• Parasitize larger and winged aphids
• Important contribution to biological control of small aphids through host feeding, also on aphids which they do not parasitize

• Do not swarm out, so that they stay locally active

How does biological control with Aphelinus-System work?

• Female parasitic wasp puncture the host and lay an egg
• 1 parasitic wasp parasitizes 5 to 10 aphids a day
