1. Variation of cuticular chemical compounds in three species of Mischocyttarus (Hymenoptera: Vespidae) eusocial wasps
Abstract The social wasps have a remarkable system of organization in which chemical communication mediate different behavioral interactions. Among the compounds involved in this process, cuticular hydrocarbons are considered the main signals for nestmate recognition, caste differentiation, and fertility communication. The aims of this study were to describe

2. The cuticular hydrocarbons of the Triatoma sordida species subcomplex (Hemiptera: Reduviidae)
The cuticular hydrocarbons of the Triatoma sordida subcomplex (Hemiptera: Reduviidae: Triatominae) were ana-lysed by gas chromatography and their structures identified by mass spectrometry. They comprised mostly n-alkanes and methyl-branched alkanes with one-four methyl substitutions. n-alkanes consisted of a homologous series from C21-C33 and represented 33

3. Estudo comportamental, perfil dos hidrocarbonetos cuticulares e morfologia das glândulas mandibulares e intramandibulares de rainhas de Melipona scutellaris com diferentes idades / Behavioural study, cuticular hydrocarbon profiles and morphology of the mandibular and intramandibular glands of the queens of Melipona scutellaris with differents ages
The virgin queens of Melipona scutellaris, as others species of the genus Melipona, are attacked and killed for workers. As exist few information about recognition of this virgin queens, this work had as purpose to test the hypothesis that the virgin queens of M. scutellaris are identified by workers for the use of chemical signal. For this, the behaviour, t

4. Populational and taxonomical studies of fire ants, Solenopsis invicta (Hymenoptera: Formicidae), and of the phenology of their parasitoids of the genus Psedacteon (Diptera: Phoridae) / Estudos populacionais e taxonomicos de formigas lava-pes, Solenopsis invicta (Hymenoptera: Formicidae) e da fenologia de seus parasitoides do genero Pseudacteon (Diptera: Phoridae)
This work discusses some aspects of the ecology of the fire ant species Solenopsis invicta and its phorid parasitoid flies ofthe genus Pseudacteon, and ofthe taxonomy of S. invicta and S. saevissima, both of which are native to South America. The allometry of S. invicta colonies in southeast Brazil was studied by measurement of mound (aboveground) dimensions

5. Variation in cuticular hydrocarbons among strains of the Anopheles gambiae sensu stricto by analysis of cuticular hydrocarbons using gas liquid chromatography of larvae
Cuticular hydrocarbons of larvae of individual strains of the Anopheles gambiae sensu stricto were investigated using gas liquid chromatography. Biomedical discriminant analysis involving multivariate statistics suggests that there was clear hydrocarbon difference between the Gambian(G3), the Nigerian (16CSS and, its malathion resistant substrain, REFMA) and

6. Ants recognize foes and not friends
Discriminating among individuals and rejecting non-group members is essential for the evolution and stability of animal societies. Ants are good models for studying recognition mechanisms, because they are typically very efficient in discriminating ‘friends’ (nest-mates) from ‘foes’ (non-nest-mates). Recognition in ants involves multicomponent cues e

7. Genetics of a Difference in Male Cuticular Hydrocarbons between Two Sibling Species, Drosophila Simulans and D. Sechellia
In seven of the eight species of the Drosophila melanogaster group, the predominant cuticular hydrocarbon of males is 7-tricosene, but in the island endemic species D. sechellia it is 6-tricosene. The phylogeny of the group implies that the novel hydrocarbon profile of D. sechellia is a derived character. Genetic analysis of hybrids between D. sechellia and

8. Localization of pheromonal sexual dimorphism in Drosophila melanogaster and its effect on sexual isolation.
Drosophila melanogaster is sexually dimorphic for cuticular hydrocarbons, with males and females having strikingly different profiles of the long-chain compounds that act as contact pheromones. Gas-chromatographic analysis of sexual mosaics reveals that the sex specificity of hydrocarbons is located in the abdomen. This explains previous observations that D.

9. Cuticular hydrocarbons mediate discrimination of reproductives and nonreproductives in the ant Myrmecia gulosa
In many species of social insects, the cuticular hydrocarbons of adults vary with both colony identity and individual physiology (oogenesis). Such variations have been shown in some ants and social wasps to function in nestmate recognition, but as yet there is no demonstration of their use by workers to recognize egg layers. We report that in the ant Myr

10. Recognition of social parasites as nest-mates: adoption of colony-specific host cuticular odours by the paper wasp parasite Polistes sulcifer.
Colonies of the polistine wasp Polistes dominulus are parasitized by the permanent worker-less social parasite Polistes sulcifer. After usurpation of the host colony, parasite females are characterized by a change in the relative proportions of their cuticular hydrocarbons to match those of the host species. In this paper we present evidence from field data

11. The nucleotide changes governing cuticular hydrocarbon variation and their evolution in Drosophila melanogaster
The cuticular hydrocarbon (CH) pheromones in Drosophila melanogaster exhibit strong geographic variation. African and Caribbean populations have a high ratio of 5,9 heptacosadiene/7,11 heptacosadiene (the “High” CH type), whereas populations from all other areas have a low ratio (“Low” CH type). Based on previous genetic mapping, DNA markers wer

12. Genetics of a Pheromonal Difference Affecting Sexual Isolation between Drosophila Mauritiana and D. Sechellia
Females of the sibling species Drosophila sechellia and D. mauritiana differ in their cuticular hydrocarbons: the predominant compound in D. sechellia is 7,11-heptacosadiene (7,11-HD), while that in D. mauritiana is 7-tricosene (7-T). We investigate the genetic basis of this difference and its involvement in reproductive isolation between the species. Behavi
