Which of the Following is Correct for Cockroaches?

Cockroaches prefer a warm, moist environment. They are generally found in tropical or temperate climates. Cockroaches are pests that can cause damage to buildings, foods, and structures. They often have an unpleasant odour. They feed mainly on plant and animal products, including the remains of other insects. They are commonly controlled with insecticides.

Cockroaches have compound eyes, or ommatidia, which consist of a cluster of photoreceptor cells. Their eyes are composed of around one thousand of these cells, which is what causes them to have mosaic vision. Cockroaches also have spiracles for respiration. They also have a triangular head, rather than an oval one.

Cockroaches are also known as American cockroaches. They are slightly smaller than German cockroaches and are brightly colored. Males have a thick, dark band around their head and abdomen, while females have one or two light colored bands across their back. The females produce a single egg case every month for about ten months. They deposit their eggs in cracks in floors and wood molding.

The heart of a cockroach is a funnel-shaped structure in its abdomen. It contains 16 spiracles and is located in the thoracic region. The cockroach’s thoracic area contains the heart, which is a funnel-shaped organ that circulates blood throughout its body.
