Product details
Mode of action
Adult hoverflies emerge from the pupae and deposit their eggs in the aphid colonies. The young larvae start feeding on the aphids.
Visual effect
Aphids are consumed entirely, only skin remains. Dark excrements (meconium) on the leaves is an indicator of hoverfly larvae activity.

Directions for use
Dosage
The dosage of Syrphidend depends on climate, crop and aphid density and should always be adjusted to the particular situation. Start introduction preventatively or as soon as the first aphids are detected in the crop. Introduction rates typically range from 100-600 pupae per ha/release. Releases should be repeated a number of times. Consult a Koppert advisor or recognized distributor for advice on the best strategy for your situation.

Frequently Asked Questions
-
What is Syrphidend used for?
Syrphidend is used to control all aphid species.
-
What does Episyrphus balteatus look like?
Eggs are oval, 1 mm long and white/grey colored. The larvae are up to 11 mm long, transparent/beige without legs. Pupae are beige/brown in color, and droplet shaped. The adults are 10-13 mm long and have a dark yellow face and golden abdomen with black stripes.
-
What is the life cycle of Episyrphus balteatus?
Eggs are laid close to aphid colonies. After hatching, E. balteatus goes through 3 larval stages, followed by a pupal stage. Adults emerge from the pupa. Total egg-adult development takes around 17 days at 22ºC.
-
What is the fecundity of Episyrphus balteatus?
Females can lay around 2000 eggs during their lifespan.
-
How many aphids can Episyrphus balteatus larvae consume?
During its development, each larva of E. balteatus can consume around 1000 aphids, depending on aphid species and age.
-
On which crops can Syrphidend be used?
Syrphidend can be used in both greenhouse and outdoor crops, whenever aphids are present. Adult hoverflies feed on pollen and nectar, and their activity is enhanced when flower resources are available.
-
Will ants influence the effect of Syrphidend?
Ants may remove pupae of Syrphidend and carry them to their nest. Avoid placing the boxes directly near ant visited aphid colonies.
-
I see unhatched pupae, are those dead?
Syrphidend consists of pupae which will hatch into adult hoverflies. At arrival, most pupae will not be hatched. Some pupae may not hatch due to natural mortality. This is already considered in the number of pupae included in the box.
-
I see adult hoverflies moving but they don’t fly, is this normal?
Adult Episyrphus balteatus do not fly immediately after hatching, they require some time to fully extend their wings and being able to fly.
