Plutella xylostella (IMAGE) Max Planck Institute for Chemical Ecology Caption A diamondback moth (Plutella xylostella) on the leaf of the model plant Arabidopsis thaliana, which is a member of the crucifer family and uses the same defense mechanism as cabbage. This pest insect, which is widespread throughout the world, is adapted to the chemical defense of cabbage and related crops. It is also difficult to control chemically because it quickly develops insecticide resistance.
