Lower rates can be used for prophylactic treatments.

Storage
» Preferably use on day of receipt or within 1-2 days if stored in darkness at 10°C.

Technical Information
Trichogramma spp are tiny wasps less than 0.5mm long.  Adult females lay their eggs into the moth eggs.  These hatch and the larvae feed on the developing caterpillar within the egg.  The egg turns black as the parasite develops.  The life cycle takes 7-20 days depending on temperature.
