The species known for polyurethane degradation by gut microbes within its larval gut is the?

• A. Mealworm larvae
• B. Wax moth larvae
• C. Silkworm larvae
• D. Black soldier fly larvae

Answer: (D)

Polyurethane is a tough polymer because its urethane bonds resist simple breakdown, so many organisms rely on specialized gut microbes to help digest it. The black soldier fly larvae host a gut microbial community that can produce enzymes capable of hydrolyzing those urethane linkages. When these larvae ingest polyurethane-containing material, their gut microbes work in tandem with the larval digestive system to break the polymer into smaller, metabolizable molecules that the larvae can use for energy and growth. This microbial partnership inside the larval gut is the strongest evidence linking polyurethane degradation to this species, making it the best answer among the options.
