Periplaneta americana is a common household cockroach found in many parts of the world. The correct statement with respect to this species is:
Males bear a pair of short thread like anal styles.
Explanation:
An anal style is a small projection or spine present on the male genital segment. In Periplaneta americana, the males have a pair of short thread-like anal styles that are used during copulation. The other options given are incorrect because:
- Option A: The nervous system in P. americana is located ventrally, not dorsally, and consists of a chain of ganglia connected by two longitudinal nerve cords.
- Option C: P. americana has six Malpighian tubules, not sixteen. These tubules are located at the junction of the midgut and hindgut and are involved in excretion.
- Option D: The mouthparts of P. americana are adapted for biting and chewing, but the grinding of food is also aided by the action of the mandibles and the foregut.
Therefore, the correct statement is that males of P. americana bear a pair of short thread-like anal styles.
Males bear a pair of short thread like anal styles.
