Aphidoletes aphidimyza
Adult midges only fly in the evening and in the night, and will be seek for honeydew in colonies of aphids. In the colonies the orange eggs are layed close to the aphids. The gallmidge larvae hatching from the eggs will start eating aphids by paralysing and thereafter sucking them. Developed larvae are around 4 mm. in length, will crawl or fall to the ground when ready to pupate. A cocoon is formed. In normal conditions (20-25 degrees Celsius), the new generation of midges hatches within 2 weeks. Aphidoletes can control nearly all species of aphids in all kind of cultures.
