Interpretive Summary: Encarsia formosa Gahan is a small parasitic wasp that is used worldwide for the control of various whitefly pests. Due to both its high reproductive capacity and predation behavior, it has proven to be one of the most effective whitefly natural enemies. Encarsia formosa was the first parasitic wasp species made available commercially, and is used primarily for pest control on economically important vegetable and ornamental crops grown under greenhouse conditions. In this article we summarize the life history of E. formosa, some potential target pests, its historical and current usage, and strategies for its effective release.

Technical Abstract: Biological control of whitefly pests on economically important vegetable and ornamental crops grown under greenhouse conditions has relied heavily on the use of parasitoid wasps. Globally, the aphelinid wasp Encarsia formosa Gahan has been one of the most widely utilized and successful species, demonstrating efficacy on more then 15 whitefly species. In this article we discuss key aspects of the biology of E. formosa, which has lead to its success as a biological control agent and provide details on methods for its use.
