Trichogramma -
Prevent worm pests before plants become damaged with these moth egg parasites.
Preferred food:
The eggs of more than 200 pests, including borers, webworms, loopers, leafworms,
fruitworms, cutworms, bollworms, and armyworms (except beet armyworms). The wasps
lay their eggs in the pest eggs, killing them. The adult wasps emerge anywhere
from 7 to 75 days, depending on temperature and moisture.
Attacks eggs of over 200 varieties of insects, almost all moth and butterfly
eggs that hatch into worm pests. Should be used in 3 separate releases and 3
vials will do 500 square feet, or 10 vials per acre. The best time to release
is at the first sign of moths and it will reduce the number of eggs which will
reduce pest insects. Specify your preferred shipping date and it should be
before hot weather in your area. Releases should be completed by mid June.
