DEPREDATlONS
CHRONOLOGICAL DEPARTMENT
OF THE COLORADO AGRi.
CULTURAL COLLEGE.
RESULTS OF ITS WORK
CONTROLS INSPECTION OF ORCH.
ARDS AND NURSERY STOCK
OF THE STATE.

The chief work of the entomologists
Of the Colorado Agricultural College
pnd Experiment Station is the study
CT insect pests injurious to orchards,
gardens, field crops and farm animals
rid OF practical methods of controlling
them and of reducing the enormous
losses which they cause
Prof. L. P. Gillette is at the head of
this work and is assisted by three men
and one woman. The building cost
$4,000. the apparatus, collections and
supplies are valued at $13,O37, and it
cost $16,564 to operate the department
for the two years ending November
30, 1905
Professor Gillette has been with the
college eighteen years. His first work
Of combating the codllng moth, an in
EJECT that if left alone would destroy at
least three-fourths of the entire apple
crop of the state. He and his assist

this insect up to the present time.
Special effort has been made to re-
CT ce the cost necessary to combat the
codling moth and to increase the eff
| cheney of spraying. The work of the
entomologist and chemist of the Colo.
RADIO Agricultural College will enable
Colorado fruit growers to save this
year 100000 in controlling this pest
and at the same the secure better
results
The next most serious orchard pest
is plant lice and the department has
developed practical methods OF com
| batting this enemy and has secured
general adoption of these methods by
the fruit growers of the state
A prominent Canon City fruit grow
er stated that the advice given by
Professor Gillette had been worth to
the fruit growers of Canon City alone
100000. Other fruit growers agreed
with him and the work has been pro-
ptrtionately valuable to the orchard
men of the Western slope.
Thirty-four bulletins on insects have
been issued treating of insects injuri-
Gus to orchards, gardens, field crops
and animals; also of bee-keeping. The
dip perfected by this department to
cure sheep scab is in general use
throughout the world and is known as
the Fort Collins dip.
Classes are taught in entomology,
zoology. histology, animal parasites
end human physiology, and the enroll
Elent in all classes for the year ending
March l. 1909, was 294.
Four students from this department
are heads of departments in other ag-
ricultural institutions and five are in
tfe chronological work of the govern
nent. All are making good"
There are 10000 specimens in the
Economic museum, the most complete
collection of Colorado fauna. and the
collection is in constant use for refer
ence in solving practical problems.
Professor Gillette is state entomol-
ogist and has control of the work of
inspection of the orchards and nursery
stock Of the state and of all nursery
stock shipped in. This inspection is
to prevent the Introduction and spread
Ct insects and plant diseases.
Investigation is being continued on
the codling moth and the plant lice
Investigations are also in progress to
determine practical methods of com
batting the flea beetle and the plant
lice affecting sugar beets. The flea
beetle causes an average annual loss
of half million dollars to the pota-
tees Of the state and the plant lice
causes reduction In the sugar CON
.rnts and large reduction in the
yield per acre of the sugar beet.
