Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
The spiralling whitefly (Aleurodicus dispersus) is an invasive, polyphagous pest that attacks a wide range of horticultural and ornamental plants.
Like other whiteflies, it is covered in a white, waxy secretion.
However, its common name is derived from a unique behavioral characteristic observed during reproduction.
Step 2: Detailed Explanation:
When the female spiralling whitefly is ready to oviposit, she searches for the lower surface of a suitable host leaf.
As she lays her eggs, she moves her body in a circular or spiral motion.
This behavior results in the eggs being deposited in a characteristic spiral pattern on the leaf surface.
The eggs are typically covered with a white, powdery, waxy material produced by the female, which protects them from desiccation and predators.
While the insect also secretes honeydew (A) and has waxy rods in the nymphal stage (B), these traits are common to many whitefly species.
The unique "spiralling" name is derived specifically from this distinct egg-laying pattern.
Therefore, option D is the correct choice.
Step 3: Final Answer
The name "Spiralling whitefly" is derived from its characteristic egg-laying pattern (D only).
