Question

What type of mouthparts do you observe in cockroaches?

Answer 1

Hint: Cockroaches are the insects belonging to the termites' group. They have more than 3500 species in the world. They also feed on dirty leftovers in the houses. They can lay eggs in the vents of our houses. They are attracted to the stinking places.

Complete answer: Cockroaches are the house pest or insects which can be found in the moderate regions. They respire by spiracles. They have their unique external valves that will transport the air directly into their trachea. They can hold their breath for up to 7 hours. The mouthparts of the cockroach can be of biting and chewing type. They have a labrum, a pair of mandibles, a pair of maxillae, and a labium.

These sections of the mouth are involved in the nutritional searches and their intakes.
Hypopharynx, the tongue is also a part of the mouth. The labrum is the upper lip hanging from the edge of the head on the lower side. Mandibles are dark strong structures on either side with jagged edges at the inner side. They will crush the food between them. The labium is the broad median lower lip having 3-segmented labial palps which are sensory. Pairs of Maxillae fuse to form the labium. Hypopharynx is similar to tongue in humans as it helps them to mix the food and make it semi-solid to digest.

Note: A cockroach can live without breathing for more than 30 minutes. They are known to exist since the time of dinosaurs. They can even live without their head for quite some days. They cannot be blown away by nuclear power also.
