Abstract | Cuticular hydrocarbons (CHs) contain complex mixtures of components
that cover the surface of all insects to restrict water loss,
and in many species function in chemical communication. The
complex mixtures have been used as a chemotaxonomic tool
since the 1970s. The majority of CH components can be identified
by gas chromatography-mass spectrometry (GC-MS), allowing
hydrocarbon profiles to be used as chemotaxonomic characters,
which can differentiate insect species, including cryptic species.
The present study used GC-MS for the identification of CHs of
males and females of three species of calliphorids: Cochliomyia
macellaria (Fabricius), Hemilucilia segmentaria (Fabricius) and
Lucilia cuprina (Wiedmann), A comparison of the chromatographic
profiles from the three species allows them to be readily separated.
Hydrocarbons identified from the three species contain 23
to 37 carbons and include n-alkanes, methyl-branched alkanes and
alkenes. The most abundant compound for both sexes of C.
macellaria was n-heptacosane, while for H. segmentaria it was 2-
methyltriacontane; for L. cuprina, however, the most abundant
compound was hentriacontene for females and nonacosene for
males. The results obtained in this study are important for the
establishment of a database to be used in chemotaxonomy of
sanitarily and forensically important insects. | pt_BR |
