Table 2 Terpenoid concentration (ng/mg DW) in pulverized leaves of Bt and non-Bt cotton (Bollgard II), which were used for the bioassays with Drosophila melanogaster. “Infested” indicates that the plants were infested with one Heliothis virescens larva for 7 days prior to the harvest of the leaf material. Values are means ± SE; n = 20 subsamples per treatment.
