Aphids make ‘chemical weapons’ to fight off killer ladybirds

Aphids being attacked by a predatorI stumbled across the results of research from Imperial College, London, UK.  Aphids pick up glucosinolates from consumed plants in their blood which when mixed with an enzyme called myrosinase, which is stored in the muscles,  a violent chemical reaction occurs which releases mustard oil.  This release of mustard oil kills, injures or repels predators.
