Description

Aphiline

Diglyphus isaea is an ectoparasitic wasp that adults paralyze leafminer larvae of liriomyza species and lay her eggs next to it. The eggs quickly hatch and begin to feed. The paralyzed leafminer larvae discolour, move away from the tip of the mine and become flaccid and unresponsive, before eventually dying. Diglyphus is known to establish quickly after release in the greenhouse, making it suitable for controlling growing populations of leafminer.

Key Features

  • Adult Diglyphus paralyzes leafminer larvae with its sting and will host feed on them.

Target Pests

  • Leafminer

How It Works

  • Diglyphus adults paralyze pests and lay eggs next to paralyzed leafminer larvae, which quickly hatch and begin to feed.
  • Parasitized leafminer larvae move away from the mine and stop feeding, therefore the mine stops growing immediately.
  • The parasitoid pupates inside the leaf mine before hatching and continuing the cycle.
  • Development from egg to adult is 26-27 days at 15°C / 59°F and 10-11 days at 25°C / 77°F.
  • Activity decreases at low light levels.

Handling & Storage

Instructions for use

    • Release early in the morning or in late afternoon.
    • With the vial held horizontally, carefully remove the lid. This should be done among the plants.
    • Regulate release of wasps by gently tapping and inclining the vial while walking through the crop.
    • Distribute as widely as possible.
    • Stand the bottle in the crop for a few hours to allow any remaining parasites to escape.
    • Use yellow sticky traps to monitor adult leafminer emergence.
    • For advice on recommended release rates, consult your technical specialist.

Storage and transport

  • Keep in darkness at 50-59°F/10-15ºC until use.
  • Keep out of direct sunlight.
  • Use within 18 hours of receipt.
