Frequency of some behavioural patterns in colonies of Kalotermes flavicollis (Isoptera Kalotermitidae): the impotance of social interactions and vibratory movements as mechanisms for social integration

Behavioural repertoires of individuals from different developmental stages and castes of the lower termite Kalotermes flavicollis were investigated by focal animal sampling performed on laboratory colonies. The study focuses on those behavioural patterns used as means of communication in inter-individual transmission of information. Vibratory movements, especially those performed by nymphs, appear to communicate short-term colony needs through mechanical-tactile stimulation. Allogrooming patterns among colony members seem the most likely way to exchange messages through pheromones spreading, and the interactions with the reproductives emphasize the key role they assume on receiving and transmitting signals on which the regulation of social equilibrium is probably based.
