THIRTIETH REPORT OF THE STATE ENTOMOLOGIST 



13 



county officials, and the Indian Service and Forest Service. In 

 other communities, roadsides and some idle land were baited by 

 paid Bureau crews but farmer participation was not so extensive. 



The results of this program will not be completely understood 

 until the spring of 1945 but an extensive egg survey seems to in- 

 dicate that the threatening population in Camas Prairie has been 

 reduced to noneconomic status. Where farmer participation was 

 not extensive the program was only partially successful and 

 threatening populations still exist in the Hot Springs and Lone- 

 pine communities. Because of the small area involved and the 

 different cropping system used in the Plains community little can 

 be concluded as to results of the campaign in this community. 



While much more needs to be done in all parts of the State 

 and with different grasshopper population complexes, there seems 

 to be some support for fall baiting campaigns to reduce incipient 

 grasshopper outbreaks. Where marginal concentrations exist, bait- 

 ing of all field margins, roadsides, railroad rights-of-way, etc. may 

 be sufficient. Where concentrations are in fields and areas not 

 accessible to machinery travelling public thoroughfares, extensive 

 baiting of fields, idle land, range, etc. must be carried on. 



GRASSHOPPER OUTLOOK FOR 1945 



The grasshopper outlook for 1945, based upon 1944 adult and 

 egg surveys, is that the area of infestation will approximate that 

 of 1944 but will increase in intensity. (Figure 3). Eastern
