Use for
Pests
Armoured scales (Diaspididae), especially California red scale (Aonidiella aurantii) and oleander scale (Aspidiotus nerii). It also has an effect on San José scale (Comstockaspis perniciosa).
How it works
Mode of action
The female wasp deposits one or more eggs under the scale cover of armoured scales. Upon hatching the larva proceeds to feed on the scale. After reaching adulthood, the adult wasp chews a small round hole in the scale cover and leaves. Aphytis melinus also exerts control by predation on its host (host feeding).
Visual effect
In parasitized scales a round hole on the back is visible after the emergence of the adult wasp.

Directions for use
Application
Divide each cup into 11 release points. Use the lid, the 8 strips of green paper, the cotton wool on the bottom and the cup itself. Distribute evenly across the field. Release more doses in the areas of the field where the scales are present. Release early in the morning or late in the afternoon.
Dosage
The dosage of Aphytis depends on climate, crop and armoured scale density and should always be adjusted to the particular situation. Start introduction as soon as the first armoured scales are detected in the crop. Introduction rates in outdoor crops typically range from 20,000-50,000 per ha/release. Releases should be repeated monthly for 4 to 10 times per year. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
