11.3.3 Questions and Tasks
1. What are the environmental concerns of pesticide use (groundwater contamina-
tion, deleterious effects on other populations, and so forth) and how could those
be included in the model?
2. What are the monetary costs of the modeled pesticide program? Are other meth-
ods of control more feasible (hand removal, temperature treatment, and other
strategies)?
