Syrphidend Beneficial Hoverfly

Scientific name: Episyrphus balteatus.

The marmalade hoverfly, of the Syrphidae family, is widespread throughout the Palaearctic region and can be found in various habitats throughout the year visiting flowers for pollen and nectar. Episyrphus balteatus is among the very few species of flies capable of crushing pollen grains and feeding on them. They often form dense migratory swarms and is one of the migrating hoverflies. Adult E. balteatus, while not as efficient as honey bees, are significant and abundant pollinators. The larva is terrestrial and feeds on aphids. For this reason, E. balteatus is considered one of the main natural enemies of cereal aphids. In the wild, an E. balteatus larva can consume up to about 400 aphids before pupating.

Use for:

• Biological control of all species and stages aphids
  
• Disperses well and finds aphid hotspots.

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.

Visually, aphids are consumed entirely, only skin remains. Dark excrements (meconium) on the leaves is an indicator of hoverfly larvae activity.

• Carefully open the perforated lid of the carboard box.
• Hang the open box vertically on the plants, preferably close to flowers.
• Protect from direct sunlight or rain.

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 to 600 pupae per ha/release. Releases should be repeated a number of times.

Environmental conditions:

• S yrphidend is most effective between 15°C and 23°C.
• High humidity is favourable for larval development and hatching of pupae.
• Adult hoverflies feed on pollen and nectar. Ensure flowering plants are present for optimal establishment.
• For effective control of aphids combine with other predators and/or parasitoids.
