CDFA Pest Prevention Plant Regulation Practice Exam

Where does the woolly white fly infests in the state of California?

1. The same area as citrus white fly

2. A portion of the county of San Diego

3. A portion of the county of Fresno

4. The entire county of San Joaquin

The correct answer is: A portion of the county of San Diego

The correct answer indicates that the woolly white fly primarily infests a portion of the county of San Diego in California. This pest has been particularly reported in specific geographic areas, which can greatly influence pest control measures and agricultural practices within those regions. Recognizing that the infestation is localized helps in focusing pest management efforts effectively and understanding the distribution of this pest species. The other options propose broader or different regions that are either inaccurate or suggest a lack of specificity. For instance, stating that it infests the same area as the citrus white fly does not reflect the unique pest distribution; while there may be some overlap, it fails to pinpoint the woolly white fly's specific prevalence. Similarly, claiming it affects the county of Fresno or covers the entire county of San Joaquin misrepresents the actual localized nature of this pest's impact in California. Understanding where pests exist allows for more effective monitoring and control efforts tailored to those specific areas.
