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.

Handling & Storage for Aphiline

Instructions for Aphiline Vials & Bottles

Release weekly at low rates as aphids begin to appear in the crop. If aphid colonies become established, make localized hotspot treatments or intervene at the economic threshold. If aphids are suspected of transmitting virus or populations are high, use a compatible chemical control before releasing Aphidius ervi. Do not spray between release of adults and mummy formation.
  • Open among plants in the greenhouse.
  • With the vial held horizontally at 45° angle, carefully remove the lid.
  • Release adult parasites evenly by gently tapping the opened vial while walking through the crop.
  • Recap the vial and store at greenhouse temperature until more adults have hatched.
  • Repeat the distribution of adults daily for 2-4 days.
  • Place the open vial containing the remaining mummies upright in the crop for 3-4 days.
  • Make introductions early in the day or in late afternoon/early evening.
