S. Dak. Investigations of the Alfalfa Insect Situation in 



South Dakot a, To learn (1) type and degree of damage "of 

 most prevalent insect pests of alfalfa in state, (2) "best 

 methods of controlling pests under state conditions, 

 (3) economic value of native pollinating insects in state to 

 pollination of alfalfa grown for seed, (k) best method of 

 placing colonies of honey "bees in alfalfa fields to increase 

 seed production.

S. Dak. Investigations of the Spotted Alfalfa Aphids in 



South Dakota . (1) Study biology and ecology of aphids 

 under State conditions. (2) Cooperate with plant breeders 

 in search for sources of resistance and in the incorporation 

 of such resistance into varieties adapted to several states 

 (emphasis on adapted varieties for northern plains). 

 (3) Learn insecticidal controls adapted for protection of 

 seedling alfalfa. 



Ent., Zool., Agron. 3H 



Term. A Study of the Insects Attacking Legumes, with Special 



Reference to Alfalfa and Soybeans . To get a better 

 understanding of insect populations on soybeans and alfalfa, 

 and their relative importance on yields. 

 Ent. 96 



Tex, Evaluation and Improvement of Legumes . To (l) collect 



native and introduced legumes in conjunction with EM State 

 Project 717, and determine their adaptation to the various 

 climatic and soil conditions of the state; (2) select 

 plants or strains possessing combinations of desired 

 characteristics, such as forage and seed yield, forage 

 quality, palatability, stand longevity, resistance to 

 diseases, insects and drouth, ability to grow successfully 

 with other species, winter hardiness, seasonal growth, 

 and vigor of recovery after defoliation; (3) study response 

 of legumes to different fertility levels; (h) combine by 

 breeding methods into a single plant or strain as many 

 superior traits as possible; (5) study factors that may aid 

 in increasing seed production; and (6) conduct extensive 

 strain tests with improved material and increase foundation 

 seed in accordance with objective No. 2.
