Aphid parasitoid wasp for green peach aphid
Green peach aphid is one of the three hosts Koppert sells this wasp for. Start soon after planting and release at least three times: the first mummies appear 10–14 days after the first release, and that — not fewer aphids — is the first sign it is working. Where colonies are already established, the wasp cannot catch up on its own; add the gall midge on the hot spots.
Before you order
Released preventively under glass from soon after planting; for the small aphids — green peach, melon and tobacco aphid. How it works, how to tell it has established and the supplier list are on the full Aphidius colemani profile.
