GRASSHOPPERS (Acrididae) 
i 
Indiana. J. J. Davis (July 28): On June 21 • grasshoppers ( Melanoplus 
bivittatus Say) were first reported as abundant in Vanderburg County, 
where they were attacking corn and soybeans. A personal inspection 
on July 10 revealed an abundance of hoppers - but as yet there is no 
serious damage, partly because of the excellent growth of the plants. 
The area infested is overflow ground. 
Wisconsin. K. F. Wilson (June 30) : We have had the worst outbreak of 
grasshoppers ever known to occur in Wisconsin. The infestation ox- 
tends from west to oast through the northern part of the Statu. 
S. L. Chambers (July 30): Active poisoning is being continued in 
the extreme northern counties where the grain is being cut and the 
grasshoppers are migrating into com and potatoes from hay and small- 
grain fields. Egg laying is taking place throughout the entire area. 
In most of the heavily infested counties l^rge numbers of grasshoppers 
are being killed by thread worms and fungous diseases following sever- 
al days of wet weather, 
Minnesota. A. G. Ruggles (July 28): Grasshoppers are very .abundant. 
North Dakota. J. A. Munro (July 18): Crop destraction by grasshoppers 
has been held at a low figure, although spring infestation indicated 
almost complete destruction in many areas. 
South Dakota. H. C. Severin (July 5) ' Grasshoppers are not nearly so 
abundant as wo had every' reason to believe they would be. This is 
probably due to the drought', which last fall, winter, and spri- 
dried out .and destroyed' large numbers of eggs and which undoubtedly 
cut down the food supply so that there was not sufficient food of 
the proper type to keep some species; to the blowing of soil, which 
covered up immense numbers of eggs, especially along fences and road- 
sides; to heavy rains in some localities; and finally to the effective 
poisoning campaign being conducted in the State. 
A. L. Ford (July 17): There are four distinct areas of heavy in- 
festation, the largest of which is in the southeaster., part of the 
State, extending along the Missouri River northward to Jerauld County 
and westward to Grogory. A smaller area along the western border of 
the State from Lawrence to Custer Counties; two smaller areas, one 
centering in Sully County and- extending into Potter and Hughes and 
southeastern Armstrong and Dewey Counties, the other in northern 
Haakon and southern Ziebach Countie?.M. bivittatus and M. mexicr.nu s 
predominate throughout the State, being present in all sections. In 
the area which includes parts of Lawrence, Pennington, and Custer 
Counties there is a serious outbreak of the warrior grasshopper, 
C. p sllucida . M. femur- rub ru n DcG, is fairly ahundant throughout 
the eastern half of the State, especially in alfalfa, but this species
