APHISCOUT

Mix of aphid parasitoids:
Appearance:

The product APHISCOUT is a mix of several aphid parasitoids: Aphidius colemani, Aphidius ervi, Aphelinus abdominalis, Praon volucre and Ephedrus cerasicola. The different species look different: some are black, others brown and / or yellow.

Mode of action: 

Adult female parasitoids slightly differ in their preference for aphids species for parasitisation. The product thus has a rather broad range of aphids that may be attacked. For all species it holds that after parasitisation aphids will  turn into round, firm mummies. Their colour will be different, depending on the species of parasitoid that has parasitised. Colour may be black, grey or brown. The type of colour of the mummies gives information on the aphid species that is present in the crop. Praon for instance can be recognized because of the pupa that will appear underneath the parasitized aphid. The other parasitoids pupate within the parasitized aphid. Mummies will appear around 2 weeks oafter introduction. Adult parasitoids of the new generation will hatch from the mummies through a round exit hole.
