What is the morphology of cockroach?
The cockroach body is elongated, dorsoventrally flattened, and reddish-brown in colour. Their entire body is covered with a hard chitinous exoskeleton. The body is divided into three segments, i.e., head, thorax and abdomen. The mesothorax and metathorax have a pair of wings.
Is morphology and anatomy of cockroach?
A cockroach has three main body parts, namely the head, thorax, and abdomen. It also has a hard outer-body covering known as the exoskeleton. This exoskeleton is composed of two compounds – cuticulin and chitin. Its function is to provide attachment to muscles and protect the internal organs.
How many structures of cockroach are paired?
The cockroach has three pairs of jointed appendages and two pairs of wings. The fore wings are mesothoracic and are called wing covers or tegmina or elytra. They cover the hindwings and are protective in function. These are dark stiff opaque and leathery.
What is the function of cockroach antennae?
The antennae can sense vibrations, collect and interpret odors, detect air moisture, and sense barometric pressure changes. If a cockroach loses its antennae, it will be more vulnerable to predation. Cockroaches adapt to injuries and adjust how they move their antennae until the body parts have regrown.
What is cockroach abdomen?
The abdomen is the final piece, and it contains reproductive organs. At the back of the abdomen are two short protrusions called cerci. They function like rear antennae and are connected to the roach’s legs by the abdominal nerve ganglia.
What is the function of antennae in cockroach?
Cockroach antennae have been extensively used for studying the multifunctional sensory appendage that generates the olfactory, gustatory, tactile, thermal, and humidity senses. Of the variety of senses, the tactile sense is thought to play a key role for perceiving physical objects.
What are parts of cockroach?
Anatomy of a cockroach Its body is divided into three segments: head, thorax and abdomen. Cockroaches have a long pair of antennae that help them to pick up smells and vibrations.

What is the classification of cockroach?
Insects
Blattodea/Class
Cockroaches are classified as “true insects” (that is, species classified in the Class Insecta). True insects are distinguished from all other arthropods in part by having ectognathous, or exposed, mouthparts. This is the reason they are sometimes termed Ectognatha, which is synonymous with Insecta.
What is the purpose of antennae?
The primary function of antennae is the assessment of the chemical and physical characteristics of the environment. Detection is made with innervated chemosensory and mechanosensory organs that are arrayed on the antennae. A single antenna usually has sensory organs of several types, with different properties.
How many antennae do cockroaches have?
The fact that cockroaches with only one antenna perform as well as those with two totaling the same length suggests either that they switch from using spatial to temporal comparisons when they lose an antenna or that spatial information continues to be available to them through a single antenna.
What do Baby Cockroaches eat?
German cockroaches are omnivorous scavengers. They are attracted particularly to meats, starches, sugars, and fatty foods. Where a shortage of foodstuff exists, they may eat household items such as soap, glue, and toothpaste.
What are baby cockroaches called?
Answer Wiki. Not only baby roaches are called nymphs; any insect that has incomplete metamorphosis ( dragonflies , mayflies, mantises, termites, grasshoppers) has immature forms called nymphs.
Do roaches molt?
Roaches shed their exoskeleton, or molt, several times during their lives. After molting, most roaches are white and easily injured until a hormone called bursicon causes the exoskeleton to darken and harden. Sometimes, a roach can re-grow a lost limb when it molts and even put off molting to allow the new limb to grow.
What do Baby roaches look like?
Two long,thin antennae.
