abstract：:Jasmonic acid (JA) is a key molecule initiating plant defensive responses to attack by pathogens and herbivores. This phytohormone is produced at sites of insect damage and is ingested by feeding insects, but its subsequent occurrence in insect tissues remains to be studied. We report the presence of JA in eggs and ne...
