...Lucas Baumgart; Marti Wittke; Svenja Morsbach; Bérengère Abou; Florian Menzel ABSTRACT Maintaining water balance is vital for terrestrial organisms. Insects protect themselves against desiccation via cuticular hydrocarbons (CHCs). CHC layers are complex mixtures of solid and liquid hydrocarbons...

..., the cribellate thread is one of the earliest thread types that was specialized to capture prey. In contrast to other capture threads, it lacks adhesive glue and consists of nanofibres, which do not only adhere to insects via van der Waals forces but also interact with the insects' cuticular hydrocarbon (CHC...

... Faso. Survival strategies were studied through morphometric (wing length), ecophysiological (respiratory gas exchanges), biochemical (cuticular hydrocarbons composition) and molecular (AKH mRNA expression levels) parameters, variations of which are usually considered to be hallmarks of aestivation...

... Cuticular hydrocarbons Fertility cues Animal contests occur when individuals attempt to monopolise a resource such as a mate, prey or shelter. To limit costly fights, individuals can estimate their own condition (self-assessment) or compare their condition with that of their rivals (mutual...

.... niger as inhibitors of ovary development in workers, and as modulators of aggression by workers. A recent study showed that in 36 monomethyl-branched cuticular hydrocarbons (MBCHs) isolated from species from nine different orders of insects, the stereochemistry of the MBCHs was conserved, with all...

... and ecdysteroid titers in hemolymph, ecdysteroid content of the ovary and cuticular hydrocarbon (CHC) profiles in the caste-monomorphic, epiponine wasp Polybia micans Ducke. We found that the JH titer was not elevated in competing queens from established multiple-queen nests, but increased in lone queens...

...Adrian A. Smith; Jocelyn G. Millar; Lawrence M. Hanks; Andrew V. Suarez SUMMARY Contact pheromones in the form of cuticular hydrocarbons are widespread among insects. Eusocial insects present a special challenge for understanding the evolution of the cuticular hydrocarbon profile because this blend...

...Stephan Kühbandner; Sergej Sperling; Kenji Mori; Joachim Ruther SUMMARY The surface of insects is covered by a complex mixture of cuticular hydrocarbons (CHCs) to prevent desiccation. In many species these lipids also have communicative functions, but often it is unknown which components...

... cuticular hydrocarbons (CHC), of genetic and/or environmental origin serve as recognition cues. Most invasive populations of the Argentine ant, Linepithema humile (Mayr), display minimal nestmate–non-nestmate discrimination, resulting in low levels of intraspecific aggression allowing free movement...

...Yongliang Fan; Dorit Eliyahu; Coby Schal SUMMARY Cuticular hydrocarbons of arthropods serve multiple functions, including as barriers to water loss and as pheromones and pheromone precursors. In the oviparous German cockroach, Blattella germanica , long-chain hydrocarbons are produced by oenocytes...

... complexity in ant hydrocarbon recognition cues, we studied the species recognition response of two ant species, Linepithema humile and Aphaenogaster cockerelli , and the recognition of conspecifics by L. humile . The cuticular hydrocarbons of ants are composed of molecules of varying chain lengths from three...
