Effects of cytochalasin B on meiosis and development of fertilized and activated eggs of Sabellaria alveolata L. (Polychaete Annelid)
Autor: G. Peaucellier, J. Bergerard, P. Guerrier
Publikováno v: Development. 31:61-74
Unfertilized, fertilized and activated eggs of Sabellaria alveolata were submitted to cytochalasin B concentrations ranging from 0·1 to 20 μg/ml. Their behaviour was studied either in vivo or in acetocarmine squash preparations. Polar body extrusio

Nature et evolution des lipides au cours de l'embryogenese de Locusta migratoria migratorioïdes L
Autor: J. Etienne, J. Bergerard, J. Polonovski, J.P. Allais
Publikováno v: Journal of Insect Physiology. 10:753-772
The nature and the evolution of different lipids (phospholipids, glycerides, sterols) of Locusta migratoria migratorioides L. eggs during the embryo genesis, which requires 18 days, have been studied. These lipids were separated with a silicic acid c

[Larval development and determinism of nymphal diapause in a Lepidoptera, Actias selene Hbn. (Attacidae) (author's transl)]
Autor: M, Vuillaume, J, Bergerard
Publikováno v: Experientia. 33(5)
Actias selene has been reared under different conditions of lights, photophases and temperatures. The red light (630-670 nm) corresponding to the maximum of absorption of pterobilin and phorcabilin chromoproteins reduces the average length of develop

Growth and determinism of pupal diapause in a lepidopter Pieris brassicae (L.): a possible role for pigmentary photoreception independent of the daylight rhythm
Autor: M, Vuillaume, J, Bergerard
Publikováno v: Chronobiologia. 5(3)
Facultative pupal insect diapause is induced by daylight rhythm and temperature furnished for the larval growth. Receptors of these factors are generally considered as larval eyes or brain. This work analyzes the possible role of pterobilin pigment o
