A BULLETIN 



ON 



DESTKUGTIVE GRASSHOPPERS OF KANSAS. 



Grasshoppers as pests are well known in Kansas. Here the 

 effects of their ravages have been fully demonstrated. While such a 

 general devastation as took place in the '70s may never occur again, 

 local destruction of crops is sure to take place at times unless well- 

 directed means of ijrevention are used. 



Since all grasshoppers (or locusts) subsist upon vegetation, all are 

 injurious. Some species, however, possess peculiar characteristics 

 or are favored by special conditions, making their numbers greater; 

 consequently the damage is more noticeable. Of this class the pres- 

 ent paper will treat. 



From various localities in the state the department has received 

 complaints concerning destruction by grasshoppers. A letter from 

 Mr. Geo. W. Watson, Kinsley, Kan., was referred to us by the secre- 

 tary of the State Board of Agriculture. After considerable corre- 

 spondence with Mr. Watson, we thought it advisable to visit that 

 locality and take observations upon existing conditions. Accordingly 

 the junior member of the department left for Edwards county on 

 September 29. The department is greatly indebted to Hon. Jno. E. 

 Frost, land commissioner of the Atchison, Topeka & Santa Fe rail- 

 way, for favors of transportation upon this and other trips for similar 

 purposes. 



On the morning of the 30th, Mr. R. E. Edwards, president of the 

 Kinsley Bank, took us to a large tract of alfalfa southwest of Kinsley. 

 There are about 400 acres of alfalfa in this piece, all the property of 

 Mr. Edwards. Here we found a few of the Rocky Mountain Locust, 

 but many more of what is known as the Dift■erentici^ Locust,, or 2J[cl--
