Cuticular hydrocarbons as cues of sex and health condition in Polistes dominula wasps
In the paper wasp Polistes dominula, cuticular hydrocarbons play a critical role to acquire information regarding conspecific individuals. However, the relationship between cuticular hydrocarbons, health status, ...

Termite’s royal cradle: does colony foundation success differ between two subterranean species?
Colony foundation modes play a key role in social insect societies as they strongly impact colony survival. In subterranean termites, we do not yet know which factors most influence the early stages of colony ...

Chemical Heterogeneity in Inbred European Population of the Invasive Hornet Vespa velutina nigrithorax
Invasive social insect populations that have been introduced to a new environment through a limited number of introduction events generally exhibit reduced variability in their chemical signatures (cuticular h...

Competition between invasive and indigenous species: an insular case study of subterranean termites
An important requirement for the management of invasive species is to identify the biological and ecological factors that influence the ability of such species to become established and spread within a new env...

High occurrence of colony fusion in a European population of the American termite Reticulitermes flavipes
The coexistence of multiple unrelated reproductives within social insect colonies decreases the relatedness among colony members and therefore challenges kin selection theory. This study investigated the colon...

The breeding system and population structure of the termite Reticulitermes grassei in Southwestern France
We assessed colony and population structure in three French populations of the termite Reticulitermes grassei using eight polymorphic microsatellite loci. Although most colonies contained the offspring of multipl...

Colonial and geographic variations in agonistic behaviour, cuticular hydrocarbons and mtDNA of Italian populations of Reticulitermes lucifugus (Isoptera, Rhinotermitidae)
The subterranean termite, Reticulitermes lucifugus (Rossi), is found throughout Italy. The purpose of this study was to assess variations among colonies collected from the north to south of Italy. A multidiscipli...

Intra-colony, inter-colony and seasonal variations of cuticular hydrocarbon profiles in Formica japonica (Hymenoptera, Formicidae)
The cuticular hydrocarbons of a formicine ant, Formica japonica, were characterized by gas chromatography and gas chromatography-mass spectrometry. Variations in cuticular hydrocarbon profiles of two natural col...

Biosystematics of Reticulitermes termites in Europe: morphological, chemical and molecular data
In Europe the most abundant naturally residing termite is the subterranean genus Reticulitermes (Rhinotermitidae). Six phenotypes of Reticulitermes have been identified on the basis of morphological, chemical (c...

Social Signals Involved in Scent-Marking Behavior by Cheek-Rubbing in Alpine Marmots (Marmota marmota)
The Alpine marmot Marmota marmota is a territorial rodent. Resident adults regularly scent-mark their territory by cheek-rubbing, mainly on burrow entrances and along boundaries. The purpose of this three part st...

Artificial neural network modeling of caste odor discrimination based on cuticular hydrocarbons in termites
Individuals in an insect colony need to identify one another according to caste. Nothing is known about the sensory process allowing nestmates to discriminate minute variations in the cuticular hydrocarbon mi...

Does group closure exist in the social spider Anelosimus eximius ? Behavioural and chemical approach
The exclusion of a conspecific intruder by the members of a colony is a well-known phenomenon in social insects. This phenomenon is called group closure. It may exist in social spiders as well. ¶Experiments w...

Polistes biglumis bimaculatus epicuticular hydrocarbons and nestmate recognition (Hymenoptera, Vespidae)
An experimental analysis was conducted to determine if chemicals from the cuticle of a social wasp are used in nestmate recognition. These chemicals were also subsequently identified. Laboratory colonies of Poli...

The postpharyngeal glands and the cuticle of Formicidae contain the same characteristic hydrocarbons
Comparison of the contents of the postpharyngeal gland and cuticular hydrocarbons of five species of ant have shown them to contain the same compounds and to be characteristic of the species. For four species (Fo...
