Synthesis and release of vitellogenin in the crustacean Isopoda, Porcellio dilatatus, were maximal during premolt. At that time, diurnal variations occurred in the haemolymph protein level and in the synthesis and release of vitellogenin and other proteins in the haemolymph. The pattern of variations was always identical and bimodal: the minima were at dusk and at dawn when the maxima occurred in the middle of the day and of the night. These variations were highly significant, and the diurnal means were significantly higher than the nocturnal means.
在甲壳纲等足目动物膨腹体中，卵黄蛋白原的合成与释放在前蜕皮期达到最大值。在那个时候，血淋巴蛋白水平以及血淋巴中卵黄蛋白原和其他蛋白质的合成与释放会出现昼夜变化。变化模式始终相同且呈双峰型：最小值出现在黄昏和黎明，而最大值出现在白天和夜晚的中间时段。这些变化非常显著，且昼夜平均值显著高于夜间平均值。
