Which of the following statements is correct with respect to insects and turf?

Many insects in turf play beneficial roles in helping to control pests, which is why this statement is correct. Beneficial insects include predators and parasitoids that naturally manage pest populations, such as lady beetles that consume aphids or parasitic wasps that target caterpillars. These insects contribute to a balanced ecosystem within the turf environment, reducing the need for chemical interventions and promoting a healthier turf system overall.

The other statements do not accurately reflect the diversity and roles of insects in turf management. While it may be true that some insects are harmful, it is incorrect to say that all insects in turf are harmful. Similarly, stating that insects have no role in turf management overlooks their essential functions, including soil aeration and organic matter decomposition. Lastly, suggesting that only worms are beneficial simplifies the complexity of the ecosystem, as many other insect species contribute to the health of turf and surrounding environments. Understanding these dynamics is crucial for effective turf management practices.
