Augmentative Biological Control in Protected Culture and Greenhouses


Open fields, high tunnels, and greenhouses can have very different pest pressures. In open fields, releases of commercially available natural enemies may not be effective as they can easily escape. However, releases can be quite effective in greenhouses as the biological control agents are contained. High tunnels, which are a hybrid of both, may also be well suited to natural enemy release. This presentation will cover the research on releases in high tunnels and greenhouses and upcoming research.
