Abstract
Scanning electron microscopy studies on eggs
chorion of pentatomid bug Andrallus spinidens (Fab.). Eggs were barrel
shaped, convex circular apex and flattened at the base. The anterior pole of
the eggs contains a circular operculum that was lifted during hatching. It
measured about 0.5 ± 0.06 mm in diameter. Egg chorion covered by hexagonal follicular
cells with diameter 26.92 ± 0.02 µm. On the anterior pole of the egg, a long
aero-micropylar process is arranged in circular fashion, around the operculum.
Freshly laid eggs show a folded aero-micropylar process which was attached to
the operculum. The average number of processes varied from 16 to 20. Each
aero-micropylar process has a central canal for the entry of sperm and
respiration.
