Trichogramma brassicae is especially useful for controlling moth (Lepidoptera) populations on cole crops. Use T. brassicae in cooler climates with low-lying plants affected by caterpillar and/or borer damage.
Timing the release is important – if you release too early there aren't enough pest eggs for the wasps to parasitize - too late means that the pest eggs have hatched and you have a new problem - caterpillar pests.
Biology & Life Cycle: Trichogramma wasps lay their eggs inside the pest eggs, stopping development. The larvae feed on the egg and then emerge as adults. The larvae take 10 days to develop within the pest moth egg, which turns brown or black as the larvae pupate. The adult wasps live anywhere from 7 to 14 days, depending on temperature and moisture and the female Trichogramma will parasitize up to 300 pest moth eggs. Eggs on cards usually hatch within 2-5 days.
Choose the correct variety for your region, crop type and dispersal preference:
This Product Controls These Pests or Diseases: Trichogramma parasitize the eggs of more than 200 pests including Borers, Webworms, loopers, leafworms, fruitworms, cutworms, bollworms, and armyworms (except beet armyworms).
Release Rates:
Bulk Eggs
- 1-2 per sq. ft.
- 50,000 - 100,000 per acre.
- Bulk eggs are shipped without a medium. Use Hanging Release boxes to distribute.
Release immediately upon receipt. Release Trichogramma at first flight of moths and every 7-10 days thereafter until infestation subsides. It is best to release in the early morning or evening out of direct sunlight, below plant tops or in trees where moths have been seen.
Using traps to monitor for adults and visual inspection of foliage to monitor for moth eggs will help determine the best time to release Trichogramma.
