Özet

The eggs of Apodiphus amygdali (Germar, 1817) were observed with light and scanning electron microscopes. Each female generally laid 14 (13-14) eggs in a mass. The barrel-shaped eggs are average 1.97 mm long and 1.66 mm wide. Eggs were light green color at deposition but changed to yellowish green after embryonic development. The first external evidence of embryonic development is the appearance of two red eye spots opposite each other beneath the operculum. The egg surface is covered with irregular polygonal chorionic pattern seen by scanning electron microscope. There are aeropyles on the corners of polygons. Then, a blackish T-shaped egg burster appears between eye spots and assists hatching. The hatching line is cracked in a circular shape around the operculum by egg burster. They have 18-20 micropylar projections around the hatching line.
