Aphidius colemani is a parasitic wasp used in the biological controlling of aphids. Adults are tiny black wasps. All other life stages will develop inside the host.
Life cycle and relative effectiveness
An adult pierce the aphid and leaves an egg inside. The parasitized aphid swells up and turns into a leather-like grey or brown coloured mummy. As an adult, the parasitic wasp leaves the mummy. Within two weeks after introduction the parasitic wasps the first mummies emerge in the crop. Aphidius colemani is highly effective in the early stage of the aphid infestation. Due to higher temperatures (above 30°C) the performance of this parasitic wasp decreases considerably.
Application and dose
The materials should be plotted on the rockwool, remaining a few days rest.
Storage and handling
Aphidius colemani supplied in bottles (100 ml.), containing 1.000 parasitic wasp. Keep the bottles horizontally, in darkness, at a temperature between 8°C – 10°C. Maximum storage time of two days
