Best Practices for Biocontrols, Part 3
- April 2021 Link Tiny parasitic wasps can provide effective biocontrol of some of your worst greenhouse pests.

The egg will hatch into a wasp larva, eating the aphid or whitefly nymph from the inside out, killing the nymph. They’ll pupate inside the host insect and emerge as a wasp that will then search for more hosts.
