COM EAR WORM 
The corn ear worm (H elioth is ob sol eta Fab.) was much more abundant than 
usual throughout the South. At points in the Sulf region 80 percent of the 
winter corn was rejected at the packing shed on account of infestations and 
100 percent infestation was quite general. Throughout the Middle Atlantic, 
East Central, and West Central States infestations were about normal, while in 
Hew England and the North Central States damage was decidedly less prevalent 
than was the case last year. In the South, in addition to attacking sweet 
corn, the larvae seriously infested tomato. In North Carolina they did some 
damage by burrowing into half-grown peaches; this was usually a consequence of 
cutting vetch in the peach orchards. 
ARMYWORM 
The first adult armyworm ( Cirphis u nipuncta Haw.) of the season to be 
recorded was taken in a light trap at Clemson College, S. C, March 1$. During 
the first week of April heavy flights of moths occurred in central Illinois. 
Late in May the first outbreaks of the season were reported from St. Marys 
County, Md. , and James City County, Va. Late in May and throughout June out- 
breaks were reported from West Virginia, Pennsylvania, Tennessee, Wisconsin, 
and North Dakota. 
CUTWORMS 
During the last week in March considerable damage was done to wheat in 
Kansas and Oklahoma by the army cutworm ( Chorizagrotis auxiliaris G-rote). 
This cutworm also damaged fall- sown alfalfa, oats, and vetch. The popula- 
tion at Manhattan averaged 45 cutworms per square foot, with a maximum record 
of 90. This species was found in wheat fields in Cascade County, Mont. 
After the spring advanced the usual reports of cutworm injury were received 
from practically the entire country. During May the army cutworm was again 
reported damaging small grain in South Dakota; and in early June, flights of
