How does biological control with Aphidius-System work?

Females lay hundreds of eggs during the first 4 days of their adult life The parasitic wasps detect alarm signals from an affected plant and the smell of honeydew secreted by the host. This allows them to locate aphid hot spots from a long distance They can parasitize up to 300 aphids The parasitic wasps parasitize both adults and nymphs Parasitized aphids change into golden brown mummies Parasitic wasps can cause a panic reaction, due to which the aphids fall onto the ground and die
