Types of Biological Control and Implementation Conservation biological control (no releases, limit pesticide usage and protect resources used by established natural enemies)

Types of Biological Control and Implementation Classical biological control (usually targeted at an alien pest and self-sustaining)

16 Introduce natural enemies Natural Enemy Releases 14 EIL 12 10 (years) Time 8 6 Introduction of pest 4 2 10 5 0

Types of Biological Control and Implementation Inoculative biological control (usually not self-sustaining, releases at beginning of the cycle)

Begin cycle Inoculative Releases cycle End EIL 8 (Months) 7 Time Introduce natural enemies 6 5 4 Begin cycle 1 0.5 0

Types of Biological Control and Implementation Inundative biological control
