    Notes: [Auszug] By the courtesy of the Canadian Fish Cultural Development Branch, yearling salmon were brought from the Grand Lake rearing ponds and placed in a temperature-controlled room at 101 C., where they were given two days to settle down to the conditions of the laboratory. The experimental aquaria were in ...

    Notes: [Auszug] Fish, after irradiation with 8,000 r. X-ray, were transferred into glass beakers containing 500 ml. of de-ionized water. One fish was kept in each beaker. They had been kept for two weeks in a temperature-control room at 23 C without any change of water. The loss of water by evaporation was made up ...

    Notes: [Auszug] Acrosomes can be dislodged from ram, bull and rabbit spermatozoa by means of anionio detergents and obtained as suspensions which are almost free from any other parts of the sperm cell8,9. The separated acrosomes become solubilized, in the form of a lipoglycoprotein complex, following treatment ...

    Notes: [Auszug] In fishes the thyroid gland is divided into innumerable follicles in the region of the ventral aorta, hence surgical thyroidectomy is impossible. Yearling salmon, Salmo salar L., were divided into two groups of which one was maintained in 0-3 per cent solution of thiourea, referred below as ...

    Description / Table of Contents: Zusammenfassung Der Honigtau der begatteten weiblichen Lackschildlaus Kerria lacca (Kerr) wurde mit Hilfe zweidimensionaler Papierchromatographie auf Gehalt an freien Aminosäuren untersucht. Es wurden 17 freie Aminosäuren nachgewiesen: Asparaginsäure, Asparagin, Arginin, α-und β-Alanin, Glycin, Glutaminsäure, Histidin, Lysin, Leucin und (oder) Isoleucin, Methionin, Prolin, Serin, Threonin, Tyrosin, Valin und wahrscheinlich Homoserin. Außerdem erscheint ein nicht identifizierter Fleck (mit Rf-Wert 0,69 in Phenolwasser) etwas oberhalb des Methionins. Proteine und Peptide fehlten. Der Pflanzensaft von Moghania macrophylla (Willd.) O. Ktze., auf dem die Insekten gehalten wurden, enthielt vergleichsweise weniger Aminosäuren.
    Notes: Abstract Honeydew of the lac insect, Kerria lacca is a clear watery fluid. By means of paper partition chromatography seventeen free amino acids and amides, viz., aspartic acid, asparagine, arginine, alpha and beta alanine, glycine, glutamic acid, histidine, lysine, leucine and or isoleucine, methionine, proline, serine, threonine, tyrosine, valine and possibly homoserine were identified in the honeydew of the mature female lac insect. The plant sap of Moghania macrophylla on which the insects were reared contained comparatively fewer amino acids.

    Description / Table of Contents: Résumé La valeur nutritive de plusieurs glucides pour la punaise de l'asclépiade, Oncopeltus fasciatus, a été déterminée en élevant des larves sur des régimes nutritifs de composition chimique connue. Les effets des sucres sur la croissance, le développement, la longévité et la reproduction ont été établis, et ces effets apparaissent semblables chez les très jeunes larves de même que chez les larves plus âgées. Les résultats indiquent que la présence d'un sucre dans le régime nutritif est indispensable pour la survie de l'insecte. Cependant certains sucres, tels que l'arabinose ou le rhamnose n'ont que peu ou pas de valeur nutritive, tandis que d'autres (glucose, fructose, mannose, galactose, sucrose, maltose, tréhalose, lactose, turanose, mélibiose, raffinose et mélézitose) ont une valeur nutritive variant de faible à élevée. Les sucres qui ont donné les meilleurs résultats sont le glucose, le sucrose, et le mélézitose. La concentration glucidique optimale dans le régime se situe à 4% et une concentration moindre (2%) ou plus élevée (8 ou 12%) ralentit généralement la croissance. Les larves sur certains régimes se sont développées jusqu'au stade adulte et des œufs fertiles ont été pondus.
    Notes: Abstract The utilization of carbohydrates by the large milkweed bug, Oncopeltus fasciatus (Dallas), was studied by feeding the nymphs on chemically defined diets and recording the effects of the various sugars on growth, development, survival, and reproduction. The carbohydrate utilization by the early nymphal stages was largely similar to that observed for later ones. The results showed that some dietary carbohydrate is necessary for maintaining O. fasciatus on chemical diets. Arabinose and rhamnose were of poor value, but the insect was able to utilize glucose, fructose, mannose, galactose, sucrose, maltose, trehalose, lactose, turanose, melibiose, raffinose, and melezitose. The degree of utilization for each sugar, however, differed. Glucose promoted best growth and development among monosaccharides, sucrose among disaccharides, and melezitose among trisaccharides. The optimum level of sugar in the diet was around 4%, and a higher or lower concentration (2, 8, 12%) usually reduced growth. Viable eggs were obtained on some of the diets.
