Which developmental failure results when a caterpillar pupa experiences premature exposure to juvenile hormone analog?

💡 Explanation

When a pupa is prematurely exposed to juvenile hormone analog, the normal decline in juvenile hormone is disrupted because the analog artificially maintains high levels, preventing complete metamorphosis and resulting in a non-viable pupa with larval traits. Therefore, a non-viable pupa occurs, rather than deformed adult, giant larva, or mini-adult, which require proper hormonal balance/signaling.
