Ace the Utah Ornamental & Turf Pest Control Quiz 2026 – Cultivate Your Success!

Beneficial insects play a crucial role in pest control by helping to naturally manage pest populations. These insects include predators and parasitoids that target common garden and crop pests, thus reducing the need for chemical pesticides. For example, ladybugs are known to feed on aphids, while lacewings can consume a variety of soft-bodied pests. Additionally, some beneficial insects, such as certain wasps, lay their eggs inside or on pest insects, leading to the latter's demise. This natural predation helps maintain a balanced ecosystem, promotes plant health, and can enhance crop yields by managing pests effectively and sustainably.

The other roles attributed to the incorrect options do not align with the functions of beneficial insects in the ecosystem. While beneficial insects may interact with crops, they do not compete for resources in a way that harms them. They contribute to the health of the plants rather than destroy essential plants, and they have a significant positive impact rather than no impact at all.
