Description

Aphiline

Apheline (Aphelinus abdominalis) is a small wasp that will sting and parasitise young stages of aphids such as potato and rose aphids (Macrosiphum spp), Foxglove aphids (Aulacorthum solani , Strawberry aphid ( )and cannabis aphids. Aphelinus is known to live longer and lay eggs in longer period than other aphid parasitoids and, therefore, offers a good complimentary product for long-term aphid prevention for all crops especially that they do not have diapause and are not light sensitive.  Adults begin to emerge in transit, ready for immediate release. Ventilation and food source available in packaging ensure adults survive during transit.

Key Features

  • Prevents aphid populations from developing and reduces moderate populations to non-damaging levels.
  • Adults begin to emerge in transit, ready for immediate release.
  • Not light sensitive – no diapause stage.
  • Ventilation and food source available in packaging ensures adult survival in transit and storage.
  • Suitable for all greenhouse crops.

Target Pests

  • Adult Aphids

How It Works

  • The female wasp lays an egg within the aphid. The egg hatches within 2-3 days and the wasp larvae feeds on the aphid leaving a parasitized mummy on the plant.
  • The colemani life cycle takes 10 days at 25°C / 77°F or 14 days at 21°C / 70°F.
  • For preventive control, releases should be made weekly during periods when aphids are most likely to be found in the crop (usually in the spring or early summer).
  • Where aphid colonies are already present, Aphiline can be used curatively at a higher rate, generally by releasing the parasites immediately adjacent to colonies.
  • If no previous releases of Aphidius colemani have been made, aphid populations can grow rapidly and supplemental control methods may be needed.
  • Continue using Aphiline preventively so aphid populations do not become a recurring problem.
  • For advice on recommended release rates, consult the Bioline App.

Available delivery systems

  • 30mL (1oz) vial containing purified mummies in sufficient quantity to yield 500 or 1,000 Aphidius colemani
  • 250mL bottle containing 5,000 mummies.
  • 10 blister packs containing 100 mummies per blister to yield 1000 Aphidius colemani

Releasing

  • Release weekly at low rates before aphids begin to appear in the crop. If aphid colonies become established, make localized hotspot treatments or intervene at the economic threshold.
  • 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.
  • Make introductions early in the day or in late afternoon/early evening.
  • Repeat the introduction for two to three weeks

Instructions for Blister Pack use

  • Open the box in the greenhouse.
  • Remove sheet of blister packs from the envelope, and separate along perforations.
  • Bend the card forward slightly at the top of the blister, and pull the tab up.
  • Hang opened blister onto leaf petioles within crop so it is in a shaded position.

Storage and transport

  • Keep out of direct sunlight.
  • Transport and store at 6-10°C /43-50°F.
  • Use within 18 hours of receipt.
