THE MORE IMPORTANT RECORDS FOR APRIL, 1934 
In the Great Plains region, where the intensive grasshopper control 
campaign is being centralized, no reports of hatching of the important 
economic species were received during April. In certain limited areas 
of North Dakota where the soil is light and sandy, as high as 25 percent 
of the eggs were destroyed, apparently by drying. Other than this, con- 
ditions throughout the infested region have been favorable for grass- 
hoppers. Eggs were hatching in Montana during the last week of this 
month. In the Southwest there was a localized serious outbreak in the 
Salt River Valley of Arizona, involving about 85,000 acres, and some 
damage was observed in alfalfa and in young citrus plantings about the 
middle of April. In Idaho the two-striped grasshopper began hatching dur- 
ing the second week in April at Unmet t, Gem County; in other parts of the 
State no hatching of any of the economic species had occurred up to the 
last week in the month. Eggs of the clear-winged grasshopper were as 
numerous as 8,000 per square foot of sod in Caribou County. 
The army cutworm was appearing in numbers in wheat and alfalfa fields 
in southern Nebraska, central Montana, and the eastern, half of Colorado. 
Considerable damage was done in a number of localities. Reports of cut- 
worm injury have also been received from many points in Kansas. The pale 
western cutworm was very abundant and seriously damaging fall wheat in 
Utah. 
The chinch bug situation has not materially changed since our last 
report. Heavy flights from hibernation quarters occurred during the first 
and second weeks of April in Kansas and Missouri. 
May beetles were reported as damaging pecan buds and foliage in 
Georgia and Mississippi. Brood C adults were being found in large numbers 
near the surface of the soil in Wisconsin, and heavy flights occurred in 
Texas during the first week of the month. 
The green bug was attracting considerable attention by its depreda- 
tions on wheat and barley in southern Missouri, throughout the wheat- 
growing sections of Kansas, southwestern Nebraska, north-central Oklahoma,
