GRASSHOPPERS IN GENERAL. 



TN the minds of some there exists an opinion that among states 

 Kansas alone has suffered most, is most subject to injury from 

 grasshoppers, that these grasshoppers are migratory, that there is no 

 means of checking them hence, they are a necessary evil, and the 

 less said about them the better. 



For the benefit of such, as well as for general information, it may 

 be well to give the situation as it is. Since the Rocky Mountain Lo- 

 cust is the most renowned, we have, placed in brief form, as taken 

 from Riley, Bruner, Packard, and others, the data following, showing 

 number of annual visitations the Rocky Mountain Locust has made, 

 and the states which these locusts visited. These insects doubt- 

 less occurred frequently prior to dates given, but no records were 

 retained, since these regions were at that time uninhabited by record- 

 keeping people. The record from 1866 is full; the completeness of 

 the record from 1866 is due, not necessarily to greater prevalence of 

 the locust, but to better facilities for securing such data. 



I have placed after each state here named the number of annual 

 appearances of the Rocky Mountain Locust within the twenty-eight 

 years between 1851 and 1878. Before 1851 we have no authentic 

 records, and since 1878 this locust has committed little damage in this 

 state. For this reason this period has been chosen. 



Number of annual visitations of the Rocky Mountain Locust to 

 states named, during the period 1851-1878 : 



Arkansas, 2. Kansas, 14. New Mexico, 3. 



British N. America, 10. Minnesota, 18. Texas, 15. 



Colorado, 12. Missouri, 8. Utah, 26. 



Dakota, 17. Montana, 18. Washington, \ , 



Idaho, 5. Nebraska, 13. Oregon, \ ' 



Indian Territory, 5. Nevada, 4. Wyoming, 10. 

 Iowa, 15. 



While Kansas has been free from the attacks of these insects since 

 1878, it has not been so with some of the other states named, notably 

 Minnesota, where, in 1891, the crops of several counties were com- 

 pletely taken by this locust. From a glance at the list, it can be seen 

 that, up to 1878, seven states had a greater number of visitations from 

 this locust than Kansas. Further, it may be well to note that there 

 were only three seasons in Kansas when this grasshopper's damages
