Fig. 2 in Whole body solvent soak gives representative venom alkaloid profile from Solenopsis invicta (Hymenoptera: Formicidae) workers

Fig. 2. Gas chromatograms of hexane extracts obtained from Solenopsis invicta workers by different extraction methods. Capillary milking, gland dissection, and body without gland represent chromatograms from the sequential extraction of the same individual ants; whole body represents the chromatogram from whole body solvent-soaking extracts of 20 intact workers.
