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. See our Whitefly Control page for alternative beneficial insects and control options.

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. Combine whitefly parasite releases with Yellow Sticky Traps, Green Lacewing and Biorational Controls, like Beauveria bassiana, for consistent monitoring and continued control.

Appearance: Adult female Encarsia formosa are black with a yellow abdomen, opalescent wings and measure approximately 0.6 mm. Males are present in much lower numbers than females and are darker in color.

Life Cycle: Adult Encarsia formosa emerge from the parasitized pupae (whitefly scale) over a period of 1-2 weeks. They actively lay eggs in 2nd-4th nymph stages of whiteflies from which Encarsia formosa larvae hatch out. The larvae kill developing whiteflies for roughly three weeks until reaching adulthood, which lasts up to month. The parasitized whitefly pupae will turn black or brown. Adult Encarsia formosa continue to lay eggs and reproduce.

Optimal Conditions: Encarsia formosa do best in temperatures of 68° – 77°F and relative humidity <70%. Since these are optimal conditions, Encarsia formosa remain effective outside of those temperature and humidity ranges; however, lower temperatures can inhibit reproduction and maturation.

Encarsia formosa can be used in conjunction with other beneficial predators and parasites including Green Lacewing, Delphastus catalinae and/or Eretmocerus eremicus.
