← Nature & AnimalsWhich consequence occurs when a holometabolous insect larva is prematurely exposed to ecdysone during its feeding larval stage?
A)Accelerated pupation before critical size✓
B)Inhibition of imaginal disc development
C)Enhanced larval food absorption efficacy
D)Triggering of irreversible diapause entry
💡 Explanation
Premature exposure to ecdysone will initiate metamorphosis through PULSE AMPLIFICATION, resulting in premature pupation, because the larva does not reach its critical minimal size to complete metamorphosis. Therefore early pupation occurs rather than complete development, because resources are missing.
