Book Description
The ecological success of social insects is largely based on the complex organization of their colonies. In a honeybee colony, the adjustment of labor is expected to be highly adaptive. Because biotic and abiotic factors like temperature, brood rearing conditions and nectar availability strongly fluctuate, the honey resources which are shared between all members are of crucial importance for the colony's survival. The questions posed are whether there is a performance-related reward system, what controls individual differences in performance, and how such systems might have evolved. This work focuses on the activity of the antennae at initiation of a feeding contact, impact of sugar and water content of food to the heating performance, behavioral differences between donors and recipients of a trophallactic contact, regulation of the trophallactic activity on the brood comb, and possible evolution of the performance related reward system which triggers the feeding and heating activity. The various methods used for fielding the questions in this thesis reach from classical behavioral ecology, behavioral physiology, neurobiology, and theoretical approaches.

Book Description
Claire Detrain, Jean-Louis Deneubourg and Jacques Pasteels Studies on insects have been pioneering in major fields of modern biology. In the 1970 s, research on pheromonal communication in insects gave birth to the dis cipline of chemical ecology and provided a scientific frame to extend this approach to other animal groups. In the 1980 s, the theory of kin selection, which was initially formulated by Hamilton to explain the rise of eusociality in insects, exploded into a field of research on its own and found applications in the under standing of community structures including vertebrate ones. In the same manner, recent studies, which decipher the collective behaviour of insect societies, might be now setting the stage for the elucidation of information processing in animals. Classically, problem solving is assumed to rely on the knowledge of a central unit which must take decisions and collect all pertinent information. However, an alternative method is extensively used in nature: problems can be collectively solved through the behaviour of individuals, which interact with each other and with the environment. The management of information, which is a major issue of animal behaviour, is interesting to study in a social life context, as it raises addi tional questions about conflict-cooperation trade-oft's. Insect societies have proven particularly open to experimental analysis: one can easily assemble or disassemble them and place them in controllable situations in the laboratory.

Book Description
Honeybees (Apis mellifera) are characterised by a sophisticated division of labour among the workers, organized as a temporal polyethism. An important task within the colony is the thermoregulation of the brood nest to maintain an average temperature of ca. 35°C. To record the developmental temperature of the honeybee brood with a high spatial and temporal resolution, a new device was developed, consisting of a grid of 256 thermistors. To investigate the impact of developmental temperature on the division of labour among adult workers, brood was raised in incubators and emerging adults were individually marked and monitored in observation hives. Workers developed under higher temperatures were found to start foraging at younger age. However, a deterministic computer model suggests that this effect has no impact on the division of labour on the colony level. A further experiment addressed the relevance of empty cells in the brood nest area in terms of thermoregulation. No impact of those "gaps" could be determined.
