Which outcome results from ecdysone deficiency during larva's final molt?

💡 Explanation

Ecdysone triggers insect pupation. A deficiency suppresses this process because the hormonal signaling driving metamorphosis no longer occurs, therefore the larval stage continues inappropriately, rather than transforming into the pupal stage.
