December 1, 1918. 
To His Excellency J. A. A. Burnquist, 
Governor of the State of Minnesota. 
Dear Sir: 
In compliance with the Revised Laws of Minnesota 1905, Chapter 
38, Section 2382, I have the honor to present herewith a report of the 
State Entomologist for the year ending December 1, 1918. 
A typewritten report for the year ending December 1, 1917, cover- 
ing the year’s work in nursery inspection and other duties of the State 
Entomologist was sent you in December, 1917, by Professor Washburn 
and a published report of the work on the White Pine Blister Rust by 
Mr. Washburn took the activities of the State Entomologist practically 
up to February, 1918. At that time the writer assumed the duties of 
this office, Professor Washburn having resigned the office of State 
Entomologist to continue his work in the university as zoologist of the 
Experiment Station. 
As the insect work of the year 1918 had not begun, plans for 
the growing season were developed immediately. There were two main 
phases of the work to be kept in mind; one the purely mechanical work 
of inspection, and the other the carrying on of plant pest campaigns. 
Besides these two main functions, experimental insect control problems 
had to be conducted in connection with the Experiment Station work. 
The policy adopted was that the two main functions mentioned should 
be carried on at the same time; that the nursery inspection work 
should be closely merged with the educational or extension work and 
that the inspectors would then be looked upon not as policemen but as 
associates and helpers. The policy was to work in every possible way 
to keep plant pests out of the state, but if any should become established, 
to find the best method of controlling them and assist the nurseryman, 
orchardist, gardener and others in their control. 
This policy was followed very closely during the last season and 
has produced excellent results. 
As the chapter of the Minnesota law previously quoted makes the 
State Entomologist responsible for combating insect pests and plant 
diseases, the work this year naturally divided into four groups: 
1. The inspection of nurseries ; 
2. The control of white pine blister rust; 
3. The eradication of the common barberry ; 
4. The study of life histories and control measures for insect 
pests.
