Aphidius colemani, which are normally shipped as ready-to-emerge mummies (expect to see some hatched adults on arrival), seem to be the product of choice when melon or cotton aphids (Aphis gossypii) are present as these are typically the aphid species on which they are reared. But it will also attack the green peach aphid (Myzus persicae), the tobacco aphid (Myzus nicotianae) and the bird cherry-oat aphid (Rhopalosiphum padi) commonly used on banker plants.

Introduction:  Sprinkle mummies on rock wool or in Distribution Boxes in small heaps (not thicker than 2 cm!) and leave it there for at least one week.

Environmental conditions:  Not active at high temperatures (above 30°C).

Storage and handling

  • storage after receipt: 1-2 days
  • storage temperature: 8-10°C/47-50°F
  • in the dark


  • Adults: size 3-5 mm, black
  • Other stages: develop inside host

Mode of action:  Female adult parasitic wasp parasitizes the aphid.

Visual effect:  Parasitized aphid swells and hardens into a leathery, grey or brown coloured mummy. The adult parasite emerges through a round hole at the rear of the mummy. The first mummies can be seen in the crop approximately 2 weeks after the first introduction.

Advisories:  Yellow sticky traps should be removed prior to releasing these mini-wasps. To monitor for thrips, use blue traps. If yellow traps must be used for whiteflies, etc., hang them for only two days per week. Watch for ants which, if present, should be controlled. They will defend aphids from predators and parasites to protect their honeydew food. Use barrier, exclusion products or boric acid products to control the ants. If your planting doesn’t have any ants, check to be sure that the honeydew isn’t too heavy. This may prove to be a hindrance to the parasitoids’ performance; they may spend too much time cleaning themselves.

Important!  The introduction rates of this product should be adjusted to the mode of action of the product and the results that can be expected in the crop where the product is applied. Your local consultant will be able to advise you further.
