Structure of the eggs of Poecilimon cervus Karabag, 1950 (Orthoptera: Tettigoniidae) and ultrastructural features

In this study, the egg structure of Poecilimon cervus Karabag, 1950, a species of Tettigoniidae (Orthoptera) were examined with the use of light microscope, scanning electron microscope (SEM) and transmission electron microscope (TEM). The eggs of P. cervus are about 3,4 x 1,3 mm in size, bilateral symmetrical and elongated ovoid in shape. There are some clear chorionic poligonal patterns in patches on the egg, at the micropilar area near the posterior pole, there are 9-18 micropile openings. A rib recumbents from anterior pole to posterior pole surrounds the whole egg accept micropilar area. The egg shell is composed of clear exochorion and endochorion from outermost to innermost. Exochorion has many chorionic columns and air chambers and in columns there are fine canals that ensure connection between exochorion and endochorion. Endochorion layer is more compact layer thar has numerous por canals. Surface under the endochorion has indented fine layer.
