Fig. 4 in Preference of Neoseiulus californicus (Acari: Phytoseiidae) for volatiles of Bt maize induced by multiple herbivory

Fig. 4. Chromatograms of volatile compounds extracted from leaves of conventional maize plants infested by Tetranychus urticae (C + Tu); conventional maize plants infested by Tetranychus urticae and Spodoptera frugiperda (C + Tu + Sf = +); Bt maize plants infested by T. urticae (Bt + Tu); Bt maize plants infested by T. urticae and S. frugiperda (Bt + Tu + Sf). The compounds observed in analysis were 1 = (E)-Hex-2-enal; 2 = heptanal; 3 = (E)-Oct-2-enal; 4 = ˛-pineno; 5 = ˇ-cisocimeno; 6 = ˇ-Ciclocitral; 7 = 1-metil-6- (3-metilbuta-1,3-dienil)-7-oxabiciclo[4,1,0]heptano; 8 = ˇ-ionona; 9 = no identificated = C9; 10 = (E)-7-tetradecen-1-ol; 11 = no identificated = C11; 12 = Linolenic acid ethyl ester; 13 = no identificated = C13.
