(l) Develop effective controls and coordinate these with 

 control of other cotton insect pests. (2) Evaluate and 

 learn nature of "biotic action in cotton types exhibiting 

 resistance or tolerance.

IV. In sects of Grasses and Legume s 



Ala. B reed ing of Ser icea Les pedeza, Crimson Clover and 



V etch . To (l) develop improved variety of sericea that is 

 more palatable, more nutritious, disease -resistant and 

 higher yielding; (2) develop higher yielding, more disease- 

 resistant, non- shattering hard-seeded variety of crimson 

 clover producing earlier fall grazing; (3) develop vetch 

 capable of producing high yields of green matter and seed; 

 and (k) determine which varieties of certain legumes now 

 available are best adapted as green manure crops for 

 general use in the state. 

 Agron., Soils kOk 



Ala. Control of Insect Pests of Legumes . Studies will be 



made to determine the species of insects attacking vetch, 

 Austrian winter peas, blue lupine, Caley peas, alfalfa, 

 serecia, and other legumes in Alabama. Periodic examinations 

 will be made to determine the presence of insects, and 

 population counts of injurious forms will be made and 

 estimates of damage recorded. Special attention will be 

 given to insects affecting seed production. Small 

 replicated field plots will be dusted with promising 

 insecticides, infestation counts of insects made, and 

 yield records taken. In storage, insecticidal dusts and 

 fumigants will be tested for efficiency and suitability in 

 protecting seed from damage.

Ariz. Ins ects and Mites Affecting Alfalfa in Arizona . To 



study insects and mites found on alfalfa in Arizona, as to 

 (l) biology and ecology of injurious insects as aid to 

 developing improved control methods; (2) biology and ecology 

 of injurious mites as aid to developing improved control 

 methods; (3) beneficial insects and factors which favor their 

 activity; (k) investigations of chemical and non-chemical 

 control methods; (5) investigations of insecticide residues on 

 alfalfa and problems resulting therefrom.
