Summary
Aphids can be regulated without or with fewer plant protection applications, thanks to natural enemies.
Practical recommendations
Indirect regulation with natural enemies
The following natural enemies are effective in regulating the stone fruit aphids, e.g., the black cherry aphid:
• Hoverflies: Larvae feed on aphids (Picture 2). Adults need to feed on nectar and pollen (Picture 4).
• Ladybug: Larvae and adults feed on aphids (Picture 6, 7). Adults of some ladybug species also need pollen.
• Parasitic wasps: Adults lay their eggs within the aphids. The aspect of the parasitised aphid (aphid mum-my) is typical for each parasitoid (Pictures 9, 10, 11). Adults feed on nectar.
• Lacewings: Larvae feed on aphids (Picture 14). Adults feed on nectar, pollen, and honeydew (Picture 16).
These natural enemies can be released early in the season (March/April) and/or promoted by implementing flower strips around and within the orchard.
