Mode of action
Adult gall-midges are active at night and are attracted to aphid colonies by the smell of honeydew. Eggs are deposited in the aphid colonies. Larvae paralyse the aphids and suck out their contents.
Aphids killed by the larvae hang on the leaf, connected by their mouthparts. Consequently they shrivel, turn brown or black and decay.
