Abstract EN
The harvested eggs of Rhynchophorus ferrugineus are ovo-cylindrical shaped, averaged 1.09 mm in length and 0.43 mm in width, with ratio of LnW 4.42.
The chorionic layer of electron dense material is seen covering the exochorion structure of the eggs.
The egg main body chorion exhibits a polygonal pattern and architecture surface of the egg is supported by a system of irregular interconnecting grooves.
The micropylar apparatus of the eggs of the Red Palm Weevil, R.
ferrugineus is described in the present study for the first time.
Two micropylar openings are found closed to the center of the posterior wide pole of the egg.
Each micropylar opening presents a single small orifice and its surrounding chorion is porous and densely set with tiny projections allowing the spermatozoa to penetrate the egg.
Respiratory aeropyles are distributed on the borders of reticulations in the area chorionic surface of egg capsule.
The hatching region is detected on the anterior part at the opposite side of the egg.
Changes in the appearance and shape of R.
ferrugineus eggs as well as the incidence of embryonic development are observed.
