The role of terpenoid natural products in plant defense against herbivory by insects has been well established.1–2 This phenomenon extends to arid and semi-arid plants, even though taxa from these latter habitats have been less frequently examined.3 In this chapter, we compare the terpenoid chemistry of desert sunflowers of the genus Encelia, with the performance of a generalist insect feeding on extracts of these plants, in an attempt to define the role of the terpenoid allelochemicals as protective agents against herbivory.
