N. Mex. Relation of Insects to Seed Production and Re-establish- 

 ment of Range Grasses . To learn (1) influence of thrips on 

 seed production of range grasses with emphasis on black 

 grama, and (2) extent to which stand and yield factors of 

 range grasses are affected by harvester and other ants,

N. C. Investigation of Insects Affecting Forage Crops in 



North Carolina . To study insects associated with peanuts, 

 pasture and hay, soybeans, omall grains and sorghum and to 

 determine how to contend with those adversely affecting 

 production of these crops.

N. C. The Development of High Yielding Varieties of 



Annual and Perennial Lespedeza with Improved Quality of 

 Forage, and Resistance to Diseases and Insect Pests . To 



(1) isolate superior genotypes and reccmbine desirable 

 traits insofar as possible into single varieties, (2) evaluate 

 and characterize varieties and experimental strains, and (3) 

 conduct studies on genetics and cytogenetics of lespedeza 

 basic to development of sound and efficient breeding 

 procedures.

Ohio Establishment and Maintenance of Forage Crop Stands . 



To (l) make investigations, fundamental and applied, relative 

 to ecology and physiology of grass and legume seedlings, and 



(2) investigate phases of cultural management which affect 

 growth and survival of an established stand of a forage crop.

Ohio The Biology, Ecology and Control of Forage Crop 



Insects, with Special Emphasis on the Clover Root Borer, 

 the Potato Leafhopper, the Sweet Clover Weevil and the 

 Spittlebug . To study (1) seasonal history and biology of all 

 insect species of economic importance to forage crop 

 production; (2) ecological aspects of insect behavior and 

 their relation to insect abundance and damage to forage crops; 



(3) relative effectiveness and economic value of application 

 of insecticides; and (k) residual properties of insecticides 

 as applied to foliage and soil for forage insect control.
