MONTANA EXPERIMENT STATION BULLETIN 238 



CORRESPONDENCE ON INSECT PESTS 



Following is a tabulation of tlie subjects of correspondence dur- 

 ing 1929 and 1930, -with the names of the insects, localities, and dates. 

 Each entry in this table called for at least one letter, and in many 

 instances for extended studies and rearing or breeding of the insect 

 sent. Each correspondent was advised of the best known sprays or 

 methods of control. This list of insect pests giving trouble in Montana 

 is far from complete because many of the inquiries go directly to the 

 county agricultural agents. For the information of county agents 

 this office supplies them with mimeographed sheets dealing with many 

 of the leading insect pests.
