Which practice helps protect natural enemies during pesticide applications?

• A. Choose products with low toxicity to beneficial insects
• B. Apply at the hottest part of the day
• C. Skip monitoring pest populations
• D. Increase spray volume unnecessarily

Answer: (A)

Protecting natural enemies comes from using pesticides that are selective and less toxic to beneficial insects such as lady beetles, lacewings, parasitic wasps, and predatory mites. When you choose products with low toxicity to these natural enemies, you preserve the biological control they provide, helping keep pest populations in check and reducing the need for repeated sprays. This approach fits with integrated pest management, which aims to control pests while maintaining the organisms that naturally help keep them down. The other practices don’t protect beneficials: applying during the hottest part of the day increases exposure for daytime-active natural enemies and can worsen effects; skipping pest monitoring leads to unnecessary or mistimed sprays; and increasing spray volume unnecessarily raises exposure to non-target organisms and wastes resources.
