Parasitic wasp against multiple aphid species

What is Matricariae-System?

• The parasitic wasp Aphidius matricariae against no less than 40 aphid species
• Excellent biological control agent against e.g. the green peach aphid Myzus persicae and other closely related species such as the tobacco peach aphid Myzus persicae var. nicotianae 

What are the benefits of Matricariae-System?

• Faster and more extensive parasitisation of aphids than with other Aphidius species
• Excellent detection of aphid colonies even at low prey density
• Contribution to the disruption of the Foxglove aphid Aulacorthum solani
• Better adapted to low temperatures
• Less susceptible to hyperparasites 

How does biocontrol control with Matricariae-System work?

• They parasitize adult aphids and nymphs
• Females lay about 100 eggs and attack up to 300 aphids
• They lay most eggs during the first 4 days
• Parasitized aphids change into golden brown mummies
• The parasitic wasps can cause a panic reaction, due to which the aphids fall onto the ground and die 

In which crops can you introduce Matricariae-System?

In crops where aphids present a challenge such as:

• Organically grown peppers
• Organically grown strawberries
• Ornamental crops
• Herbs
