THE OUTLOOK FOR GRASScHOPPERS IN 1933 

 No heavy infestations of grasshoppers are expected during 1933 

 but a number of sections can anticipate some trouble from slight 

 to moderate numbers of these pests. This is the prediction based 

 upon a survey made by the Montana Agricultural l^xperiment Sta- 

 tion in cooperation with the United States Bureau of Entomology. 



Figure 3. — Areas in Montana where grasshopper infestations are 

 expected to occur in 1933. The dotted part shows the counties 

 covered by the survey. The black areas are where moderate 

 outbreaks are expected and the oblique-lined portions show where 

 only slight trouble may occur. 



In general grasshoppers will occur in 1933 in very much the 

 same territory as in 1932. (See Figure 3 as compared with Figure 2.). 

 It is likely that there will be fewer 'hoppers in Lake and Flathead 

 counties on account of the effective control work done there the 

 past summer. On the other hand, evidence has been obtained to 

 show that the Centennial Valley in Beaverhead County must pre- 

 pare for a very much increased abundance of grasshoppers.
