Encarsia is a parasitic wasp used worldwide for the biological control of Greenhouse Whitefly (Trialeurodes vaporariorum) and Silverleaf Whitefly (Bemisia tabaci) on vegetables and ornamentals.

Encarsia can be introduced into all crops attacked by Greenhouse Whitefly including tomatoes, cucumbers, eggplants, and a wide range of nursery, ornamental and broad-acre crops.

Encarsia should be used in conjunction with Eretmocerus warrae or Eretmocerus hayati, especially in hotter conditions. Eretmocerus are also more tolerant of some pesticides. In tomato/eggplant crops, Nesidiocoris tenuis should also be used with whitefly parasites for best results.

Encarsia is most effective in greenhouses but can establish outdoors depending on climatic conditions and pest numbers.
