Important Factors to the Evolution of Local Adaptation

• Natural enemy host range

• Relative life span of natural enemy and pest

• Relative migration rates of n.e. and pest

Challenging Questions

• Do introductions of natural enemies impose bottlenecks?

• Is reduced genetic variation associated with low fitness?

Challenging Questions

• What is the risks of pests evolving resistance to natural enemies?

• If pests evolve resistance, will Natural enemies evolve mechanisms to overcome pest resistance?
