantages
Systemics will not replace other
conventional insecticides, Rudinsky
tcction of seedlings during their
first season; trunk and root appli
cations for younger and mature
trees; complete treatment of trees
with limited spray coverage; and
"selective control" possibly of par
ticular pests without killing off oth
er beneficial insects as well.
Application Methods . .
Protection from systemics may
be achieved at surprisingly low
rates of application, research
shows, and lasts for an extended
period. Application may be made
either by painting the insecticide
in a band around the trunk, by
needle injection, foliage spray, or
soil application.
Small plot studies in this country
and Europe are encouraging, Ru
dinsky said, but additional studies
are needed before practical meth
ods of large-scale systemic appli
cation under forest conditions can
be developed.
Future research will -include
work on time of application, mode
of absorption by the tree, detoxifi
cation or "wear out" of the tree
compounds less toxic to warm
blooded animals and to fish.
Forest Losses
Few people realize the tremen
dous forest losses inflicted each
noted, but do have some special j year by insects, Rudinsky report
important advantages. ed. Last year in the United States,
These include seed treatment: forest insects killed enough timber
and soil applications for the pro-'to build 600,000 five-room houses
and ' killed one-fourth as much
pulpwood as consumed in the man
ufacture of the nation's newsprint.
Added losses were caused bv
forest infestations which did not
kill trees outright, but slowed
growth and deformed trees. Ore
gon, the nation s number one for
estry state, is among the hardest
nit. J lie recent bark beetle epi
demic saw some 6,000,000 acres of
Douglas fir forests infested. And
from 1931 to 1942, the western pine
stands to the extent of 6,000,000,000
board feet.
Contra! Complicated
Control of forest insects is com
plicated by several things, Rudin
sky explained. One is that the
Northwest's great, continuous
stands of the same kind of trees
are highly susceptible to spread of
an insect over a huge area.
Chemical control programs that
have worked wonders on farm
crops including the use of sys
temics are vastly more complex
on torests Because ot tne tree size
and the great areas involved.
Predators, or insects that prev
on the damaging pests, are being
tried with some success. Careful
and proper management of forest
stands also can help check losses,
Rudinsky stated.
The svstemics represent a pow
erful new control approach that
will be increasingly important in
coming years, he concluded.
