Abstract
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 F1 Pv generation in comparison with F1 Vp (14.54% and 8.48% respectively) and both P2 generations (6.66–9.09%) has also been ascertained.
