This ongoing battle between plants and insects has led to the development of multiple defensive and offensive approaches by both insects and plants. Plants produce a multitude of constitutive and inducible defense barriers to reduce damage by insects. They include physical barriers such as waxy layers and trichomes as well as molecular barriers, ranging from secondary metabolites to proteins...
