The Trichogramma are a group of minute wasps (smaller than a needle’s eye) that lay their eggs in pest moth eggs, where the wasp offspring develop, kill the pest larvae, and produce new wasps.

We’re glad we did as we’ve recently got some not-so-favorable reports indicating that the jury is indeed still out for deliberations.

Mr. Fish was looking for production sources. With a motto of “Think First, Spray Last,” the Maine State Government is excited to have yet another tool at their disposal to help Maine growers manage pests without poisons — the lobsters are happy about it, too.
