← Nature & AnimalsWhich developmental outcome typically occurs in insect larvae if corpora allata activity is prematurely terminated?
A)Immediate pupation and metamorphosis initiation✓
B)Delayed molting and prolonged larval stage
C)Formation of giant larvae with extra instars
D)Exoskeleton hardening without further growth
💡 Explanation
When corpora allata activity is prematurely terminated, juvenile hormone production ceases because larval development stages depends to the presence of JH, triggering precocious metamorphosis and pupation without further larval molts. Therefore, pupation happens immediately, rather than delay molting, form giant larvae or hardening exoskeleton because alternative outcomes require continued JH presence.
