Five groups will explore the MedFly problem and four groups will explore the RIFL problem. Each group will represent a different "interest group" and investigate a different perspective of the problem. For both problems, the following 4 interest groups will be represented by different groups.

Each can be guided by a specific question(s):

A. California Dept. of Agriculture (CDFA) - What's the exotic pest problem?
    and What are the possible control measures we can recommend?
B. Public interests - What are the dangers of the control measures to humans?
C. Agricultural interests - What are the dangers or costs of not controlling
    the problem?
D. Environmentalists - What are the dangers of control measures to
    natural biodiversity?

For the MedFly problem, an additional interest group will be represented:

E. Politicians - What are the consequences of arguing
    1) that the MedFly is endemic but kept at very low levels in refuge populations or
    2) that the MedFly is "eradicated"?
   (which interest groups will support each position and which will oppose your
              position?)

Evaluation of performance:
    All members of each group will turn in a one page (single spaced or 2 page double spaced, not counting references) report on their perspective. This will provide a 30 pt individual score.

    On Fri. and Mon., April 23 & 26, the groups will present oral reports as a town hall meeting. To prepare, each group will review the papers written by the group members and decide on the best information to present during a 5 min. public presentation (to the class). Each group will select a speaker to present the information to the class in a panel discussion format. The class-members not on presenting teams will evaluate the presentations, as will I, using specific criteria to be given in another handout. This will provide a group score of 30 pts.

Background (see www.cdfs.ca.gov):
    MedFly (Ceratitis capitata) This is an exotic pest, originally from Mediterranean regions of Europe, now introduced into California perhaps from Hawaii, Mexico, or Guatemala. It feeds on many kinds of soft fruits, such as citrus. It has been found in small populations throughout northern and southern parts of California, including LA, Orange, and San Diego Counties. Mating behavior is complex and males are attracted to receptive females by pheromones. This species will be used as a model for understanding mating behavior and how pheromones can be used for pest management. Control measures include chemical controls, bait attractants, and sterile insect releases.

     Red Imported Fire Ant (Solenopsis invicta) This is an exotic pest that has become widespread in Texas over the last 10 yr. or so where their presence has altered the native flora and fauna. Like most ants, it is a social species, with many reproductive queens in a nest. Their sting is quite painful and they tend to swarm over an animal before beginning to sting. They nest in relatively moist habitats. This organism will be used as a model for studying social behavior. Control measures include a variety of chemical controls.

Criteria for evaluating case study position papers, developed by consensus of class.
(Total value = 30 pts)

Position papers should include the following.

A. Statement of the pest insect problem. [15% = 4 pts]
B. Explain 2-3 control alternatives. [30% = 9 pts]
C. Present logical and scientifically justified arguments supporting or
    opposing the alternative control measures. [40% = 12 pts]
D. Present citations (references) to your sources of information (at least 5).
    [15% = 5 pts]
