M. H. Swenk (July 15 to August l): The grasshopper outbreak 
continued to develop in extent, and somewhat in severity, during 
the last half of July. The 31 infested counties reported on 
July 15 have now increased to 65, though in many of these tho 
damago. ,is neither widespread nor serious. The infestation has 
been heavy and general, and the crop loss serious, in Arthur, 
Boyd, Buffalo, Dawson, Keith, Keya Paha, Knox, and Perkins 
Counties. Cedar, Dixon, and Holt Counties have been largely 
heavily infested. Parts of Brown, Chase, Cherry, Custer, Greeley, 
Lincoln, Rock, and Sheridan Counties have been heavily infested, 
C. J. Drake (Aujust, 3) : Grasshoppers are extremely numerous 
over a large section of Iowa, particularly in the western half 
of the State. Many fields of new alfalfa have been totally 
destroyed by the hoppers, and considerable damage is being done 
in old alfalfa fields. To illustrate, in Monona County an 
80-acre field of alfalfa was totally destroyed by the hoppers 
after the first crop was harvested. I visited this field about 
ten days ago and it was impossible to find any new growth in 
the field. The differential locust, M. differentialis Uhler, 
is the predominating species. The two-striped locust, Melanoplus 
bivittatus Say, is almost as abundant as the foregoing species. 
The rod-legged locust ,M. femur- rub rum DeG,, is also very abundant. 
The lesser migrator locust, M. mexicanus Sauss.,is almost as 
abundant as the red-legged locust. In some fields in the western 
portion of the State the hoppers run around 20 to 40 per hill of 
corn. These fields are not very numerous. Most damage is being 
done in alfalfa fields and around the margins, of cornfields. The 
State of Iowa has just purchased four carloads, of commercially 
prepared poisoned bran mash to take care of heavily infested 
waste areas along the Missouri River and other sections of west- 
ern Iowa. 
L. Haseman (August 25): During August the three common species 
of grasshoppers have been very destructive. 
H. R. Bryson (August 22): The grasshopper problem is a serious 
one over the entire State, Although there are a large number of 
all species present the greater part of the damage is being done 
by Melanoplus differentialis and M. bivittatus . M. atlanis and 
M. femur- rub rum are also numerous and will no doubt cause con- 
siderable injury this fall. Migrations from neighboring States 
have not been observed. Fall sowing of alfalfa and the seeding 
of winter wheat to avoid serious grasshopper injury promises to 
be a problem. Considerable injury was evident along the edges 
of fields of corn, kafir, and alfalfa. More reports of grass- 
hopper injury have come from the western and northeastern parts 
of the State than from other sections. 
C. Benton (July): The Carolina locust is abundant in pastures 
and fields in the southern part of the State. There has been 
much complaint of damage to tobacco as well as to clover and 
other legumes. Some injury to corn also was observed.
