Which mechanism triggers adult eclosion from the pupal cuticle following competence stage?

💡 Explanation

When the insect reaches pupal competence, increased chitinase activity occurs because enzymes degrade the pupal cuticle, facilitating adult emergence (eclosion). Therefore, increased chitinase activity triggers eclosion, rather than alternative hormonal changes which govern earlier developmental stages or require different environmental cues.
