Identification and bioactivity of alarm pheromone in the western flower thrips,Frankliniella occidentalis.

abstract：:Jasmonic acid (JA) is a key molecule initiating plant defensive responses to herbivory. Our previous work has shown that this phytohormone is often present at high concentrations in eggs and neonates of lepidopteran species. In this work, we document the concentrations of JA found in various tissues of larval H. vires...
