SARE-funded researchers at Cornell University found that with a combination of controls, greenhouse and high tunnel pests could be managed effectively and, in some cases, eradicated.

Highlights of 23 New York case studies include the development of an effective combination of parasitic wasps (Aphidius colemani and Aphidius ervi) to eradicate an aphid infestation on winter greens and peppers. And predatory mites (Amblyeius cucumeris) used in conjunction with minute pirate bugs (Orius insidiosus) helped eradicate thrips on cucumbers. Researchers also found that the two-spotted spider mite was effectively managed by applying a parasitic mite (Phytoseiulus persimilis) on eggplant and strawberries. The Nile Delta wasp (Encarsia formosa) helped manage, and in some instances, even eradicate whiteflies on tomatoes.

The fact sheet includes an introduction to biological control, along with colorful photos that can be used to identify pests and their associated crop damage. It also provides specific how-to information on scouting for pests along with detailed release information, including optimal temperature, quantity of natural enemies and timing of release relative to pest populations. Management strategies for control agents, such as predatory mites and parasitic wasps, and a supply list for obtaining biological control agents are also found in the fact sheet.
