Chemical ecology and social parasitism in ants.
It is hypothesize that host and parasite are likely to be related chemically, thereby facilitating the necessary mimicry to permit bypassing the colony odor barrier, and discusses evolutionary trends that may have led to social parasitism, focusing on whether slave-making ants and their host species are expected to engage in a coevolutionary arms race.

Commensal bacteria play a role in mating preference of Drosophila melanogaster
In this study, mating preference was achieved by dividing a population of Drosophila melanogaster and rearing one part on a molasses medium and the other on a starch medium and it was confirmed that symbiotic bacteria can influence mating preference by changing the levels of cuticular hydrocarbon sex pheromones.

Individuality and colonial identity in ants: the emergence of the social representation concept
It is hypothesize that the template of colonial identity has evolved from a simple personal chemical reference in primitive species with small colonies to an internal representation of the colonial identity in larger colonies. Expand
Bionomics of the Large Carpenter Bees of the Genus Xylocopa
The large carpenter bees of the genus Xylocopa include more than 730 species, which are grouped into 48 subgenera, and include some of the largest bees, often exceeding 3 cm in length. Expand
Primer pheromones in social hymenoptera.
Social insect are profoundly influenced by primer pheromones (PPhs), which are efficient means for maintaining social harmony in the colony. PPhs act by affecting the physiology of the recipientsExpand
Direct Behavioral Evidence for Hydrocarbons as Ant Recognition Discriminators
The escape response versus the quiescent response of the American cockroach: behavioural choice mediated by physiological state. Expand
Camponotus fellah colony integration: worker individuality necessitates frequent hydrocarbon exchanges
The results clearly support the existence of a Gestalt colony odour in C. fellah, and show that since individual hydrocarbon production is dynamic, workers are obliged to exchange hydrocarbons continually in order to be in the Gestalt, and properly integrate into the colony. Expand
Juvenile hormone titers, juvenile hormone biosynthesis, ovarian development and social environment in Bombus terrestris.
The results show that reproduction in B. terrestris is strongly affected by the social environment and the influence of the environment on reproduction is mediated by JH, and the rate of JH biosynthesis measured in vitro is not a reliable indicator ofJH titer or ovarian development in the bee.

The evolution of hydrocarbon pheromone parsimony in ants (Hymenoptera: Formicidae) - interplay of colony odor uniformity and odor idiosyncrasy. A review
An alternative solution is proposed whereby workers have variable discrimination thresholds and response to differences in the pheromone blend, large or small, in a contextdependent manner. Expand
