...Jeanne Brülhart; Anja Süß; Jan Oettler; Jürgen Heinze; Eva Schultner ABSTRACT Juvenile hormone is considered to be a master regulator of polyphenism in social insects. In the ant Cardiocondyla obscurior , whether a female egg develops into a queen or a worker is determined maternally and caste...

...David Baracchi; Martin Giurfa; Patrizia d'Ettorre ABSTRACT Decision-making processes face the dilemma of being accurate or faster, a phenomenon that has been described as speed–accuracy trade-off in numerous studies on animal behaviour. In social insects, discriminating between colony members...

...Matteo A. Negroni; Marah Stoldt; Marie Oster; Ann-Sophie Rupp; Barbara Feldmeyer; Susanne Foitzik ABSTRACT During the evolution of social insects, not only did life-history traits diverge, with queens becoming highly fecund and long lived compared with their sterile workers, but also individual...

The queen pheromone of the ant Lasius niger was among the first queen pheromones of social insects to be identified. Its major component is 3-methylhentriacontane (3-MeC 31...

Studying JH functions across social insect species is important for understanding the evolution of sociality; however, these studies have been limited because of the inability to reduce JH levels without surgically removing its...

...Elva J. H. Robinson; Ofer Feinerman; Nigel R. Franks SUMMARY Social groups are structured by the decisions of their members. Social insects typically divide labour: some decide to stay in the nest while others forage for the colony. Two sources of information individuals may use when deciding...
