THE MORE IMPORTANT RECORDS FOR MAY, 1932 
During the first week in May grasshoppers "began hatching quite general- 
ly in northern Utah, and were starting to hatch in South Dakota and Nebraska. 
During the second week in the month (May 13) they were first observed hatch- 
ing in Minnesota, North Dakota, and Iowa, and second-instar nymphs were 
observed in the field in Missouri. By the 3rd week of the month they were 
so abundant in southwestern Oklahoma and over a wide territory in Texas as 
to require remedial measures and the farmers were starting to use poisoned 
bran. The situation is reported as serious in the Great Plains region and 
in scattered localities southward to Texas. 
The cutworm situation reported in the last number of the Insect Pest 
Survey Bulletin has not materially changed. Reports of occurrence have 
been received from the greater part of the country. 
The Hessian fly infestation appears to be heavier and more general 
throughout the winter wheat belt than it lias been in several years. 
The chinch bug situation has not materially changed. Despite the cold 
rains in early May, these insects are still present in threatening numbers 
in southern Illinois and central Missouri. 
The green bug developed to destructive numbers in west-central Missouri 
and northwestern Mississippi. A small outbreak was also reported in south- 
central Pennsylvania. 
The corn ear worm put in its appearance during the month in the southern 
half of Mississippi; by the third week in the month there was a heavy infes- 
tation on tomatoes in the Gulf Coast district of Texas. 
Reports of heavy infestations of alfalfa by the pea aphid have been 
received from Pennsylvania, South Carolina, Ohio, and Mississippi. The 
numbers of these insects were decidedly below normal this month in Wisconsin 
and Oregon. 
By the first of the month an. unprecedented flight of moths of the 
alfalfa webworm ( Loxostege commixtalis Walk. ) occurred in Colorado and 
-127-
