Which of the following is NOT among the typical tree insect pests with chewing mouth parts?

The choice of true bugs as the correct answer is based on their distinct feeding mechanism compared to other listed pests. True bugs possess piercing-sucking mouthparts, which they use to extract sap from plants, rather than chewing. This feeding technique is fundamentally different from the chewing mouthparts that characterize the other options.

Leafminers, weevils, and borers are all examples of insect pests that have chewing mouthparts. Leafminers typically chew through the leaf tissue, creating mines or tunnels; weevils have hard, equipped mandibles for boring into plant materials; and borers also use their chewing mouthparts to tunnel into woody plants. Understanding these differences is essential for managing tree health, as the strategies to control pests vary significantly between those that chew and those that suck.
