This clip shows aphids (Myzus persicae on Chinese cabbage) responding to alarm pheromone. A colony is on a leaf, a syringe delivers some alarm pheromone (you can just about see it at the start of the clip). After perceiving the alarm pheromone, the aphids become agitated and move away. Video by Christine Woodcock.
