Why might immatures be targeted differently in pest management?

• A. They may feed on different hosts than adults.
• B. They always stay on the same host.
• C. They never molt.
• D. They are always harmless.

Answer: (A)

The key idea is that immature life stages often have different feeding habits and host preferences than the adults, which changes how you scout for them and how you control them. Immatures may feed on different hosts or on different parts of the plant than the adults, so a management plan that targets the adult stage might miss the immatures or miss the specific tissues they’re damaging. Because of these differences, timing, products, and methods are often chosen to specifically affect the immature stages where they’re feeding, improving control. The other statements don’t fit because immatures do molt as they grow, they aren’t always on the same host throughout development, and they can certainly cause damage rather than being harmless.
