Minn. Effect of the Association of Molds and Insects on the 
Keeping Quality of Stored Grain. To learn if the development of 
insects within stored grain bulks is associated with, or contri- 
butes to, growth of storage molds that are known to lead to heat- 
ing and other spoilage of stored grains.

Miss. Control of Insect Pests of Stored Corn and Small Grain. To 
learn (1) necessary modifications of steel and other type bins 
used in Mississippi for the efficient use of fumigants; (2) rates 
and frequency of application of fumigants needed in properly pre- 
pared bins necessary to avoid being graded as 'weevily'; (3) 
efficiency of ‘grain protectants’ for the control of different 
species of insects on clean grain; (4) effect of foreign matter 
and moisture content of grain (surface and beneath surface) on 
the control obtained from use of ‘grain protectants’ and fumi- 
gants; (5) importance of field infestations and possibly of farm 
management being used to reduce the infestations; (6) value of 
chemicals other than those tested which have characteristics that 
suggest a possible means of control of the rice weevil on corn 
stored in the shuck; and (7) differences in the rate of increase 
of rice weevil populations in those corn single crosses which have 
possibilities of being used for the production of hybrid seed.

N. Ce. The Control of Insects Affecting Stored Grain. To learn (a) 
changes in grain grade and other measures of quality with respect 
to levels of population of storage insects; (2) resistance of 
certain varieties to storage insect attack and causes responsible 
for resistance; (3) relationship between moth and weevil develop- 
ment in stored grain as affected by time of planting and harvest; 
(4) best fumigants and other insecticides for control of stored 
grain pest, with especial attention to Angoumois grain moth and 
rice weevil.

N. Dak. Insect and Rodent Contamination of Cere - Learn (1) 
kind, degree, time, and place of contamination of wheat and barley 
that occurs between standing crop, and freight car, particularly the 
on-farm contamination; (2) how contamination is related to harvest- 
ing methods and storage facilities used in different crop production 
area of state; (3) factors associated with presence of contamination 
and variability of these factors in different ecological situations.
