Trichogramma Japonicum
Trichogramma japonicum is a tiny parasitic wasp, primarily used in the biological control of rice pests. It parasitizes the eggs of various lepidopteran pests, particularly the rice borer (Scirpophaga incertulas). This species is particularly effective in paddy fields, where it plays a crucial role in managing rice pests. T. japonicum has a narrow host range, favoring pests found in rice-growing environments. It thrives in humid, warm conditions typical of rice fields and is more commonly utilized in regions with rice cultivation. Its parasitism helps reduce the reliance on chemical pesticides, promoting sustainable farming practices.
Targets
Rice Stem Borers
(Scirpophaga incertulas, Chilo suppressalis)
Rice Leaf Folders
(Cnaphalocrocis medinalis)
Diamondback Moths
(Plutella xylostella)
Handling Guidelines
Hang Trichogramma japonicum cards evenly across the field by attaching them to plant foliage. Avoid placing the cards on the ground or in direct sunlight, as this can harm the wasps.
Handle with clean hands and maintain proper hygiene to preserve their viability during release.
Application
To apply Trichogramma japonicum, begin by monitoring pest activity using pheromone traps or light traps. Release should start as soon as adult pests are detected in the field. Use Trichogramma egg cards, hanging 18–30 cards per acre to achieve effective control. For best results, make a second release 7–10 days later, depending on the level of pest infestation—releasing twice in a row can significantly improve effectiveness. Avoid using chemical pesticides immediately before or after releasing Trichogramma, as this may harm the beneficial insects and reduce their performance.Storage
Store Trichogramma japonicum in its original packaging at a cool temperature between 4°C and 8°C (39°F – 46°F) for best results. Keep the packaging placed horizontally in a cool, dark area to protect the wasps. For best effectiveness, use the product within 7 days of receiving it, as the tiny wasps have a limited lifespan outside of optimal conditions.
