This amazing midge was first characterized by researchers in Germany. It was a contaminant in an Aphidius trial. The trial was a failure because all of the Aphids disappeared. They noted the midge and larvae but could not believe that the Aphidoletes could be so effective until subsequent experiments proved that Aphidoletes is as effective as they originally suspected.
We sell Aphidoletes in 5 packages;

1. 250 tray; ideal size for hot spot treatment or prevention in an area of less than 2500 square meters
2. 1000 tray; ideal size for preventative release program for an area of less than 10,000 square meters. As rate goes up, this tray will create multiple release point per Hectare.
3. 3000 concentrate vial; this is the most cost effective way of purchasing, but it requires action to ensure adequate performance. Vial must be distributed into 1 or more release chambers immediately upon receipt. Emergence chambers must have controlled humidity and Ant exclusion characteristics.
4. 250 Max vial; this is the simplest form. Just hang the vial near the hot spot and walk away.
5. 5000 A-Bomb; this product was originally developed as a Whitefly control for extreme Bemisia hot spots in Poinsettia. It is economical and suited for outdoor release for crops such as Hop, Pecan etc.

When not cold stored, Aphidoletes has a tremendous searching ability, capable of finding individual Aphids within the crop. Cycling both indoors and outdoors readily occurs if enough Aphids are present. Aphidoletes overwinter by diapause, triggered by short days.
Aphidoletes are effective against all Aphid species (except Woolly Aphid), Adelgids, and will also control Whitefly hot spots, if Aphids are unavailable. We have used them inundatively against the Potato Psyllid, where they feed on the juvenile stages, but they need to be placed in the hot spots as they cannot find the Psyllids by smell.
