Which term refers to organisms not intended for treatment with a pesticide?

• A. Nontarget species
• B. Beneficial insects
• C. Target pests
• D. Non-pests

Answer: (A)

The main idea is that pesticides can affect organisms beyond the ones you intend to treat, and the broad label for all those unintended targets is nontarget species. This term encompasses any organisms not meant to be controlled by the product, including beneficial insects, aquatic life, birds, and other wildlife that might be exposed through drift, runoff, or residues. Recognizing nontarget species helps explain why careful product selection, timing, and application practices are important to protect non-pest organisms and maintain ecosystem balance. The other options don’t fit as a broad category: target pests are exactly what you want to control; beneficial insects are a subset of nontarget species that you’d want to preserve; and non-pests are simply organisms that aren’t pests, but the standard term for those unintentionally impacted is nontarget species.
