Erviline - Aphidius ervi - Vial 30 mL - 250 Count

Erviline product contains Aphidius ervi, a tiny braconid wasp that stings and parasitizes large species of aphid.  In an optimum condition a female can parasitize about 300 aphids in her lifetime. Parasitism is manifested by immobility and swelling of the aphid, which eventually turns into a light-brown mummy from which a new parasitoid emerges by piercing around, regular opening. Erviline is a complementary product for Aphiline, together these products parasitize a wide range of aphid pests.

How It Works

• The female predatory wasp lays an egg in the aphid. The egg hatches within 2-3 days and the larva feeds on the aphid leaving a parasitized mummy on the plant.
• The Aphidius ervi life cycle takes approximately 14 days at 25°C / 77°F or 19 days at 21°C / 70°F.
• Where established aphid colonies are already present, the product may be used curatively at a higher rate, generally by releasing the predatory wasps immediately adjacent to the aphid colonies.
• If no previous releases of Aphidius ervi have been made, aphid pest populations can grow rapidly and supplemental control methods may be needed.

Available delivery systems

• 125ml vial containing purified mummies in sufficient quantity to yield 250 adults of Aphidius ervi.
• No carrier material is used, so emerging adults are able to fully expand their wings and can quickly reach the available food source without becoming exhausted by crawling through a shifting mass of bran or vermiculite particles.
