Cannibalism in Spodoptera feeding on tomato – but don’t rely on spraying with jasmonic acid as an insect control just yet

Interesting article on cannibalism in Spodoptera feeding on tomato. The authors tested the hypothesis that induced defences benefit tomato plants by encouraging insects to eat other members of their species. They reported that defences which promote cannibalism benefit tomatoes in two ways: cannibalism directly reduces herbivore abundance and cannibals eat significantly less plant material. This is a previously unreported means of defence which offers food for thought on future insect control measures and plays on plant–herbivore dynamics.
