Encarsia formosa Whitefly Parasite

Control Greenhouse Whitefly with this non-biting parasitoid wasp. Encarsia formosa parasitizes Greenhouse Whitefly (Trialeurodes vaporariorum) and provides limited control of Sweet Potato Whitefly (Bemisia tabaci). Encarsia Formosa is not recommended for control of other species of whitefly. Release Encarsia Formosa prior to or at the first sign of whitefly infestation. When used preventatively in an Integrated Pest Management program, Encarsia formosa can greatly reduce labor and control costs due to their relatively low cost and their mode of action.
