CORRESPONDENCE ON INSECT PESTS 



The i'ollowing tabulation of the insect i)est correspondence for 

 ] 931-32 is made up of inquiries whicli came to the state entomologist's 

 office and represents only a small part of the entire correspondence 

 in Ihe state on tliis subject, for nnich of it was handled directly by 

 the county agricultural agents. The list as printed here is a fair 

 sample of the many destructive insects against which farmers have 

 1o defend their crops. This list of insects is printed not with the 

 idea of showing the volume of correspondence which is liandled but 

 rather Toward fulfilling the need for information as to the seasonal 

 distribution of injurious insects over the state, a complete record 

 (if which for a scri(^s of years is of great value in studying the rise 

 and fall of iiiscd |)0|)ubit ions as correlated with weather conditions.
