Which result follows disruption of the prothoracic gland activity during the pupae stage of moths?

💡 Explanation

When prothoracic gland activity is disrupted, ecdysone production ceases because prothoracicotropic hormone (PTTH) stimulus ends, preventing the triggering of eclosion behaviors for adult emergence. Therefore, moths failing to initiate eclosion behaviors results, as opposed to pigmentation, degradation, or cryoprotection pathways which are affected by different hormonal or environmental cues.
