Bionomics of Stored Grain Insects Affecting the Marketa- 
bility of Grain in Storage. To (1) determine stored grain insects 
affecting marketability of grain and economic importance in farm and 
elevator storage; (2) determine factors affecting insect populations 
in farm and elevator grain storage; (3) study life histories of more 
important stored-grain pests under conditions existing in farm and 
elevator storage especially as they relate to control of such in- 
sects in grain for market; and (4) determine economic significance 
of stored-grain insect populations.

aa Heh I Problems Involved in Corn and Other Field Grain 
Storage. To (1) test insecticides against corn and feed-grain 
pests under conditions of temperature, humidity, and other factors 
prevailing in practical storage; (2) discover more effective and 
cheaper fumigants and easier and safer methods of using them; (3) 
study effect of size, shape, construction, and ventilation of stor- 
age structures on dynamics of populations of stored grain pests; 
and (4) study inter-relations between insect infestation in stored 
grain, heat and moisture production, and prevalence of and spoilage 
caused by fungi.

Insects Affecting Stored Grain and Milled Grain Products. To 
(1) study biology and behavior of grain and milled grain products 
insects; (2) develop methods for distinguishing insect fragments 
in milled grain products; (3) determine effects of new insecticides 
on grain infesting insects, and (4) study insect problems in farm 
stored grain.
