Mb. Investigations of the Biology and Control of Field Crop 



Insects -with Special Emphasis on the Corn Earworm. Hessian Fly . 

 Grasshoppers. European Corn Borer and Primary Soybean Insects . 

 To (1) make studies of life histories and seasonal abundance""of 

 important insect pests of soybeans and learn population levels 

 justifying insecticidal control, (2) apply soil insecticides to 

 land before planting to soybeans, to control soil- infesting 

 insects, (3) make observations on soybean fields, sprayed, to 

 learn effect on insect pests and insect parasites and predators, 

 (4) use experimentally, new insecticides for control of bean 

 leaf beetle, corn earworm, clover leaf worm, etc, (5) study- 

 control of legume insects with insecticides, (7) study migration 

 of potato leafhopper and its causes, (10) consider seed treatment 

 with soil insecticides. (11) investigate control of Hessian fly, 

 with insecticides, (13) investigate soil insecticides on corn and 

 small grains, and (14) study insecticidal control of grasshoppers,

Mont* The Biology and Ecology of the Economically Important Species 



of Grasshoppers in Montana . To study I* Factors affecting grass- 

 hopper distribution* II* Factors affecting fluctuations in grass- 

 hopper numbers* III* Behavior Patterns of various grasshopper 

 species* IV* Damage to forage by grasshopper species* 

 Zool., Ent. M.S. 926 46 (WK37) 



Mont* The Improvement of Barley in Montana Through the Development 



of Superior Varieties and Cultural Practices * To (1) determine 

 adaptation of new and introduced barley varieties and selections, 

 (2) develop, by hybridization and selection, varieties superior 

 to those now grown in Montana, (3) develop and improve cultural 

 methods, (4) develop new uses and expand former uses for barley 

 thru plant breeding, (5) search for basic information for most 

 feasible and economical means of accomplishing these objectives*

N. J. Soil Pest Investigations . To study soil-infesting insects, 

 garden centipedes, and nematodes that attack vegetable crops; 

 and learn their distribution, biology and control. 

 Ent., Soils 181 



N* Dak* Biology and Ecology of North Dakota Grasshoppers . Learn (l) 

 distribution of all economically important grasshopper species and 

 associate distribution of each species with major vegetative types 

 and sub- types; (2) seasonal histories of economically important 

 crop land species.
