GRASSHOPPERS 
Although the grasshopper situation was much less alarming in the fall cf 
1932 than it was in the fall of 1931, the weather was extremely favorable dur- 
ing the hatching season and winter and spring mortality was extremely lew in 
the Great Plains, the egg survival running from 90 to 95 percent over most of 
the territory. Heavy infestations occurred along the northern half of Montana 
east of the Rocky Mountains into the western half of North Dakota and across 
South Dakota in a hand extending from the northwest to the southeast. A large 
area of heavy infestation occurred in north-central Wyoming and in the north- 
eastern corner of that State, with an area of lesser infestation along the 
foothills of the Rocky Mountains. Eeyond these areas moderate infestations 
occurred over the greater part of Montana, the northern two thirds of Wyoming, 
the southeastern corner of Idaho, and in northern Utah, the remainder of North 
and South Dakota, and along the northern border of Nebraska. In Minnesota, 
moderate infestation occurred in the northwestern part of the State, with more 
intense infestation in the northeastern and central parts. Somewhat severe 
damage was also recorded from the northeastern half of Wisconsin, practically 
the entire northern peninsula of Michigan, and the nortnrestem corner of the 
lower peninsula. Control campaigns were put on in several States as far as 
the extremely depleted finances of the farmers would allow. Scattered out- 
breaks were reported in Iowa, Oklahoma, Mississippi, Texas, Colorado, and 
Nevada. Populations continued heavy throughout the remainder of the summer, 
and there was considerable migration. The dominant species in the most 
heavily infested territory was the lesser migratory grasshopper, Melanoplus 
mexicanu s Sauss. Dall egg surveys in northern plains indicate a very serious 
situation. The fall survey of this area for 1932 showed only 2 counties 
(in southwest North Dakota) which had egg populations sufficiently heavy to 
threaten from 50 to 100 percent of the crops this year in this entire terri- 
tory; this year 35 counties are as heavily irfested as this. Infestations 
running over 25 percent were found in 24 counties in the fall of 1932 and in 
93 counties this fall. The most notable increase in seriously infested 
territory is across northern Montana and in north-central and northeastern 
Wyoming. This year comparatively heavy infestations are also reported from 
southeastern Idaho and northeastern Minnesota, with a very heavy infestation 
in northern and southwestern North Dakota and in centa'al South Dakota. 
Similar heavy infestations extend well northward into Alberta, Saskatchewan, 
and Manitoba in Canada. 
CHINCH PJG 
The chinch bu^ ( Bli ssus leucopterus Say) overwintered successfully over 
the greater p^rt of its normal habitat and also somewhat north of this region. 
Heavy rains late in April and early in May materially checked its development 
in many sections, particularly in the eastern part of the territory. Late in 
May and in June heavy populations built up in northern Missouri, central 
Illinois, northern Indiana, and west-central Ohio. During July and August 
severe depredations occurred from northern Missouri eastward to Ohio, with 
less important outbreaks extending from east-centrrl Texas, across central 
Oklahoma and eastern Kansas, to southeastern Nebraska, thence eastward across 
southern Iowa to southern Michigan. In the fall generally heavy populations 
were reported throughout this entire territory; and an isolated heavy infes- 
tation occurred in ten counties in Pennsylvania extending from Adams County
