ENTOMOLOGY 8ERV1CP] IX .MONTANA 



The organization of services in entomology in the State of ^ion- 

 tana has grown up during the past thirty-two years. The natural 

 divisions of such services in any State are four in number : 



1. Instruction, or tiie organized teaching of college classes in 

 entomology. It can scarcely he said that there is any teaching of 

 entomology in the high schools or graded schools. 



2. Investigation, or tlie study of the insect problems of the 

 region. These studies may be very special and worthy of the term 

 "research" or they ma}' be general and directly practical. The 

 agricultural experiment stations carry on most of the investigations 

 of insects done by the States. 



3. Extension, or the taking of the results of investigation or re- 

 search to the farmer and tax-payer in an effort to save crops, relieve 

 domestic animals of parasites, destroy granary or household pests, or 

 to destroy any insects that become injurious. 



4. Regulatory service, or the enforcing of such laws on inspec- 

 tion or quarantine as the State has found it necessary to enact. 



There is yet another class of service which has to do with the 

 solving of special problems which often are large and of much im- 

 portance, and involve the expenditure of considerable sums of mon<\v. 

 States pass laws on these problems, appropriate monej' and set up 

 special organizations to care for them. Many States have such special 

 problems. In ]Montana the problem of the woodtick is an excellent 

 example and the State in the year 1913 set up the State Board of 

 Entomology to care for it. 



In Montana the first three of the above headings quite naturally 

 fall to the State College and Experiment Station. The fourth one 

 has been assigned to the State Department of Agriculture Avhere it 

 naturally belongs. 



Insect pest problems often come up as emergencies. Grasshoppers, 

 cutworms, or other insects suddenly increase to alarming numbers 

 and would do damage amounting to millions of dollars if not promptly
