“…Several parasitic hymenopterans have whole-body fatty acid compositions that exactly mimic the host on which they are reared (Thompson and Barlow 1983). Successive generations of parasites reared on different hosts always adopted the fatty acid profile of the host on which they were reared (see Howard 1992), and dietary alkanes can be incorporated directly into the cuticular hydrocarbons of tobacco hornworms (Nelson et al 1971). We cannot exclude the possibility that the spider hydrocarbon profiles are simply contaminants from the digestive tract, since the spider extracts were obtained from the entire body of the spider.…”

Predatory spider mimics acquire colony-specific cuticular hydrocarbons from their ant model prey

The integrity of social insect colonies is maintained by members recognising and responding to the chemical cues present on the cuticle of any intruder. Nevertheless, myrmecophiles use chemical mimicry to gain access to these nests, and their mimetic signals may be acquired through biosynthesis or through contact with the hosts or their nest material. The cuticular hydrocarbon profile of the myrmecophilous salticid spider Cosmophasis bitaeniata closely resembles that of its host ant Oecophylla smaragdina. Here, we show that the chemical resemblance of the spider does not arise through physical contact with the adult ants, but instead the spider acquires the cuticular hydrocarbons by eating the ant larvae. More significantly, we show that the variation in the cuticular hydrocarbon profiles of the spider depends upon the colony of origin of the ant larvae prey, rather than the parentage of the spider.

“…A number of studies with widely diverse insect species have established that the major site of cuticular lipid synthesis are the cells associated with the epidermal layer or peripheral fat body, particularly the oenocytes. In S. gregariu, Diehl [150,151] It is generally accepted that insects synthesize the majority of their cuticular lipids [155], although several studies [156] indicated that a portion of the dietary alkanes was incorporated into the cuticular lipids. However, based on radio-GC analysis of hydrocarbons following [l-14C]acetate incorporation in a number of species, it appears that most insects synthesize the majority of their cuticular hydrocarbon components and do not rely heavily on dietary contributions [q.…”

The chemistry, biochemistry, and physiology of insect cuticular lipids are reviewed. The types of components present in cuticular extracts are described with special emphasis on the occurrence and identification of the di-and trimethylalkanes and the newly discovered tetramethylalkanes. The methods used in the extraction of cuticular components are discussed, including recommendations to standardize procedures. The structural elucidation of methylalkanes, particularly the mass spectral interpretation of multi-methylbranched alkanes, is reviewed. The biosynthesis of cuticular lipids is discussed with emphasis on the hydrocarbon components, describing elongation reactions and the origin of the methyl branches. The effects of environment and development on cuticular lipids are reviewed.

“…The peaks at J C I 2936 and 3136-3137 in Anastrepha were probably internally methyl branched, but no useful spectra were obtained. Because homologous series of 2-methylalkanes and other alkanes described herein have been identified by GCMS in many insect species [12][13][14]18,19], they are not illustrated here.…”

Cuticular alkanes obtained from larvae and adults of six species of tephritid fruit flies, Anastrepha ludens, A. suspensa, Ceratitis capitata, C. rosa, Dacus cucurbitae, and D. dorsalis were analyzed by gas chromatography. The same four major alkanes were shown to be present by capillary GC-mass spectra in all Anastrepha and Ceratitis larvae. Profiles were obtained from individual larvae and adult specimens that showed statistical differences between species, whereas profiles of conspecific life forms including pupae of A. suspensa from different locations showed some similarities. Sexual dimorphism was not observed in alkanes extracted from adults. A novel series of alkadienes was found in all Anastrepha and Ceratitis but not in Dacus.
