Sex, Age and Ovarian Activity Affect Cuticular Hydrocarbons in Diacamma Ceylonense, a Queenless Ant
Journal of Insect Physiology, 2001 In the queenless ant, Diacamma ceylonense, the cuticular hydrocarbons (C25-C35) of nestmate workers vary in their proportions according to age and fertility.

A Review of Ant Cuticular Hydrocarbons
Journal of Chemical Ecology, 2009We compared the published cuticular hydrocarbon (CHC) profiles of 78 ant species across 5 subfamilies. Almost 1,000 CHCs have been described for these species, composing 187 distinct homologous series and ten hydrocarbon groups. In descending order of occurrence were: n-alkanes > monomethylalkanes > dimethylalkanes > alkenes > dienes>> trimethylalkanes>

Cuticular hydrocarbons fromVarroa jacobsoni
Experimental and Applied Acarology, 1992The cuticular hydrocarbons fromVarroa mites collected in Florida and Italy and their honeybee hosts were characterized by gas chromatography (GC) and by coupled GC-mass spectrometry (MS). AVarroa mite has a hydrocarbon pattern that is qualitatively identical to that of its honeybee host.

Cuticular hydrocarbons of the sunflower beetle, Zygogramma exclamationis
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2003Hydrocarbons were the major lipid class on the cuticular surface of adults, nymphs, and eggs of the sunflower beetle, Zygogramma exclamationis, characterized by gas chromatography-mass spectrometry. Minor amounts of wax ester from 40 to 48 carbon atoms in size were only detected in larvae.

A developmental study of the cuticular hydrocarbons of Sarcophaga bullata
Journal of Insect Physiology, 1975Abstract The accumulation of cuticular hydrocarbon was measured throughout the life of Sarcophaga bullata. Less than 5 μg hydrocarbon per insect are present until the third larval instar when synthesis increases the quantity present to 10 to 20 μg by pupariation.

Regulation of insect cuticular hydrocarbon biosynthesis
Current Opinion in Insect ScienceCuticular hydrocarbons (CHCs) play pleiotropic roles in insect survival and reproduction. They prevent desiccation and function as pheromones influencing different behaviors. While the genes in the CHC biosynthesis pathway have been extensively studied, the regulatory mechanisms that lead to different CHC compositions received far less attention.

A simple method for analysis of insect cuticular hydrocarbons
Journal of Chemical Ecology, 1990Cuticular hydrocarbons from tiny pieces of insect cuticle can be analyzed directly by gas chromatography without solvent. The cuticle, sealed in a glass capillary, is introduced into the heated injector area of a gas Chromatograph, and the glass capillary crushed after heating for 4 min.

Cuticular Hydrocarbons and Aggression in the Termite Macrotermes Subhyalinus
Journal of Chemical Ecology, 2004Cuticular hydrocarbons are among the prime candidates for nestmate recognition in social insects. We analyzed the variation of cuticular hydrocarbons in the termite species M. subhyalinus in West Africa (Comoë National Park) on a small spatial scale (< 1 km).
