“…was shown for larvae of the eastern spruce budworm Choristoneura fumiferana (Ascoli and Albert, 1985), and attraction to host plant volatiles was demonstrated for codling moth larvae, Cydia pomonella (Sutherland and Hutchins, 1972;Knight and Light, 2001). Codling moth larvae respond to the sesquiterpene a-farnesene that occurs in the waxy coat of several apple varieties (Sutherland and Hutchins, 1972) and, more recently, these larvae were shown to be attracted by ethyl and methyl esters of (E,Z)-2,4-decadienoic acid, emitted from pears (Pyrus communis) at threshold levels of 1 ng and 1 mg, respectively (Knight and Light, 2001). Neonate larvae of Spodoptera frugiperda were attracted to DMNT which was induced in cowpea (Vigna unguiculata) by conspecific herbivory, and showed even higher attraction when DMNT was supplemented with plant material (Carroll et al, 2008).…”
