Case Study Problem: Mitigating a Spodoptera Outbreak

Part 1 Instructions:
Read the following facts on Spodoptera. Attempt to answer the questions on mitigation efforts by synthesizing what you have learned about preparedness, response, recovery, and mitigation.

Fact 1:  Spodoptera has been identified as one of several potential plant diseases that an agroterrorist might attempt to use to cause an intentional plant biosecurity outbreak in our country. They are eminently portable. Various Spodoptera species are regularly intercepted on the clothing of international travelers on in international shipments.

Fact 2: Spodoptera feed on a wide range of agriculturally important crops throughout the entire year and are extremely resistant to pesticides. According to the European and Mediterranean Plant Protection Organization, "Spodoptera litura is an extremely serious pest, the larvae of which can defoliate many economically important crops." Data Sheet on Quarantine Pests: Spodoptera littoralis and Spodoptera litura

Fact 3: Spodoptera is on the EPPO‘s “A1“ list of “Pest Recommended for Regulation as Quarantine Pests.” The area represented by EPPO and the United States are virtually the only global areas where the pest has not yet established a stronghold, with Africa, the Middle East, Central and South America, and Mexico having a history of combatting Spodoptera.

Synthesis Questions:

  1. How do the four phases of plant biosecurity management apply to the threat of a Spodoptera outbreak?

  2. Spodoptera mitigation activities will occur in two “stages.” What are they?
    Hint

  3. Who is responsible for Spodoptera mitigation efforts?
    Hint

  4. As a front-line Extension professional, what actions will you take to help producers mitigate the consequences of a Spodoptera outbreak?
    Hint

Part 2 Instructions:
Review the USDA action plan on Spodoptera to determine if you have answered the questions completely.
