Aphidius matricariae

Identification

Aphidius matricariae is a parasitic wasps specializing in the control of almost 40 species of aphids. At Anatis Bioprotection, this species is used to control the Cannabis aphid (Phorodon cannabis) in hemp and cannabis crops.

The adult is black with brown legs. This parasitoid wasp has long antennae and is approximately 2-3 mm long. After mating, the female lays her eggs inside juvenil or adult aphids. Aphidius matricariae larvae develops and feeds on the internal organs of the aphid. After 7 days, the aphid becomes immobile, swells and turn beige. We call this stage "mummy". A new adult emerges from the parasitized aphid after a few days.

Aphids are pests that reproduce very quickly. It is therefore advised to use Aphidius matricariae in prevention with the introduction of Banker plants or as soon as the first aphids are detected. In summer,Aphidius wasps can be used with the Aphid predatory midge Aphidoletes aphidimyza.Control is achieved are parasitized.
