||Caterpillars anticipate plant defense
induction by intercepting plant signals!
|Corn earworms sense and respond to the plant defense signals
jasmonic acid and salicylic acid by increasing production of cytochrome P450s. These
enzymes are important in detoxification of plant toxins. By eavesdropping on the
plant signals, the larvae are able to prepare in advance to process toxic furanocoumarins
produced in celery. Larvae pretreated with the signalling compounds performed
much better when switched to induced plants than larvae that were switched without

Are terpenes toxic to the plants that make them?
Behaviors that allow caterpillars to minimize ingestion of
pressurized terpenes and furanocoumarins
