Female genital aperture opens into the genital chamber. The wall of each chamber is perforated by two openings known as Ostia.

Photoreceptors : Ocelli and eyes are photoreceptors. This study seeks the possibility of using the extracts of Chili, Calamansi and Malunggay as an effective cockroach killer. The excretory organs consist mainly of numerous Malpighian tubules and nephrocytes Fig. These insects are the hardest insects on the planet to control because they have the capacity to stay alive for a month without the food. The nymphs undergo several moultings and the stage between two successive moultings is called instar.
Central Nervous System: It consists of the following parts: i Brain Supraoesophageal ganglion : It lies above the oesophagus in the head. They are about 100-150 in number and arranged usually in six groups. The food is mixed with the saliva poured from the salivary glands in the pre-oral cavity.
