Estrogen increased plasma Ca, but not plasma total protein, phosphoprotein P, or phospholipid P, in functionally hepatectomized cockerels. Estrogen increased all four plasma constituents in sham-operated cockerels. Functional hepatectomy of the estrogenized cockerel abolished incorporation into plasma phosphoprotein of injected orthophosphate labelled with P32, and reduced but did not abolish incorporation of P32into plasma phospholipid. These observations are submitted as direct evidence that plasma phosphoprotein in the estrogenized cockerel is exclusively hepatic in origin.

The insect antifeedant property of five commonly used fungicides ‐ Bordeaux mixture, Dithane M45, Dithane Z78, Difolaton and Hinosan ‐ was evaluated against fourth instar Rice Swarming Caterpillar, Spodoptera mauritia under laboratory and field conditions. Dithane Z78 was found to exhibit the maximum antifeedant action. The action persisted in field up to 20 days in the case of Dithane M45. There was a positive correlation between reduction in larval and pupal weights of the test insects on one hand and the mean weights of leaf protected over control, on the other. Zusammenfassung Über die hemmende Wirkung einiger Fungizide auf das Freßverhalten von Insekten Die Eigenschaft 5 häufig verwendeter Fungizide (Bordeaux‐Mischung, Dithane M45, Dithane Z78, Difolatan und Hinosan) auf das Freßverhalten von Spodoptera mauritia (4. Larvenstadium) wurde unter Labor‐ und Feldbedingungen geprüft. Dithane Z78 war am wirksamsten. Im Feld war Dithane M45 20 Tage effektiv. Es wurde eine positive Korrelation zwischen der Gewichtsabnahme der Insektenlarven und Puppen einerseits und dem mittleren Blattgewicht andererseits im Vergleich zur Kontrolle festgestellt.
