The parasitoid is sold commercially for biological control of whitefly, an insect pest of tomato and other greenhouse crops. Encarsia formosa has been used as a natural pesticide to control whitefly populations in greenhouses since the 1920s. Use of the insect fell out of fashion due to the increased prevalence of chemical pesticides and was ...
Many parasitoid wasps are considered beneficial to humans because they naturally control agricultural pests. Some are applied commercially in biological pest control, starting in the 1920s with Encarsia formosa to control whitefly in greenhouses. Historically, parasitoidism in wasps influenced the thinking of Charles Darwin. [3]
Periodic releases of the parasitoidal wasp, Encarsia formosa, are used to control greenhouse whitefly, [25] while the predatory mite Phytoseiulus persimilis is used for control of the two-spotted spider mite. [26] The egg parasite Trichogramma is frequently released inundatively to control harmful moths. New way for inundative releases are now ...
