Aphidius colemani - Aphid ParasitoidAphidius.pdf

This species is not expected to parasitise the Giant Willow Aphid, or the Woolly Aphid. Aphidius is not effective against all aphid species, parasites are generally more host specific than predators. If unsure, we recommend using these wasps as part of the Aphid Pack, which is more likely to to give coverage of a wider range of aphid species. These wasps are 100% safe, they cannot sting.

Aphidius is known to be useful in indoor and outdoor crops such as, capsicum, cucumber, tomato, chrysanthemum and other ornamentals as part of an integrated pest management programme.

Aphidius is dispatched as “mummies packed in a Petri dish or vial, and sent either by fast post or courier (at the customer’s request).
0.2 Aphidius mummies per m2 as a PREVENTATIVE measure, preferably weekly
1-5 Aphidius mummies per m2 as a light to moderate CURATIVE measure, over several weeks

Heavier infestations of aphids can benefit from the simultaneous release of ladybird beetles and/or Orius , or may require initial chemical intervention (contact Bioforce to discuss). Because aphids breed very quickly, it is recommended that Aphidius is released at the first sign of aphid appearance. Aphidius can be hampered in summer from the presence of hyperparasites.

Aphidius is best suited to temperatures between 18°C and 30°C, and sustained temperatures over 30°C may reduce the effectiveness of this parasite.
Aphidius need the following handling and treatment:
  • On arrival, release Aphidius into the crop as soon as possible
  • Do not expose Aphidius to direct sunlight
  • DO NOT REFRIGERATE
  • Open the Petri dish or vial only once you are in the area in which Aphidius are to be released
  • Release Aphidius near an aphid ‘hot spot’, and then evenly distribute the mummies throughout the area requiring treatment
Aphidius will start parasitising aphids immediately on release, although you will not be able to confirm this until the parasitised aphid starts turning golden after 7 days (at 26°C) or longer if the average temperature is lower.

Before introducing Aphidius into your crop please check residual chemical affects and ensure you know chemical compatibilities of products that may be applied.

A list of compatible pesticides and withholding periods can be found in the publication ‘The Good Bug Book’ Second Edition (2002), Editor Richard Llewellyn.
