Trichogramma wasps are tiny parasites that attack the eggs of over 200 species of moths and caterpillars. They are extremely small - 4 or 5 will fit on the head of a pin. Trichogramma lays its eggs inside the eggs of moths preventing the moth egg from hatching into a caterpillar. This prevents the damage caused by the feeding caterpillars, and also breaks the life cycle of the pest, effectively preventing the pest from reproducing. In some species of moth up to 5 parasite eggs may be laid in each moth egg. As the parasite develops within the egg, it turns black, and after about 10 days, an adult Trichogramma emerges. Adult Trichogramma can live up to 14 days after emergence.
Some of the common pests Trichogramma combat are: Cabbageworm, Tomato Hornworm, Corn Earworm, Codling Moth, Cutworm, Armyworm, Webworm, Cabbage Looper, Corn Borer, Fruitworms, and Cane Borers. Some of the popular hosts of T. brassicae mini-wasps are the eggs of: the Gypsy moth, codling moth, diamondback moth, Oriental fruit moth, tomato pinworms, cabbage loopers, imported cabbage worms, tent caterpillars, even the grossly damaging tobacco/tomato hornworms.
