OREGON FRUIT PESTS.
THE EXHIBITS OF BUGS, INSECTS, ETC.,
AT THE EXPOSITION.

AT THE EXPOSITION.
Oregonian, Oct. l3: Among the visitors
at the Exposition hall yesterday was
Professor Frederick L. Washburn, entomoI.
ogist of the Agricultural College, near Cor
Wallis. The general and wide spread inter-
est which is being taken throughout the
state in the work of the N. P 1. A., and
which. it is to be hoped, will increase in
geometrical ratio as the years go by, is
further evidenced by the fact that the
professor brought with him a case in which
are ranged in classes number of the many
varieties of the Oregon insects, which the
patient and educated seeker for knowledge
finds, after search, in the grasses, on the
tres, and among the vegetable and flower
gardens of the state.
Professor Washburn comes at the instance
of the board of regents, who desire to lend
in this way helping hand in the work of
putting the farmer and orchardist on their
guard in the matter of the destruction of in.
furious and the preservation of beneficial
insects The different insects and bugs in
the Ease referred to are distinctly labeled.
Every farmer and fruit raiser and garden
er and flower grower who visits the Exposi-
tion will consult his own interest by examin.
ing the collection. And to enable him to do
as much as possible to his own advant-
age, he will do we'll to cut out the follow
ing ''few remarks and ''paste them in his
hat," or keep them elsewhere, where they
will be convenient for ''ready reference"
Among the injurious insects the Goblin
moth, the peach borer, the cutworm moth
and the cherry slug. A careful inspection.
of the specimens in the case and study of
their ''birth marks" will enable anyone to
recognize his enemy at sight, and take the
most approved methods for his extermin-
alton. The bugs shown, for the most part,
are injurious. Among the beetles shown,
except the Plain Lady Bird &c. n1unda) the
Ground beetle (harpulus) and the Tiger
beetle, are also, for the most part, in
furious. The work of the first mentioned
the Lady bug, is to destroy the aphids,
which they do by eating some themselves
and depositing their eggs among the re-
mainder, leaving their progeny and their
SUCCESSORS to continue the good work ad-
intinitum; the second-class, the Ground
beetles and their Larvae. consume many des-
5ructive insects; the third, the Tiger beetles,
perform about the same functions as their
cousin germans, the ground beetle. Amoung
the beneficial insects shown are also the
Syrphus fly, the lchneumon fly and the Lace
Wing fly. The first destroys plant lice, the
second injurious caterpillars, the third the
woody louise of the apple tree aud other plant
lice.
This depal tment of the Agricultural Col
lege is cooperating heartily with the State
Board of Horticulture, each working in their
respective spheres of action, each capabable
of conferring incalculable benefits upon tho
state, and each deserving of the moral and
material aid of the citizens of the common
wealth. 1t is not out of place again to ex-
press the qualification which all ought to
feel in view of the evidences of practical
work shown by the regents and faculty of
the State Agricultural Society at the great
Exposition OF 1890.
The people have right to expect practical
results from this literally endowed state in
sttution, and the faculty thereof cannot de-
wise better plan to make what they do in
the lines along which their work runs. known
and seen of all men, than to spread them
out before the gaze of the public at great
gatherings of the people at expositiOns
and state and county fairs. What has been
done by them this year is good and crdita-
BILE. Next year, no doubt, they will make
their interesting and instructive "object les
sons" distinctive feature of the great Ex-
position.
