These losses are due to a number of species. One group = the 
rice weevil, granary weevil, Angoumois grain moth, and lesser 
grain borer = attack sound kernels. A second group = the cadelle, 
Indian-meal moth, flat and rusty grain beetles, saw-toothed grain 
beetle, dermestids, and confused and red flour beetles - may con- 
sume the germ of grains. The feeding of these insects, and also 
of flour moths and grain beetles, on broken grain and dockage may 
cause local heating in grains, with consequent formation of moisture, 
which will causs surface crusting and spoilage. 
Estimates were also made of losses of dry edible beans and peas 
due to attack by the bean weevils, cowpea weevil, and Indian-meal 
moth; of stored tobacco by the tobacco moth and cigarette beetle; 
of farmers! stock peanuts by a complex of stored-product insects; 
of dried fruits by several stored-product insects; and of fabrics 
by fabric insects. However, the losses to dried fruits and fabrics 
are not included in the tables. 
Insufficient data are at hand for estimation of losses of buck- 
wheat (a minor grain crop) or soybeans (rarely attacked by insects), 
seed crops, or shelled peanuts. No attempt has been made to estimate 
losses of dried or processed foods such as flour, cereals, corn meal, 
pepper, spices, cheese, dried milk, dry beans, or macaroni during 
processing, in trade channels, or in the hands of the consumer, 
Beans, Dry Edible 
The annual. loss in dry edible beans is estimated at 20,130,900 
pounds, Part of this loss oceurs in California due to bean 
weevils, and nart in other producing areas due to the Indiar- 
meal moth, 
Corn 
Corn losses from storage insects amounted to 51,9h7,CO0 bushels 
in 1952. Over 2 million bushels of this less was in ccrn produced 
in tha Southern States, where the rice weevil attacks corn in the 
field before harvesting and continues its depredations through 
storage. In the northern Corn Felt there is practically no loss 
in the first storage season, since the corn is harvested late in 
the fall and stored in cribs, where it rapidly ccols to outdoor 
temperatures or is artificially dried to a point where insect acti 
vity is inhibited. There was some loss in the 1951 crop carryover. 
The total estimated loss is the equivalent of one-tenth of all the 
corn procuced in Illinois, 
Fabrics 
The loss in value of fabrics containing wool due to insects is 
$350 million annually. The injury is greater on carpets, rugs, 
and wearing apparel than on blankets, upholstering, and the stored 
wool itself. The public spends $39,530,000 annually to prevent or 
control this injury to fabrics,
