Aphidoletes aphidimyza
Contrary to some other gall midge species, Aphidoletes aphidimyza does not cause damage by forming galls on leaves. The adults feed on pollen and nectar. A female has an excellent searching ability for aphid hot spots where she lays more than hundred eggs. The larvae are voracious predators preferring almost all aphid species. Immediately after hedging they start sucking aphids empty. One larva needs minimum 5 aphids for its development, but it will kill more than necessary. Aphidoletes aphidimyza is applicable on several crops.
