Fig. 2. The aggressive response of L. humile towards heterospecific
hydrocarbons, structural classes and controls. (A) Argentine ant response to
Formica moki hydrocarbons, individual hydrocarbon structural classes,
mixtures of hydrocarbon classes, hydrocarbons extracted from F. moki,
and controls. (B) Argentine ant response to mixtures of synthetic hydrocarbon
standards and controls. Values are means ± s.e.m. (N=8). The
line above the bars indicates that LSD post-hoc analysis showed no
statistical difference among the treatments.
