Social organization of nest emigration inLeptothorax (Hym., Form.)
A hypothesis is discussed that the severity of the ecological conditions inside the old nest affects the behavioral threshold of workers to respond to the signals of a tandem calling nestmate. Expand
Tandem calling pheromone in the genusLeptothorax (Hymenoptera: Formicidae): Behavioral analysis of specificity
Comparative behavioral analysis with 11 species of Leptothorax demonstrated a subgenus specificity of the tandem calling pheromone between the subgeneraLeptothsorax andMychothorAX. Expand
Myrmecophilic Relationship of Pella (Coleoptera: Staphylinidae) to Lasius fuliginosus (Hymenoptera: Formicidae)
A large number of staphylinid beetles are closely associated with ants and termites (for review see Wilson 1971, Kistner 1979). Those species living with ants are commonly called myremcophiles. AtExpand
The foraging system ofPheidole militicida (Hymenoptera: Formicidae)
It was demonstrated that the foraging pathways of P. militicida are marked by very enduring chemical cues, which might be distinct from the poison gland trail pheromone, which seems to play a role in the directional maintenance of the trunk route. Expand
Communication by tandem running in the antCamponotus sericeus
Camponotus sericeus recruits nestmates to newly discovered food sources or nest sites by the tandem running technique and it is demonstrated that the follower ant is bound to the leader by a surface pheromone. Expand
Communication and orientation during foraging and emigration in the antFormica fusca
Although the comparative analysis of the organizational levels of recruitment techniques employed by different formicine species does not necessarily provide direct evidence of the evolutionary pathways of recruitment behavior, it at least allows us to develop a model of the evolution steps leading to the highly sophisticated stage of mass communication.

Stone dropping by Conomyrma bicolor (Hymenoptera: Formicidae): A new technique of interference competition
Summary1.The dolichoderine ant Conomyrma bicolor interferes with the activity of other desert ants when their nest entrances are in close proximity. C. bicolor workers surround these nests, pick upExpand
