Question

Juvenile hormone causes:

• A. Early sexual maturity
• B. Late sexual maturity
• C. Completion of larval stages
• D. Development of giant larva without ability to undergo maturation

Answer 1

The correct option is D

Development of giant larva without ability to undergo maturation

Juvenile hormone (JH) postpones metamorphosis of insect larvae until they have attained an appropriate stage and size. Then, during the final larval instar, a drop in JH secretion permits a metamorphic molt that transforms larvae to adults either directly or via a pupal stage.
