GENERAL FEEDERS 
GRASSHOPPERS (Acrididae) 
General* W. E. Dove (May 26): In the Red River Valley areas of' Minnesota and 
North Dakota, in eastern Montana and Wyoming, and in western North Dakota, 
South Dakota, and Nebraska, hatch of migratory grasshopper Melanoplus mexi- 
canus Sauss. and two-striped grasshopper M, bivittatus Say' 'is almost complete, 
while hatching of the big yellow grasshopper M. different ialis Thos. is just 
beginning. Rapid hatch and acceleration of development of young hoppers 
caused by warm, dry weather. Rapid movement from adjacent, idle and range 
lands into cropped areas temporarily reduced by rains occurred during the 
week. Although average percentage of damage to crops in the northern Great 
Plains area remains small, some fields have been completely destroyed in 
parts of Wyoming, eastern Montana, and the western part of North Dakota, 
South Dakota, and Nebraska. Heaviest damage where grasshoppers hatched in 
fields in which the grain had been stubblod in. Hatching of migratory range 
grasshopper in the Texas Panhandle, Oklahoma, northeastern New Mexico, and 
eastern Colorado practically complete in some areas and less advanced in 
other areas of higher altitudes, A very small hatch occurred in the Missis- 
sippi Valley during the last week. 
Michigan, R, Hutson (May 24): M, mexicanus seen throughout the Lower Peninsula. 
Second-stage nymphs observed in s everal ‘ places as far north as Roscommon, 
Camnula pellucida Scudd. observed hatching at Roscommon and in the south- 
eastern counties. Ageneotettix deorum Scudd. is in the same stage of devel- 
opment in the same area as M. mexicanus * 
Wisconsin, E. L. Chambers (May 2?): M. mexicanus began hatching in the light- 
sand areas in the vicinity of Juneau County, central Wisconsin, on May 10, 
and control activities are being carried on’in that county. Last spring 
hatching began about April 15« 
Minnesota. A. G. Buggies and assistants (May 20): Main hatch of M. mexicanus 
amounts to 8 percent in some spots and 100 percent in the Red River Valley, 
First hatch recorded on April 27. M. bivittatus second to M. mexicanus . 
Very few C. pellucida hatched to date. Hatching reported as started in 
Chisago, Otter Tail, Bennington, and St. Louis Counties. 
Iowa, C. J. Drake (May 26): M. bivittatus and M. mexicanus hatching in large 
numbers, particularly along the Missouri Valley. Control operations in 
progress for 2 weeks, particularly near the larger cities. Semi-drought con- 
ditions favorable for young grasshoppers during the hatching period, 
Missouri, L. Haseman (May 24); Hatch in the north-central part of Missouri de- 
layed by the weather, and until the middle of May very little hatching had 
occurred in the northern tier of counties. Heavy hatch in places reported 
from southern Missouri 2 weeks earlier, 
G. D, Jones (May 10): North-central Missouri is the area most heavily 
infested with eggs, according to the survey of last fall, which indicated 
that more than normal egg populations exist in every district where grass- 
hoppers were abundant last year. Eggs held back in development owing to cool
