Background and Objective: Although the usage of cuticular hydrocarbons profiles in differentiating between mosquitos’ species and subspecies, their role in identification and differentiation of the developmental stages is scarce. The objective of this study was to determine differences in cuticular hydrocarbons (CHCS) among developmental stages of Aedes caspius and Culex pipiens mosquito vectors in order to examine their reliability in mosquito classification. Materials and Methods: Mosquito immatures were collected from breeding habitats found around Al-Hfouf Oasis, eastern Saudi Arabia by the aid of special long aquatic net and chemical analysis of cuticular compounds was performed by gas chromatography. Results: Eleven hydrocarbons, n-alkanes, with carbon numbers from C9-C19 were identified from the developmental stages of both mosquito species and their levels varied significantly among these stages. The variation was quantitative rather than qualitative and the major n-alkane in all developmental stages was C12 except for C. pipiens females (C11) whilst the lowest one was differed according to the stage. Conclusion: The present findings reporting qualitative differences in CHCS among developmental stages of A. caspius and C. pipiens mosquitoes and supporting their application and reliability as a marker to assist in identifying the immature stages of mosquitoes.
