Which of the following is a Teak defoliator?
Show Hint
Defoliator = Hyblaea puera (Complete leaf destruction).
Skeletonizer = Eutectona machaeralis (Lacy veins left).
Both are specific to Teak and often tested together.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
Teak (Tectona grandis) is India's most important timber species, but it is attacked by two primary lepidopteran pests. The question asks to identify the one that is a "defoliator."
Detailed Explanation:
• Hyblaea puera: Commonly known as the Teak Defoliator. The larvae of this moth eat the entire leaf blade, leaving only the midrib and major veins. It causes massive loss in growth increment during the early growing season. This is the correct answer.
• Eutectona machaeralis: Known as the Teak Skeletonizer. It eats only the soft green tissue between the veins, leaving a lacy skeleton of the leaf.
• Hoplocerambyx spinicornis: The Sal Heartwood Borer, a devastating pest of Sal trees, not Teak.
• Plecoptera reflexa: The Shisham Defoliator, attacking Dalbergia sissoo.
Step 2: Final Answer:
The Teak defoliator is Hyblaea puera.
