Figure 3 From: Modulation of social interactions by immune stimulation in honey bee, Apis mellifera, workers Immunostimulated bees display significantly different cuticular hydrocarbon chemical profiles. Discriminant analysis was performed on the cuticular chemical profiles of sham, saline- and lipopolysaccharide-injected honey bee workers based on their relative proportions of chemical compounds (a, colony SDI8, F(14,46) = 5.69, P < 0.0001). Data were obtained from gas chromatography analysis of cuticular washes. Similar results were obtained for bees derived from a different colony in a second independent trial (b, colony SDI11, (F(26,10) = 6.74; P = 0.0016).Back to article page
