Aphidoletes aphidimyza (predator) (Rondani, 1847)

The gall midge is an important predator of aphids with a cosmopolitan distribution in temperate and subtropical regions. The female midges lay up to 40 eggs eggs on leaves close to aphid colonies and the larvae prey on a large variety of aphid species. The aphids do not release an alarm pheromone when attacked.

A. aphidimyza is produced commercially and has been used in greenhouses since the 1970s, sometimes in combination with the aphid parasitoid Aphelinus abdominalis. Colonies can be maintained in greenhouses using banker plants.
