Cuticular hydrocarbon patterns of L. neglectus. (a) Cuticular hydrocarbon profile of L. neglectus, consisting of 24 hydrocarbon peaks. Hydrocarbon peak 15* was only found in the Warsaw population. Peak numbers correspond to the following compounds: 1, 11C31:1; 2, C31; 3, 13MeC31; 4, 3MeC31; 5, C33:2; 6, C33:2; 7, C33:2; 8, 12C33:1 + 13C33:1; 9, 10C33:1 + 11C33:1; 10, 7C33:1; 11, 13Me21C33:1 + 13Me23C33:1; 12, 13MeC33 + 15MeC33; 13, 3Me21C33:1; 14, 3Me23C33:1; 15*, 10,23diMeC33; 16, 3MeC33 + 5,15diMeC33; 17, 12,14,22Me21C34:1 + 12,14,22Me23C34:1; 18, C35:2; 19, C35:2; 20, C35:2; 21, 21C35:1; 22, 23C35:1; 23, 13,15Me21C35:1 + 13,15Me23C35:1; 24, 13MeC35 + 15MeC35 ('imp' denotes impurity). (b) Discriminant analysis of all 14 populations (mean and standard error of three to seven nests per population), with the first and second extracted root (and the variance they explain). Populations are coloured according to the genetic clusters (Figure 2).
