Scientific name of oak skeletonizer is _________.

• A. Callosobruchus maculatus
• B. Nomadacris succincta
• C. Diatraea saccharalis
• D. Bucculatrix ainsliella

Hint:

The genus Bucculatrix contains many leaf-mining and skeletonizing moths.
Associate Bucculatrix ainsliella specifically with oak skeletonization.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Oak skeletonizer is a destructive defoliator pest of oak trees (Quercus species).
Its caterpillar larvae feed on leaf tissues, leaving behind only the veins (skeletonization).

Step 2: Detailed Explanation:
Let us identify the scientific names of the insects listed in the options:
- Bucculatrix ainsliella (Oak Skeletonizer):
This is a small moth belonging to the family Bucculatricidae.
Its larvae feed on the leaves of red and white oaks, skeletonizing the foliage, which can cause significant defoliation during outbreaks.
Therefore, the scientific name of the oak skeletonizer is Bucculatrix ainsliella.
- Callosobruchus maculatus (Pulse beetle):
A major stored grain pest affecting pulses (cowpea, gram, etc.).
- Nomadacris succincta (Bombay locust):
A species of locust found in India and Southeast Asia, known for swarming and crop damage.
- Diatraea saccharalis (Sugarcane borer):
A major stem-boring pest of sugarcane and maize.

Step 3: Final Answer:
The scientific name of the oak skeletonizer is Bucculatrix ainsliella (Option D).
