Ervi System
What is Ervi-System?
- The biological control agent Aphidius ervi
- Most frequently used parasitic wasp to control large aphids
- Efficient against large aphid species such as the potato aphid Macrosiphum euphorbiae and the buttercup aphid Aulacorthum solani
- Very good search behaviour that allows them to detect and parasitize incipient aphid hot spots at low prey density
- Can distinguish parasitized from non-parasitized aphids
- Develops and spreads fast in the crop
- Adapted to low temperatures
- 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 hundreds of 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
- Ornamental crops such as chrysanthemum and gerbera
- Vegetable crops such as tomato, eggplant and pepper
- Soft fruit such as strawberry and raspberry
- Tree nursery
