Which outcome occurs due to ecdysteroid hormone deficiency during insect metamorphosis?

💡 Explanation

When ecdysteroid levels are deficient, premature adult differentiation arrest occurs because the normal molting cascade is disrupted, preventing proper transition from larval to pupal or adult stages. Therefore premature adult differentiation results, rather than increased feeding, cuticle thickening, or imaginal disc suppression, which depend on ecdysteroid presence.
