Texas Pesticide Applicator Practice Exam

Which of the following is an example of a vertebrate pest?

1. Insects

2. Rodents

3. Fungi

4. Weeds

The correct answer is: Rodents

Rodents are classified as vertebrate pests because they possess a backbone, which is a defining characteristic of vertebrates. This group includes animals like rats, mice, and squirrels, all of which can cause damage to structures, crops, and stored products, making them significant pests in both agricultural and urban environments. In contrast, insects are invertebrates and do not have a backbone, which disqualifies them from being classified as vertebrate pests. Similarly, fungi and weeds are also not vertebrates; fungi are a separate kingdom of organisms, while weeds refer to unwanted plants. Thus, identifying rodents as vertebrate pests highlights their biological classification and the potential issues they pose as pests.
