CDFA Pest Prevention Plant Regulation Practice Exam

What is the area under quarantine in California for the cherry fruit fly?

1. The county of Sacramento only

2. all counties north of San Francisco

3. the county of Siskiyou only

4. portions of the counties of Siskiyou, Shasta, Trinity, and Humboldt

The correct answer is: portions of the counties of Siskiyou, Shasta, Trinity, and Humboldt

The area under quarantine for the cherry fruit fly in California includes portions of the counties of Siskiyou, Shasta, Trinity, and Humboldt because these areas are known to be affected by outbreaks of this pest. The cherry fruit fly can have a significant impact on cherry crops, leading to strict quarantine measures to prevent its spread and to protect agricultural interests. Due to the pest's lifecycle and its potential to inflict damage on cherry production, specific regions are monitored, and quarantines are established based on environmental conditions and historical data regarding the presence of the fruit fly. This targeted approach allows pest control and agricultural authorities to effectively manage and contain the pest in specific areas rather than imposing blanket restrictions across larger regions that may not be affected. In contrast, options that mention only one county or areas that do not consider the spread of the pest are incorrect given the broader surveillance and management goals of California's pest prevention strategies. The correct understanding of the quarantine reflects the necessity for localized intervention in pest management practices.
