Erviline

Aphidius ervi

Erviline biological control agent contains the Braconid wasp, Aphidius ervi. It stings and parasitizes larger aphids, such as the foxglove aphid, Aulacorthum solani, and the potato aphid, Macrosiphum euphorbiae, as well as several other aphid species.

Target Pests

• Aphids

Key Features

• Provides preventive control of large aphids.
• Not light sensitive – no diapause stage.
• Adults begin to emerge in transit, so they are ready for release.
• Ventilation and food source available in packaging to help ensure adult survival.
• Packaging allows growers to see the product clearly and judge its quality and purity.

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.
• Erviline can also be used in any crop where Macrosiphum euphorbiae is the principal pest aphid.

Delivery System

• 25ml (4oz) vial containing purified mummies in sufficient quantity to yield 250 adults of Aphidius ervi.
