Trichogramma pretiosum

Description

Use Trichogramma spp., a moth egg parasite that prevents caterpillars (Lepidoptera) from emerging by laying their eggs in the moth eggs, killing them.

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 or crop type:

• T. minutum – East of the Rockies.
• T. platneri – West of the Rockies
• T. pretiosum – General Parasitoid
• T. brassicae – Low Lying Crops

NOTE: Emergence holes are evident under significant magnification after Trichogramma have hatched.
