How to release Aphidius colemani?

  • For best results, application should be during mild temperatures (early morning or late afternoon).
  • Remove the container lid and place the container near an aphid hotspot. You may also use bioboxes hung on the plant to release.
  • Make sure the mummies remain dry and are not disturbed for 2-3 days
  • Don’t sprinkle the mummies directly on to the plant. They can fall into the soil and get wet which will decrease the hatchability rate
  • Avoid washing or debranching the plants after release.

Can you store Aphidius colemani?

We recommend releasing the predators immediately upon arrival.

If storage is necessary aphidius colemani can be stored for 1 day in a cool (8-10°C) dark environment. Avoid contact with direct sunlight.

How to promote establishment?

Temp/humidity: The wasps’ activity is optimal between temperatures of 20-30°C. Colder temperatures (below 15C) can cause the parasitoid to become inactive.

Supplementary Food: Aphid Banker Plant, 10% honey solution

If ants are present at the aphid hot spots, they must be destroyed. Ants encourage honeydew secretion by the aphids, transfer them from one place to another and protect them by actively interfering with the parasitoid.

How to spot A.colemani after releasing?

Aphidius colemani are tiny and dark coloured wasps that do not sting. Marking the release areas and look for parasitized aphids in those areas. The mummies should appear two weeks after the release.

How long till you see results and how often should you be reordering?

The mummies should appear two-three weeks after the release. They will produce the next generation of the parasitoid. If aphid infestation is high release should be made weekly 2-3 times to create overlapping generations of the parasitoid.
