Lipid cues for seed-carrying by ants in Hepatica americana

The authors investigated the chemical basis for ants carrying the seeds of Hepatica americana , an ant-dispersed plant of eastern North America. A laboratory bioassay of seed and elaiosome extracts was based on the distance test items were carried by Pogonomyrmex rugosus . Ants responded equally to...

Zusammenfassung:	The authors investigated the chemical basis for ants carrying the seeds of Hepatica americana , an ant-dispersed plant of eastern North America. A laboratory bioassay of seed and elaiosome extracts was based on the distance test items were carried by Pogonomyrmex rugosus . Ants responded equally to isolated elaiosomes and to the diglyceride fraction. Diolein was a major component of the diglyceride fraction, which is consistent with a finding that 1,2-diolein releases seed-carrying by Aphaenogaster rudis . Ants' response to the free fatty acid fraction was less intense.
