GENERAL FEEDERS 
GRASSHOPPERS (Acrididae) 
Michigan, Ray Rut son (July 22): Grasshoppers are very abundant in the upper 
peninsula and the northern part of the lower peninsula. 
Wisconsin. E. L. Chambers (July 24): Very serious damage has occurred in about 
30 counties of northern Wisconsin, principally the northeastern third. Near- 
ly 100 tons of white arsenic was used in baits in addition to several car- 
loads of molasses and many carloads of bran. 
Minnesota. A. G. Rugbies (July 15); . We are controlling grasshoppers remarkably 
well in spite of ideal weather for the hoppers. The prediction made last 
December, was 99 per cent correct. 
North Dakota. J. A. Munro (July 22): Reports indicate that various species of 
grasshoppers are very abundant over most of the area previously reported as 
infested. Where control was begun early, successful poisoning campaigns 
have resulted. Eggs are now being deposited by Melanoplus bivittatus Say, 
H. mexicanus Sauss,, and C amnula p ellucida Scudd. 
R. L. Olson (July 17); Strong grasshopper flights high in the air were^ 
.mot'ecV on July 9, in Bowman County, all going southeastward. 
Mississippi. C. Lyle (July 21): Several scattered outbreaks of grasshoppers, 
chiefly M^ diff erentialis Ihos., in the Mississippi Delta were reported dur- 
ing the past month. Serious damage, continued on several thousand acres of 
corn, soybeans, and cotton at Parchman until the application of several car- 
loads of poisoned bait gave control. 
Nebraska. R. Roberts (July 20): Grasshoppers have been very abundant in the 
northeastern part of the State. A state-aided control campaign has been 
in progress for over a month, 18 carloa.ds of poisoned bran mash have been 
distributed, and good kills have been reported.: Reports have also been 
received from Douglas, Saline, and Harlan Counties. 
Wyoming. C. L. Corkins (July 21): Grasshoppers are very abundant. A severe 
outbreak developed during earl;- July in Crook County. The valleys are 
infested with M^ bivittatus , and the grazing lands in the hills have a 
mixed infestation of any species, which are now migrating to the valleys. 
Certain sections of Sheridan County have serious troubles. Minor outbreaks 
have developed in Fremont, Johnson, and Weston Counties. 
Utah. G. F. Knowlton (July 11): M^ bivittatus is damaging sugar beets, straw- 
berry plants, and black-cap raspberries at Hoop. r. Grasshoppers are damaging 
alfalfa and grain on the ranches in Skull Valley, particularly at Icscpa. 
Large numbers of M^ mexicanus are becoming adult in man*'- parts of Tooele 
County and are causing serious damage to crops at Grantsville. (July 21): 
Grasshoppers completely destroyed a 3-acre sugar-beet patch, then advanced 
upon wheat and barley during June, in the low area west of Provo. 
California. A. E. Michelbacher (July 20): In at least one area near Tracy the 
differential grasshopper, M. diff erentialis , is rather abundant. I have
