The 1937 X 93 S prices of corn harvested for grain v/ere procured fron the 
Bureau of AgricxiLtural Economics, and v/eighted averages of the figures for the 
infested States involved in the survey were used in the preparation of the esti- 
nates. The 193^ per-hushel quotation is prelininary. Per-dozen prices of street 
corn were obtained by averaging daily quotations for the season from data supplied 
by various St^te, Federal, and city narketing agencies. In the calculations the 
following prices were utilized, 
1937 5 Corn harvested for grain, 52 cents per bushel. 
Sweet corn (per dozen ears) — Michigan, Ohio, and Indiana, 
16 cents; western Hew York, 15 cents; Connecticut, 19 
cents; New Jersey, Delaware; Maryland,- and Virginia, l4 
cents,

Sweet corn (per dozen ears) — Michigan, Ohio, and Indiana,

Virginia, 10 cents. 
Table 1 presents the estiriates compiled on corn borer damage in 1937. l932-> 
and the following discussion contains the more important conclusions to be drawn 
from the data. 
The co.'-.Tp arable infested territory surveyed in 1937 193^ composed of 
the following; 1,348,321 a,cres of corn harvested for grain, with an estimated 
crop value of -,$20 ,S29 *296 , and 33 »2S0 acres of sweet corn, with an estimated 
crop valiie of $ 4 , 096,176 in 1937 £^nd $3>733t952 in 1933. The combined acreage 
of grain and sv/eet corn v;as 1,331,501 and the estimated crop value of both was 
$24, 925.472 in 1937 $ 24 , 563*243 in 1933. The difference in value of the crop 
in 1937 ^nd 1933 was 'due to variation in the current market prices of sv/eet corn 
in these 2 years. 
The estimated total loss by the European corn borer to the above crop was 
$ 1 , 186,768 in 1937 $ 1 , 536,833 ia 1933, or an ipcreased loss of $400,065 in 
the latter over the former year. The estir.mted loss in 1933 was divided as fol- 
lov/s; Corn harvested for grain, $8l4 ,871 (51.4 percent of the entire loss), and 
sv/eet corn, $771,962 (4S,6 percent of the entire loss). In 1937 the proportions 
of total loss were 37 percent in grain corn and 63 percent in sweet corn. 
In the Lalce States area in 1933 the loss caused by the corn borer to corn 
harvested for grain was estimated at $594,495 (33»3 percent of the entire loss in 
that area), and to sv/eet corn at $ll9>l40 (l6,7 percent of the entire loss), or 
a total of $ 713 , 635 . 
In the Eastern States area in 1933 the loss caused by the corn borer to corn 
harvested for grain was estimated at $ 220,376 ( 25.2 percent of the entire loss 
in that area), and to sweet corn, at $ 652 ,, 322 (74.8 percent of the entire loss), 
or a total of $873,193. 
In other words, practically one-half of the total damage by the European corn 
borer in 1933, within the surveyed areas, occurred in sweet corn, and one-half in 
corn harvested for grain. In the Lake Sta.tes five times as much of the loss was 
in corn harvested for grain as in sweet corn, whereas in the Eastern States three-
