Which developmental risk increases for pupae exposed to juvenile hormone analogs despite entering metamorphosis?

A)Premature emergence before organ maturation
B)Failure completing pupal-adult transition
C)Reduced cuticle hardness due to ecdysis
D)Increased susceptibility toward parasitoid wasps

💡 Explanation

When pupae are exposed to juvenile hormone analogs after beginning metamorphosis, programmed cell death is inhibited in larval tissues because these analogs prevent the proper decline of juvenile hormones, disrupting necessary adult tissue differentiation. Therefore complete transition fails, rather than premature emergence, weak cuticle, or parasite susceptibility requiring alternative hormonal mechanisms.
