“…CHCs have been used for species differentiation of some insects including parasitic wasps [12], phlebotomines [13,14], anophelines [15,16], culicids [17], triatomines [18,19] and the forensically important Diptera Calliphoridae [20-27] and Sarcophagidae [28]. …”

A species-specific complex mixture of highly stable cuticular hydrocarbons (CHCs) covers the external surface of all insects. Components can be readily analyzed by gas chromatography coupled to mass spectrometry (GC-MS) to obtain a cuticular hydrocarbon profile, which may be used as an additional tool for the taxonomic differentiation of insect species and also for the determination of the age and sex of adult and immature forms. We used GC-MS to identify and quantify the CHCs of female and male Chrysomya putoria (Wiedemann, 1818) (Diptera: Calliphoridae) from one to five days old. CHCs ranged from C21 to C35 for females and from C21 to C37 in males. Major compounds were the same for both sexes and were 2-MeC28, C29:1, n-C29, 15-,13-MeC29, 2-MeC30, C31:1, n-C31 and 15-,13-MeC31. The relative abundance of each component, however, varied with age. Cluster Analysis using Bray-Curtis measure for abundance showed that cuticular hydrocarbon profiles are a strong and useful tool for the determination of age in adult C. putoria.

“…Chemical analysis of cuticular hydrocarbons offers a non destructive and reliable chemotaxonomic method (De Renobales et al, 1991). Also, the chemotaxonomic tools solve the different taxonomic problems, for example, the morphological similarity as the members of the Anopheles gambiae complex (Anyanwu, et al, 2000); differentiation of sibling species of sandflies (Ryan et al, 1986).…”

The outer surface of insects (cuticle) is sheltered by a complex mixture of cuticular hydrocarbons (CHCs) play an important role in avoiding desiccation and defend the insects against diseases infestation. Identification and chemical analyses of insect cuticular hydrocarbons are vital practice toward insect control. The obtained results indicated the two studied species obviously differ in CHCs components (35 and 29 components characterized B. oleae and B. zonata respectively) and shared twelve components. All these components can be used (quantitatively and qualitatively) to identify and taxonomically separate them.The objective of this paper is to evaluate the using of cuticular hydrocarbons as taxonomic tools in two dipteran species, Bactrocera oleae and B. zonata.

“…melas were found to show different constituents of cuticular and internal hydrocarbons by gas chromatography. Such assays require only a single specimen for discrimination of species [30,31,32]. This variance in hydrocarbon content of the cuticle may explain the desiccation tolerance of some species over others.…”

Entomological indices and bionomic descriptions of malaria vectors are essential to accurately describe and understand malaria transmission and for the design and evaluation of appropriate control interventions. In order to correctly assign spatio-temporal distributions, behaviors and responses to interventions to particular anopheline species, identification of mosquitoes must be accurately made. This paper reviews the current methods and their limitations in correctly identifying anopheline mosquitoes in sub-Saharan Africa, and highlights the importance of molecular methods to discriminate cryptic species and identify lesser known anophelines. The increasing number of reports of Plasmodium infections in assumed “minor”, non-vector, and cryptic and novel species is reviewed. Their importance in terms of evading current control and elimination strategies and therefore maintaining malaria transmission is emphasized.
