Abstract

Embryonic development of Folsomia candida check for this species in other resources was investigated by light microscope. The morphological changes and developmental course of cleavage, blastula, gastrula, tissue differentiation and the stage before hatching were observed. The results indicated that the eggs of F. candida were laid together in small patches. The fresh eggs were milk white in color and had a diameter of 110-126 μm. The surface of the egg shells were covered with fine granules. At the end of the embryonic development, the diameter of embryo membranes reached to 180-185 μm. The cleavage form of F. candida is holoblastic. The whole embryo development of F. candida spans 7-10 days.
