“…Also, the method is suitable to trace up hybrid ticks in nature (Eslxada-Pefia et al, 1992b). Gas chromatography of surface hydrocarbons has been used for cluster analysis in Drosophila virilis species group (Bartelt et al, 1986), the results of which were in agreement with the known phylogeny of the group. The method has also been tested in studies on population relationships in Aedes species (Kruger et al, 1992).…”

Estrada -Pefia, A. and Dusb~ibek, F., 1993. Cuticular hydrocarbon gas chromatography analysis of Argas vulgaris, A. polonicus and their hybrids. Exp. Appl. Acarol., 17: 365-376.The cuticular hydrocarbon gas chromatography of adult ticks obtained from experimental homogamic and reciprocal heterogamic crosses of Argas vulgaris (Vv) and A. polonicus (Pp) confirmed both argasids to be closely related species, but easily differentiated by several critical compounds. Cuticular mixtures contained variable amounts of n-alkanes, monomethyl-, and dimethyl-alkanes, without traces of detectable alkenes. Specimens from heterogamic crosses synthesized new high molecular weight compounds not detected in parental cuticular mixtures. Data on genetic identity revealed a close proximity of parental adults, but a high distances between and within their hybrids. A relatively high percentage of heterozygosity (32.12% in females and 20.00% in males) of F t Pv generation in comparison with F I Vp (14.54% and 8.48% respectively) and both P2 generations (6.66 -9.09%) has also been ascertained.

“…There compounds with 23 and 25 carbons had double bond positions on internal carbons 11-13, instead of 7-9, which surprisingly recalls CHCs of the virilis group of the genus Drosophila (Bartelt et al 1986;Liimatainen and Jallon 2007).…”

“…Interspecific comparisons of Drosophila cuticular hydrocarbons have been done only in two species ensembles, in the virilis group of species of the Drosophila subgenus (Bartelt et al 1986) and in the melanogaster subgroup of the Sophophora subgenus (Jallon and David 1987) accompanied by some functional studies. In both ensembles, major CHCs were linear unsaturated compounds with a small number of double bond positions, while branched compounds were abundant in neither ensemble.…”

Evolution of Cuticular Hydrocarbons of Hawaiian Drosophilidae

et al. 2010

Hawaiian Drosophila offer an excellent model for adaptive evolution. More than 500 species are reported in Hawaiian islands, and there is considerable diversity in behavior and morphology. Such diversity is mainly driven by sexual selection. In this study qualitative and quantitative chemical compositions of cuticular hydrocarbons (CHCs) in 138 flies belonging to 27 Hawaiian Drosophila species, picture-winged and non picture-winged, were analyzed regarding sexual dimorphism, differences in saturation, branching position, and lengths of CHCs. We found significant variation in the CHC patterns. In several subgroups, new species show decreases in unsaturated hydrocarbons, and gradual increases in branched compounds, monomethylalkanes and dimethylalkanes, not commonly found in Drosophila. Moreover, branching positions gradually shifted towards internal carbons, and chain lengths increased in the new species. The long-term evolution of CHCs in the light of the recent evolutionary migration and adaptation history of Hawaiian Drosophila species along the developing archipelago was discussed.

“…1973). Cuticular hydrocarbons were likewise used in the classification of beetles (Jacob 1979;Page et al 1990), Drosophila species from the Drosophila virilis group (Bartelt et al 1986), and termites (Bagn~res et al 1990;Kaib et al 1991). The concordance between chemical and morphological data that generally occurs makes these chemicals a good tool in taxonomy.…”

Chemistry of the postpharyngeal gland secretion and its implication for the phylogeny of IberianCataglyphis species (Hymenoptera: Formicidae)

et al. 1996

Summary.A comparative morphological and chemical study of six endemic species of Cataglyphis from the Iberian Peninsula: C. ibericus, C. rosenhaueri, C. hispanicus, C. humeya, C. velox and C. Jtoricola and the Moroccan species C. bombycinus is described. The morphological study relied primarily on genitalia characteristics, whereas the chemical study concentrated on the postpharyngeal gland constituents. Cladograms based on the morphological and chemical data were performed using Ward's method. The dendrogram based on morphological features revealed that the Iberian Cataglyphis can be classified into three species groups albicans, altisquamis and emmae. The same pattern occurred when the dimethylalkanes constituents of the postpharyngeal gland were utilised as character states, with a slight displacement of species within the altisquamis group. However, when the complete hydrocarbon blend was utilised major discrepancies in the dendrograms occurred. CatagIyphis velox proved to be very similar to C. bombycinus, whereas C. ftoricola clustered with the other two species of the altisquamis group. Based on the geographical distribution and paleontological data (Tinaut 1993) it is assumed that C. floricola recently invaded the Iberian Peninsula. Based on the chemical findings we postulate that chemical character displacement occurred in C. floricola as a result of its sympatry with C. velox after the former colonized the Iberian Peninsula. We further discuss the possible reason for the different dendrograms obtained when only the dimethylalkanes are considered and its implication for the communicative role of the postpharyngeal gland secretion in these ants.
