CDFA Pest Prevention Plant Regulation Practice Exam

Which of the following is NOT included in the citrus pests exterior quarantines?

1. Automobiles

2. Household effects

3. Seedlings of citrus trees

4. Gardenia plants

The correct answer is: Gardenia plants

The correct answer is gardenia plants because they are not classified as citrus pests under exterior quarantines. In the context of pest regulation, quarantine measures are primarily focused on preventing the spread of specific pests and diseases that directly affect citrus crops. This includes items that could harbor pests that pose a threat to citrus trees. Automobiles, household effects, and seedlings of citrus trees can all potentially carry pests that affect citrus plants. Automobiles, for example, can transport pests inadvertently on tires or in soil that might cling to vehicles from infested areas. Household effects might contain items or pests that pose a risk when moving between regions. Seedlings of citrus trees are particularly important to regulate because they are a direct source of new citrus plants that may be affected by pests. In contrast, gardenia plants, while they may have their own pest issues, are not directly related to citrus pests and therefore do not fall under the same exterior quarantine regulations.
