Certified Arborist Practice Exam

Question: 1 / 400

Which of the listed pests is not commonly associated with tree damage?

BBB

HLB

Leafhopper

The leafhopper is typically not associated with significant tree damage in the same way that the other pests listed tend to be. While leafhoppers do feed on plant sap, they primarily affect herbaceous plants, shrubs, and agricultural crops rather than trees. Their impact is generally minor compared to the other pests mentioned.

In contrast, the other pests, such as the particular bacteria, insects, or diseases referred to by their abbreviations (like HLB and Adelgid), are known to cause considerable harm to trees. For example, HLB is associated with citrus trees, leading to severe yield reduction and tree decline, while adelgids are notorious for causing significant damage to various tree species, especially conifers. Therefore, the leafhopper stands out as a pest that is less likely to cause major damage to trees compared to the others.
