6 MONTANA EXPERIMENT STATION BULLETIN 216 



measures are recommended to the owner, who puts them into 

 operation at his own expense. If control operations on a large 

 scale are needed or if dangerous insects are breeding on public 

 lands and thereby becoming a menace to crops on privately 

 owned land, the county authorities are appealed to and the 

 county pest law is used. In the latter case the State Entomolo- 

 gist or his assistant spends considerable time in the county, 

 selecting and training the local men who are to be left in charge 

 and outlining a control campaign. After the county organiza- 

 tion begins to function successfully the State Entomologist is 

 free to give aid in some other section of the state, returning 

 frequently enough to make sure that the local organization is 

 operating successfully. 



In addition to field work in connection with insect out- 

 breaks, surveys must be conducted to determine whether un- 

 usually dangerous insects like the European corn borer and 

 the alfalfa weevil are already within the state. To wait until 

 their presence is indicated by damage to crops would be dis- 

 astrous, for the insect would have such a start that it would 

 be very difficult to prevent it from spreading to all parts of 

 the state. 



>VHO DOES THE WOKK 



The Entomologist of the Experiment Station is by law the 

 State Entomologist; he also gives half of his time to teaching 

 entomology in the Montana State College. Since he receives no 

 salary from the State Entomologist fund his first duty is to 

 the Experiment Station and to the College, each of which pays 

 half his salary. It is obvious that the State Entomologist could 

 not satisfactorily perform his duties in the Experiment Station, 

 teach classes in the State College, and have much time left to 

 travel about the state demonstrating insect control. The actual 

 field work is therefore carried on to a large extent by an as- 

 sistant working under the supervision of the State Entomologist. 

 The present Assistant State Entomologist is W. B. Mabee, a 

 graduate of Montana State College and for several years Exten- 

 sion Entomologist in North Carolina. He is employed on a 

 ]!art-time basis, giving half of his time to the Experiment Sta- 

 tion and half to the work of the State Entomologist's office.
