Trichogramma are minute wasps that act as egg parasites. They lay their eggs in the eggs of various pests. After hatching, Trichogramma larvae feed on the eggs of the pest and thus destroy the pest, before they cause any damage to the crop. Trichogramma is effective in controlling pests of sugarcane, cotton, rice, vegetables and fruits. A number of countries are producing trichogramma biopesticide on a large-scale, although in India they are being produced only on a small scale, and that too by the cooperatives, state agriculture departments, IPM centres and agricultural universities.
