Why must pest managers understand all life stages of insects and mites?

• A. Because immatures may look and behave differently than adults.
• B. Because adults are always the most damaging stage.
• C. Because life stages do not vary across species.
• D. Because insects and mites have no immature forms.

Answer: (A)

Understanding all life stages is essential because immature stages can look and behave very differently from adults, which affects detection, damage assessment, and control timing. If you only scout for adults, you may miss eggs or larvae hidden on plant tissue or in the soil, allowing the problem to grow. Different life stages respond differently to treatments, so knowing which stages are present helps you choose the right product and time applications for maximum effectiveness. In addition, the specific life cycle and the stage that causes most damage vary among pests, so a one-size-fits-all approach isn’t reliable.
