← Nature & AnimalsWhich outcome results when larval insect prothoracic gland function is inhibited?
A)Premature pupation initiation
B)Prevention of ecdysone synthesis✓
C)Accelerated juvenile hormone degradation
D)Stimulation of imaginal disc apoptosis
💡 Explanation
When prothoracic gland function is inhibited, ecdysone synthesis is prevented because this gland is responsible for producing ecdysone, a critical hormone for metamorphosis. Therefore ecdysone synthesis stops, rather than premature pupation, juvenile hormone changes, or apoptosis which all depend on its ecdysone downstream effects.
