APHIDEND - 1000

What is APHIDEND?

APHIDEND consists of pupae of the gall midge Aphidoletes aphidimyza. The rather fragile gall midges are rarely seen since they are active during the night. They search the crop for aphid colonies and are attracted by the smell of the honeydew that the aphids produce. While the eggs of the gall midge are difficult to find; the yellow-orange larvae stand out between the aphids. Fully grown larvae pupate in the soil.

How does APHIDEND work?

The gall midges do not show a preference for a certain species of aphid. They lay their eggs in aphid colonies. The larvae that will eventually hatch from those eggs are the ones that will control the aphids. They puncture the aphid; sedate it and suck up its contents. An aphid that has been killed by a gall midge larvae hangs from the leave by its stylet and will eventually turn brown or black. The control of the aphid colony can happen rather fast during favorable conditions (i.e. high relative humidity).

How to combine APHIDEND

If you are unsure which aphid species is present in the crop; APHIDEND is great in combination with APHISCOUT. This is a mix of five different parasitoids who are effective during the early stages of an aphid infestation. You can also combine APHIDEND with the parasitoids APHIPAR (against green peach aphid) or APHILIN (against foxglove- and potato aphid).

• Use one bottle of 1000 for 1500 - 2000 m².
• Repeat release weekly until enough gall midges are encountered.

• Open the bottle in the greenhouse.
• Place it on the ground near the crop or hang the bottle opened in the crop.
• Do not scatter the contents!
• The adult gall midges that hatch from the pupae will leave the bottle themselves to look for aphid colonies.
