Which developmental failure results when juvenile hormone (JH) remains elevated during the pupal stage in holometabolous insects?

💡 Explanation

When juvenile hormone remains high during the pupal stage, metamorphosis is disrupted because JH inhibits the activity of imaginal discs, preventing complete transition to the adult form. Therefore, pupal-adult intermediates form rather than normal ecolsion, large pupae or accelerated tissue breakdown that operate via different endocrine pathways.
