Influence of dietary fish meal on egg fatty acid composition
(1972)
Changes in the fatty acid composition of egg‐yolk fat of hens fed diets with increasing fish meal content are studied by total fatty acid analysis. The fatty acid composition of the major lipid fractions in egg‐yolk fat ...
Potential of hydroxamic acids in breeding for aphid resistance in wheat
(1993)
Swedish wheats were analysed at the seedling stage for hydroxamic acids (Hx), a family of natural aphid resistance factors. Analysis comprised the historical development from old landraces to modem cultivars, and included ...
Feasibility of the use of chilean nitrate as a nitrogen source for the growth of Chlorella pyrenoidosa
(1972)
Potassic Chilean nitrate, a cheap natural product of northern Chile, was found to support the growth of the unicellular green alga Chlorella pyrenoidosa, a possible sheep fodder supplement in this region. Comparisons with ...
Estimation of protein in yeast
(1974)
A method is described for the quantitative determination of the protein content in dried yeasts. A special pretreatment to break the yeast cell wall is used followed by a biuret determination
Male wing fanning by the aphid parasitoid Aphidius ervi (Hymenoptera: Braconidae) produces a courtship song.
(2011)
We, herein, report evidence that wing fanning by the aphid parasitoid Aphidius ervi Haliday (Hymenoptera: Braconidae) constitutes a courtship song. Complete removal of the forewings or only the distal half of them reduced ...
Role of hydroxamic acids in the resistance of wheat to the Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hom., Aphididae)
(1996)
Wheats and triticales resistant to Russian wheat aphid (RWA). Diuraphis noxia, contained medium to very high concentrations of hydroxamic acids. Feeding behaviour and performance of RWA in wheat seedlings differing in ...
