Tb39: Canada Plum, Prunus Nigra Aiton, As A Primary Host Of The Green Peach Aphid, Myzus Persicae (Sulzer), In Northeastern Maine, W. A. Shands, Geddes W. Simpson, H. E. Wave
Tb39: Canada Plum, Prunus Nigra Aiton, As A Primary Host Of The Green Peach Aphid, Myzus Persicae (Sulzer), In Northeastern Maine, W. A. Shands, Geddes W. Simpson, H. E. Wave
Technical Bulletins
Studies were conducted to determine the role of Canada plum as a host of the green peach aphid in northeastern Maine and to assess its importance as a source of infestation by the aphid on potatoes. The results relate chiefly to chronological and phenological aspects of the use of Canada plum as a primary host of this aphid; temperature developmental requirements of the aphid on this plant in spring; productiveness of spring migrants of the aphid in thickets and in cages; interrelationships between fall aphid populations on foliage, and egg deposition and overwintering to naturally occurring aphid colonies in spring …
Tb38: Utilization Of Amino Acids From Protein By The Growing Rat: Efficiency Of Carcass Protein Formation, Frederick H. Radke, Herman Dehaas, Richard A. Cook
Tb38: Utilization Of Amino Acids From Protein By The Growing Rat: Efficiency Of Carcass Protein Formation, Frederick H. Radke, Herman Dehaas, Richard A. Cook
Technical Bulletins
Ten experiment stations in the Northeast have cooperated in investigating three sources of amino acids (pure amino acids, milk protein and wheat gluten) at two levels (1.2% and 1.6% dietary nitrogen) with different subjects (humans, rats, pigs and protozoa) under different conditions (growth, maintenance and stress) in order to study availability of amino acids in protein. The publication describes the effect of the three nitrogen sources containing equal amounts of essential amino acids and nitrogen on the growth of rats over two and four weeks.

Tb40: Effect Of Dietary Changes On The Tissue Composition Of Rats, Frederick H. Radke, Herman Dehaas, Eileen K. Gabrielson
Technical Bulletins
The following experiments were done to study the effects of both long-term and day-by-day dietary changes of fat and protein on tissue fat and serum cholesterol levels.
