During reproductive phase, larvae of male and female are intermingled in nest of social wasps. Workers care for and feed larvae that gives them an opportunity to bias investment with respect to sex, or even to kill some larvae, if they can distinguish between immature males and females. Cuticular hydrocarbon (CHC) mixtures are the most studied cues for species, nestmate, and caste recognition in social Hymenoptera. In this study, we investigate the paper wasp Polistes dominulus to see if male… Expand
Males and females of the social wasp Ropalidia marginata do not differ in their cuticular hydrocarbon profiles and do not seem to use any long-distance volatile mate attraction cues
TLDR
A behavioral assay failed to show presence of mate attraction at a distance, thereby showing the absence of volatile long-distance mate attraction cues (that may originate from sources other than and in addition to CHCs). Expand
Reproductive Status of Females in the Eusocial Wasp Polistes ferreri Saussure (Hymenoptera: Vespidae)
TLDR
Investigation of factors that indicate the reproductive status in females of Polistes ferreri Saussure found that the queens were among the older females in the colony and were always inseminated, while the age of the workers varied according to the stage of colony development. Expand
Close-range cues used by males of Polistes dominula in sex discrimination.
TLDR
The results indicate that CHCs may be used by males as cues to recognise a potential mating partner in P. dominula, since the focal males displayed specific courtship behaviours exclusively toward females. Expand
Variation of cuticular chemical compounds in three species of Mischocyttarus (Hymenoptera: Vespidae) eusocial wasps
TLDR
The hypothesis that cuticular chemical profiles can be used as parameters to identify interspecific and intercolony differences in Mischocyttarus is supported, highlighting the importance of these compounds for differentiation of species and populations. Expand
Cuticular signature in the development of Polistes versicolor.
TLDR
In this study, cuticle composition was examined during the development of Polistes versicolor from the egg stage to adulthood, with the aim to assess changes in the chemical signature of the species, using gas chromatography. Expand
Age-related changes in the surface pheromones of the wasp Mischocyttarus consimilis (Hymenoptera: Vespidae).
TLDR
The method used was Fourier transform infrared photoacoustic spectroscopy directly on the gaster of each individual to determine the time when adults of the wasp Mischocyttarus consimilis acquire the chemical signature of their colonies, as well as the variation in the cuticular hydrocarbon profiles of the exoskeleton of individuals, according to their functions in the colony. Expand
Linear alkanes as a tool to evaluate intraspecific differences in social wasps
TLDR
The hypothesis is that linear alkanes can be used as a tool to establish intraspecific relationships in a species of social wasp and the results validate the hypothesis that variation in composition of linear alkane can be useful to assess intraspecifical differences in social wasps. Expand
Intraspecific Variation of the Composition of Linear Alkanes in Social Wasp Mischocyttarus consimilis
TLDR
The results show that there is a significant variation between the chemical cuticular profiles of samples from different populations, as well as between castes, sex and newly emergent workers of different ages, suggesting that this class of compounds may vary according to genetic differences between populations, but also by different environmental conditions. Expand
A larval ‘princess pheromone’ identifies future ant queens based on their juvenile hormone content
TLDR
A model for caste determination in H. saltator is developed that incorporates endocrine, pheromonal and behavioural control of caste development in the ant Harpegnathos saltator and demonstrates that workers identify larval caste using a chemical signal present on the cuticle that reflects endocrine changes associated with queen development. Expand
Observation of intra- and interspecific differences in the nest chemical profiles of social wasps (Hymenoptera: Polistinae) using infrared photoacoustic spectroscopy.
TLDR
The hypothesis that the nest chemical profile (NCP) can be used as an additional tool for intra- and interspecific differentiation in social wasps of the subfamily Polistinae is confirmed. Expand

Polistes dominulus (Hymenoptera: Vespidae) larvae possess their own chemical signatures.
TLDR
Larval epicuticular substances are sufficient for recognition of nestmate larvae by adults and demonstrate that wasps are able to discriminate between alien and nestmate larval odours. Expand
Larval sex identification in the paper wasp Polistes dominulus (Vespidae, Hymenoptera)
Abstract.Identifying the sex of larvae is important in social Hymenoptera. Until now for Polistes wasps it has been necessary to genotype larvae at microsatellite loci, and assign their sex based onExpand
Discrimination of larval sex and timing of male brood elimination by workers in honeybees (Apis mellifera L.)
TLDR
Honeybee workers can discriminate the sex of broods for male elimination based on cuticular substances during the larval periods with the highest growth rates, which may avert excessive investments in male brood. Expand
CONFLICTS OF INTEREST IN SOCIAL INSECTS: MALE PRODUCTION IN TWO SPECIES OF POLISTES
TLDR
For two species of Polistes, DNA microsatellites were used to estimate two relatednesses, to determine the sex of brood, and to determine whether male brood was produced by queens or workers, which results do not support collective worker control. Expand
Rank and epicuticular hydrocarbons in different populations of the paper wasp Polistes dominulus (Christ) (Hymenoptera, Vespidae)
TLDR
The aim was to identify specific compounds or sets of compounds which could be general indexes of foundress rank position in an associative foundation and found quantitative and qualitative differences in the epicuticular profile among the three populations. Expand

TLDR
The results suggest that in this species, sex may not become detectable until pupation, which is consistent with sexual deception as an aspect of queen control. Expand

TLDR
The combined data indicate that workers of the Argentine ant are able to identify the sex of the brood and to selectively eliminate male larvae, which appears to fit with the values of the secondary sex ratio observed in this species. Expand
Primary and secondary sex ratios in monogyne colonies of the fire ant
TLDR
The results suggest that workers strongly influence the colony's secondary sex ratio by selective elimination of male larvae, but the magnitude of this influence depends upon the primary sex ratio produced by the queen. Expand

TLDR
It is demonstrated that food supply has an important proximate influence on sex investment, and may explain much of the natural variation in sex investment in populations of eusocial Hymenoptera. Expand
