The insect ingests plant tissue containing the fatty acids, an enzyme in the gut conjugates the plant-derived fatty acid to an insect-derived amino acid to form an elicitor, When plants recognize elicitors from insect saliva induces some typical responses such as

a) Increasing Ca2+ levels in the cytosol and then activate an array of target proteins, such as calmodulin and other Ca2+-dependent protein kinases

b) In Arabidopsis, a calmodulin-binding transcriptional regulator called IQD1 was identified as an important mediator of defense responses against insect herbivory

c) overexpression of IQD1 in Arabidopsis activate the herbivore activity

d) IQD1 binds calmodulin, a major Ca2+-binding protein, in a Ca2+-dependent manner and subsequently inhibits the gene involved in glucosinolate biosynthesis
