Encarsia formosa Loose 100,000 Pupae is a biological control solution designed to help manage greenhouse whitefly populations in protected horticultural crops.

Encarsia formosa is a tiny parasitic wasp that targets greenhouse whitefly (Trialeurodes vaporariorum). Female wasps lay their eggs inside whitefly nymphs, where the developing parasitoids feed on their hosts. Parasitised greenhouse whitefly pupae typically turn black, providing a useful indication of biological control activity.

Supplied as 100,000 loose pupae, this product is suitable for professional growers looking to incorporate natural pest control into their Integrated Pest Management (IPM) programmes.

Encarsia formosa is particularly effective when introduced preventatively or at the first signs of whitefly activity. It is widely used in protected crops, including tomatoes, cucumbers and ornamental plants, helping growers reduce their reliance on conventional insecticides.

As part of a wider biological control strategy, Encarsia formosa supports sustainable crop protection and helps maintain healthy, productive growing environments.
