The cuticular hydrocarbons of the Triatoma sordida species subcomplex (Hemiptera: Reduviidae)

The cuticular hydrocarbons of the <i>Triatoma sordida</i> subcomplex (Hemiptera: Reduviidae: Triatominae) were ana- lysed by gas chromatography and their structures identified by mass spectrometry. They comprised mostly n-alkanes and methyl-branched alkanes with one-four methyl substitut...

description The cuticular hydrocarbons of the <i>Triatoma sordida</i> subcomplex (Hemiptera: Reduviidae: Triatominae) were ana- lysed by gas chromatography and their structures identified by mass spectrometry. They comprised mostly n-alkanes and methyl-branched alkanes with one-four methyl substitutions. n-alkanes consisted of a homologous series from C21-C33 and represented 33-45% of the hydrocarbon fraction; n-C29 was the major component. Methyl-branched alkanes showed alkyl chains from C24-C43. High molecular weight dimethyl and trimethylalkanes (from C35-C39) represented most of the methyl-branched fraction. A few tetramethylalkanes were also detected, comprising mostly even-numbered chains. Several components such as odd-numbered 3-methylalkanes, dimethylalkanes and trimethylalkanes of C37 and C39 showed patterns of variation that allowed the differentiation of the species and populations studied. <i>Triatoma guasayana</i> and <i>Triatoma patagonica</i> showed the most distinct hydrocarbon patterns within the subcomplex. The <i>T. sordida</i> populations from Brazil and Argentina showed significantly different hydrocarbon profiles that posed concerns regarding the homogeneity of the species. <i>Triatoma garciabesi</i> had a more complex hydrocarbon pattern, but it shared some similarity with <i>T. sordida</i>. The quantitative and qualitative variations in the cuticular hydrocarbons may help to elucidate the relationships between species and populations of this insect group.
