Horseradish flea beetle: Protected with the weapons of its food plant

Researchers demonstrate how the horseradish flea beetle regulates the accumulation of mustard oil glucosides in its body. The beetles have special transporters in the excretory system that prevent the excretion of mustard oil glucosides. This mechanism enables the insect to accumulate high amounts of the plant toxins in its body, which it uses for its own defense.
