TARGET PESTS: Most Aphids. Potato Aphid (Macrosiphum euporbiae), Greenhouse Potato Aphid (Aulacorthum solani), Pea Aphid (Acyrthosiphon pisum), Green Peach Aphid.
DESCRIPTION: A parasitic wasp that attacks several species of aphids. Used mostly in greenhouses producing vegetables and ornamentals. Adult wasps are black 4-5 mm long. Adult females lay eggs from their abdomen by quickly curling their abdomen and puncturing an aphid simultaneously with its ovipositor. The egg, once inside the aphid, will hatch into a larva and consume the aphid. The larvae, when fully grown, will cut a slit in the carcass and attach it to a fixed object. The larvae then pupates (spins a cocoon) inside the dead aphid. The mummified aphid swells into a characteristic round, golden brown mummy. The emerging adult will cut a symmetrical hole at the bottom end
to escape from the mummified aphid.
After injecting the aphid with an egg, it takes about a week for the mummy to form and then another week for the adult to appear. Each female can lay more than 100 eggs.
PRODUCT INFORMATION: Aphidius ervi are shipped in containers of 250 adults.
RELEASE RATES: Release wasps as soon as possible between plants in the morning or evening in mild/cool temperatures
and low light levels.
LIFESPAN: Egg to adult: about 2 weeks, adults live for about 14 days.
STRATEGIC CONSIDERATIONS: Apply this parasite before a colony of aphids are large. For best results: Always be proactive, not reactive. Aphids reproduce faster than the A. ervi.
