Figure 1 Fig. 1. Cycadothrips responses to M. lucida volatiles. (A) The % of insects going to sporophylls of four mid-pollination-stage male cones (M1 to M4) versus controls (Y-tube tests). Lines are quadratic fits to data from separate cones; fit parameters are not statistically different (5). (B and C) Male thrips physiologically respond [gas chromatography electroantennographic (EAG) detection, GCEAD] (B) to ß-myrcene (peak 1) from male cone volatiles and (C) to (E)-ß-ocimene (peak 3) and allo-ocimene (peak 4) but not to (Z)-ß-ocimene (peak 2) from ocimene standard. (D) The % of insects attracted to different concentrations of ß-myrcene standard versus controls (Y-tube tests). [View Larger Version of this Image (31K GIF file)]
